What's so bad about the 2420? Isn't it the fastest?
edit : this one says 1ms GtG, the 2420 was 2ms iirc. They are still 5ms TN panels btw.

ZERO MOTION BLUR INSTRUCTIONS
I have now posted a new universal guide on my BlurBusters Blog, that works on all LightBoost-enabled ASUS and BENQ monitors. Enables blur-eliminating strobe backlight mode for 2D. No shutter glasses needed!

Windows 7 and Windows 8 compatible:
LightBoost HOWTO: Instructions for Zero Motion Blur on LightBoost LCD's
No shutter glasses needed!

Works with all known LightBoost monitors:
ASUS VG278H
ASUS VG278HE <-- reportedly not as good LightBoost as VG278H
BENQ XL2420T
BENQ XL2411T <-- Really good. Low lag. Virtually zero 3D crosstalk.
ASUS VG248QE <-- Really good. Low lag. Virtually zero 3D crosstalk.
ACER HN274H

Samsung 700D / 750D / 950D can benefit from zero motion blur using Samsung strobe backlight HOWTO (non-LightBoost, ATI Radeon compatible, more input lag)

What are your thoughts about the XL2411T?

I own both an ASUS VG278H and a BENQ XL2411T, and am testing comparisions. They both have different pros and cons. If I was a discerning competition gamer that needed minimum input lag, my vote goes for the BENQ.

You simultaneously gain the CRT quality sharp motion and the near-CRT-quality input lag, even if you don't get CRT-quality color (BENQ has a crimson tint during LightBoost)

Since there is zero motion blur with LightBoost, both look the same from a motion blur perspective. However, there's far less inter-frame crosstalk on the BENQ (On the ASUS, there is occasionally a faint sharp double-image like 3D glasses crosstalk). If you get the glasses emitter for the BENQ, you'll get much better stereoscopic 3D than with the ASUS. I have never, never seen an LCD with near-zero crosstalk between refreshes. The new "1ms panel" actually makes an impressive difference, especially when combined with LightBoost. Turning on LightBoost completely eliminates all trailing artifacts -- all ghosting and coronas completely disappear.

It appears that the strobe backlight is well-timed on the BENQ to occur almost exactly when the pixel hits final value. So both pixel persistence (and RTC overshoots) are kept in total darkness, and are both successfully hidden by the human eye, thanks to the LightBoost strobe backlight. (For ASUS, YouTube 1000fps camera proof: http://www.youtube.com/watch?v=hD5gjAs1A2s ) The color captured during the strobe is +/- less than one-half percent of the final pixel color value; the most accurate I've ever seen!

After enabling LightBoost, you can do PixPerAn Chase Test 1 pixel apart -- gap is perfectly visible at 960 pixels per second. Best I've ever seen on LCD. Yes, 1 pixel apart in chase test. Text speed 30 in PixPerAn (but you need good fast eyes, and move your head while reading text.). You used to only get this with CRT. Now you can on LCD.

Now, if the colors were properly calibrated & IPS, we'd be in heaven -- but it will probably be a while before we have IPS+LIghtBoost+low lag...

For BENQ XL2411T, here's a very impressive PixPerAn image by immetjes of the overclockers.co.uk forum:
http://i.imgur.com/9P50U.jpg
There is no visible trailing unless you really use a mangifying glass. This image looks exactly the same time in all repeated photograph attempts -- it doesn't even vary.

Thanks for the very informative post.

Do you happen to know if this LightBoost stuff will work on Windows XP?

I only play very old games that run at really shitty frame rates under Windows versions newer than XP.

I missed this and almost bought a 3d vision kit! Thanks for the link, I've got it working on my BenQ under Win8 thanks to the excellent instructions.

TIPS!

***The BENQ XL2411T Crimson Fix
There has been several reports of a crimson color when using LightBoost with a BENQ XL2411T (the new 1ms monitor). This is the solution.

***Via Monitor Menus
Monitor’s Contrast Setting = 65 …. (If using nVidia Gamma 1.10)

***Via nVidia Control Panel – “Adjust Desktop Color Settings”
Adjust them individually, R, G, B.
—
R Contrast = 30%
G Contrast = 45%
B Contrast = 30%
—
R Brightness = 10%
G Brightness = 40%
B Brightness = 10%
—
R,G,B Gamma = 1.10

Make sure to readjust Monitor OSD contrast everytime you change Gamma. nVidia Gamma 1.10 worked best with a monitor OSD Contrast of 65. With these settings, I can see the difference between RGB(0,0,0) and RGB(1,1,1), without a wrongly tinted color in backgrounds or in dim colors.

***Still Too Bright?
LightBoost keeps things bright for 3D, but may make things dimmer for 2D (when not wearing 3D glasses). However, if it is still too bright, then try lower the "LightBoost" setting instead of "Brightness" or "Contrast". It dims the picture. Lowering the "LightBoost" setting (but don't go all the way to "OFF") actually improves motion clarity because of shorter strobe flashes. LightBoost MAX corresponds to 2ms strobes, and LightBoost MIN (not OFF) corresponds to 1.4ms strobes.

Do you NEED nVidia?

yes

somebody needs to hack it and make it work on AMD cards! :D

tested this with my Samsung 750D ..

and its total crap. image gets to dark and colors loose alot. 3D hasnt really the same picture quality as 2D mode and there is so little motion blur on the samsung 120hz even before this, that i dont see any difference while playing.

so either im doing something wrong or this stuff is just decreasing your experience when owning a samsung

i've experienced no ghosting on my 2420. heard the 2410 was rather dreadful though.

I have the 2410 and the ghosting isn't noticeable unless you're looking for it

http://www.youtube.com/watch?v=kqFPDrDWAHs

I didn't notice it when I first got the monitor and I don't notice it now while playing, but I can see what people complain about.

guess so

I would like to know if this is better than the 2420t model too.

My all mighty CRT is about to die, i will most certainly try to fix it but i need an alternative anyway, so i would also like to know which is the best in terms of input lag, the xl2420t or the xl2411t. Also didnt found any input lag test about the 144hz asus VG278HE. If anyone got some info please post in this thread ;)

there's a VG278H review on prad.de, VG278HE review gets released on 26.11.12, if I were you I'd certainly buy asus over benq

Ty man.

5ms (VG278HE) vs 3.4 on the benQ.

http://gaming.benq.com/gaming-monitor/xl2420t/specification/#skip
One of these.

how do the old monitors (2233rz, vx2268wm) compare with the newer models?

price is lower than XL2420T
In same shop in Moscow XL2411T ~247 euro and XL2420T ~289 euro.
imho cheapest and one of the best lcd 120hz model atm

tut bazar o 11T esli 4e, da i voobwe 10T & 20T trash, ne best ni razu

ya opechatalsya. esli tak to 2233rz kak nazvat'?

Update, here is the review (in german) of the Asus VH278HE 144hz monitor.

I think this is very interresting, worth buying a 3D vision 2 panel : http://marky.com/backlight/zeromotionblur/

http://pcmonitors.info/benq/benq-xl2411t-120hz-of-gaming-goodness
apparently its a 144hz monitor? :o

Yes it is 144hz, i had some customer feedback on it and they comfirmed it is 144hz out of the box!

I'm not sure it's really 144Hz. Yes it shows up on the list and you can select it, but my ingame fps (Dota2) stays at 120. Need a high speed camera and see how many real frames you get per second.

Maybe your game is caped at 120fps, you can try Warsow which is free and set it to 144hz via the console, then enable vertical sync and unlock the fps via the console, see if it works.

you can check how many hz is set at the momet in the monitor menu
and use /fps_max in dota console to change it

Ok so it was set to 120. I've upped fps_max to 144 and it reports 144 no problem.

you'll probably get tearing in case of hz=fps(unless you're using vsync), I'd use 150fps or smth

Full Review http://pcmonitors.info/reviews/benq-xl2411t

I fired up Call of Duty: Black Ops 2 for some faster paced on-foot action.

smiled :)

great review tho, it looks like its very compareable to the xl2420t, especially for ql's 125 fps (i might be wrong here but 144hz @125 fps might result in some flickering)

I ordered one of these monitors then later decided to google some reviews. Ended up on this page :)

My monitor should be here tomorrow so I'll let you know what I think. Unfortunately haven't played much FPS recently so I'm not the best person to judge but I'll do what I can.

Funny thing... I feel like I lost a bit of interest in FPS ever since flat panel monitors replaced CRTs. I wonder if it's something to do with playing at 60Hz. We'll find out soon I suppose.

Greetings to you my good sir. My crt is almost totaly dead, in fact i had to let it cool down 1 hour today to have it back working, i will be waiting for your review ;)

I wasn't planning to do a review, but I can give you my general impression. Essentially it works at 120Hz from what I can tell. Colour reproduction, viewing angles etc. I don't really care about - it seems ok. I'm sure an IPS panel would technically look better but again I don't really care. Everything seems more responsive.

I know subjective reviews aren't much help and I don't have a CRT lying around to compare my feelings with a known factor. All I can say for sure is that it is much better than using a 60Hz panel.



Here's a timer photo alongside the Asus monitor I was using before. It's pretty much identical. I expect there is still a certain amount of input lag, but without a side-by-side CRT I can't really work out how much. You might throw away your CRT and wish you didn't later...

If I was going to do a review I'd have to invest in a high speed video camera to study individual frames. I don't have one though, so this is pretty much all you're getting!

I installed Windows 8 yesterday aswell in an effort to get with the times. Now I've just realised that I have no idea how to increase the polling rate on my WMO1.1A. Anyone know how to do this?

Invest in a Steelseries Kana whilst you're buying all this stuff too i guess :D

Well if there's really no way to change polling rate in Windows 8 I might have to change mouse. It seems a shame to pay money when the new mouse isn't going to be better than the old one.

Or just get a Zowie ec1 evo which has 1k hz out of the box. No drivers needed.

Installing drivers isn't a deal-breaker!

Well its still the best mouse I have tried (unless you have ~55-60 cm/ 360).

I agree though installing drivers isnt a dealbreaker, unless they are called synapse.

btw fresh post with information about common image delays of some 120hz LCDs and review by quaker Renzo:
http://www.quakeworld.nu/news/841/review-asus...hz-monitor
...
While we don't get a true 0ms input lag, the total latency or image delay is 7,3ms. As for comparison the most common image delays are:
Samsung 2233RZ: ~15ms
BenQ XL2410T: ~10ms
BenQ XL2420T ~8ms
...

I have to precise that this is for the Asus VG278HE, i hope the 2411t does better. By the way that would be interresting if prad.de could make the calculation while using this trick : http://www.techngaming.com/home/guide/tips/el...boost-r485 !!

Thanks for this, it really works! Just tried it on my VG278H. Its like a CRT now!

EDIT: The screen is a bit darker in 3D Always mode. No big deal. Quakeworld has never been so smooth.

Can you give me your registry entries please? I want to see if I can get lightboost on without buying the 3d kit.

I believe it will be:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\NVIDIA Corporation\Global\Stereo3D

There are lots of entries in "Stereo3D". Do you want me to export them and then send you a file? Or a screenshot?

Either/Or - I spent about an hour fiddling with the registry last night trying to make it work so at this point I'll try anything :)

File is nice and easy though - if you post a comment and edit it, you are able to attach files to the comment.

Done.

Attached Misc File: 92249-3d.reg (24KB)

I imported these settings and I'm pretty sure it worked. I took more pictures of my screen and there was no ghosting whatsoever! Thanks so much! Pictures below...

Awesome!

Too bad I get some weird headache in this mode :( I don't think my eyes/brain like it. I'll only use it for QW and TF2.

Hmm ok I came home and tried again and now I'm not sure whether lightboost is on or off. Is there a noticeable different in brightness? I might just get a 3d kit to try it out for real.

Well on my Asus its slightly less bright in 3d mode and monitor OSD shows you if its in 3d or not.

Yes, there's a noticeable difference in brightness. You don't have to test games to confirm LightBoost. You can confirm LightBoost is enabled by going into your monitor's settings and confirming that settings are very different (lots of adjustments disabled):
LightBoost is enabled, if:
(1) The screen dims somewhat relative to non-LightBoost (Because it's now strobing a short time period, only once per refresh)
(2) The monitor now prevents you from adjusting settings.
(3) There is now zero motion blur when you drag windows around -- text stays crystal sharp when you drag a web browser window around the screen.

You can also use PixPerAn to test, too. The text "NEED MORE SOCKS" in the PixPerAn racecar is crystal sharp even when the racecar moves at 960 pixels per second (CRT style, instead of LCD style). You may see a very different ghost trail effect but it should extremely faint on the newest 1ms monitors (e.g. XL2420T, tec)

Set Brightness to 92 during LightBoost mode. The picture will now look brighter, without clipping any colors.

So one would need to have the official Nvidia IR Emitter to do this? No software/registry option?

Oh man do I have to buy an IR emitter to enable this? There must be a way without?

I'm still waiting for VG248QE, although xl2411t finally got one more AMA option with less aggressive overdrive, Asus still got better overdrive implementation and probably faster panel itself.

Interrestingly both brands use 24" 144hz 1ms 3dvision 2 pannels, maybe they are supplied by the same factory ?

I bought the XL2420T, it was the best monitor at the time and after purchasing it I asked NVC what his complaints were about it (I know it was a ghosting issue).

The issue comes with AMA. If this model has it, some people might not like it. It's hard to explain, but there is a ghosting effect that is quite noticable once it's pointed out. I can't find the link for it, but honestly after playing with and without AMA, it's not that bad. AMA just tries to reduce the amount of ghosting the monitor does. AMA off has a lot of ghosting, AMA on does not.

I played on an Asus 120hz at IPL and it didn't have that effect that AMA had. Unfortunately, it's not as good (glossy screen, fixed height and position) so the BenQ in my eyes is still the one to get.

People who don't like AMA won't probably like this monitor either, assuming it has AMA, and assuming they haven't improved or fixed AMA from the previous versions.

they've introduced 1 more setting of AMA which isn't so aggressive. I've linked the review few posts above

There are 3 settings for AMA on the XL2411T: Off, High and Premium. I'll have a play with them later.

With AMA off it feels unplayable. Even on premium it's bad. I've had to leave AMA on "High"

I'm sorry but, what is AMA?

this

Ty for this imformative post man. Do you know what technology Asus use to avoid ghosting and stuff?

Did you even read it? It's all the same, just different manufacturers call it different things. ASUS happen to call it Trace-Free.

nvc talking out of his ass!!! :) I see this is a very important subject which is realy a good reason to be that rude.

Just kidding. For exemple BenQ has a technology that they call AMA-z which introduce something different from traditional Response Time Compensation Technology. Since english is your native language maybe you noticed something i didn't! Actualy their is no mention about Asus on that page.

So in all gentlness may i send you back your question which was : "Did you even read it?" I'm quite sure you didn't read all the page.

I whacked up the shutterspeed on my camera to see if I could get some meaningful images showing the difference in AMA settings.

Set cl_yawspeed 1000 and +left:



No doubt my camera isn't the best for testing this, and there is some aspect of timing that will affect the visual effect. However, I'm sticking to AMA: High for now.

UPDATE: Have managed to get lightboost turned on. Seems like lightboost removes a lot of the ghosting. I took more photos, and yes I'm still +left with cl_yawspeed 1000



Have to go out for a bit but I'll try this again and see if I can get the Quake logo back on that screen in aerowalk since it demonstrates the ghosting much better.

The placebo effect is strong. I've been trying to toggle this lightboost stuff on and off using the registry settings but there's really not any noticeable different in screen brightness so now I'm not sure if it's working. I tried to create identical situations and took photos of the screen at 1/250 but in the end there wasn't enough change to prove that lightboost was on.

Anyway here's the collage I put together using cl_yawspeed 2000 and +left. I'm using the lights on the wall as my reference point for ghosting.

test using this: http://www.prad.de/en/monitore/testsoftware/pixperan.html

i have the monitor now also.

may i ask you both to post ppa settings as well?

ur tests are wrong coz AMA options is disabled when lightboost ON(when monitor in 3d mode).

yea i thought it would probably get darker if lightboost was working

Are you sure Lightboost is successfully being turned on and off between the tests? In your first six screenshots there was a clear difference.

Not sure at all. I'm going to get a 3d kit and see if I can confirm lightboost.

It may be that the quake live logo colours made ghosting more apparent.

You can't use stationary photographs to take pictures of the LightBoost difference. It's not possible. You need to take highspeed video (e.g. Casio 1000fps) to capture the LightBoost strobing in action.

You need a tracking camera setup (google "Motion Picture Response Time Camera") but those are really expensive. Cameras that simulates eye movement by moving the camera to follow a moving object.

Best way is to use motion test software like PixPerAn, and test the chase test before and after.

BlurBusters Blog -- Zero Motion Blur LCD Tricks

The idea of the camera was to show how many frames are visible on screen at one time and so how bad the ghosting was. I'm not sure why this wouldn't work?

Well, in theory you can see how much blur there is behind the moving car, it's just realy visual, not mesaurement since this would require an external peripheral for that task. For exemple on my CRT, i see an absolut cristal clear car even if i set it to move very fast, even tho at speed 16 if you watch very closely you will see the phosphore persistance.

Now on my other PC with a 60hz LCD Iiyama ProLite E2607WS, the car is totaly blury at speed 16.

There is another programe to test over drive which could possibly show more results, it's called OverDrive tool by Samsung or Iiyama can't realy remember http://forum.hardware.fr/hfr/HardwarePeripher...295_29.htm

There's no motion blur at all. The PixPerAn car is perfectly clear.
I even see "I NEED MORE SOCKS" text clearly even when it's moving at speed 16.

The Benq XL2411T (1ms) seems to have a better CRT mode than the Asus VG278H (2ms) based on some recent tests on HardForum. Much brighter LightBoost and shorter strobes (which means less motion blur)

If you're counting frames captured, the best way to do this is to use a shutter speed equalling the refresh rate -- e.g. 1/120th second shutter. That will amplify the difference between LightBoost and non-LightBoost.

Be noted, you will sometimes catch the trailing end of the previous LightBoost strobe flash and the leading end of the next LightBoost flash, if you timed your photo coincidentially. So that would be a false double-image, which is actually never on-screen, but an artifact of your camera shutter length long enough to touch the two strobes.

So use an ever so slightly shorter shutter speed to compensate for that chance. Thus, ideal shutter speed would probably be 1/125sec because that, itself, adds a slight safety margin to avoid catching the leading/trailing ends of the LightBoost strobes. (ASUS and BENQ LightBoost strobes backlight is about 1-2ms flashes per refresh, some poster on HardForum did some tests on the BENQ and it is surprisingly reporting a honest 1ms -- so BENQ wasn't lying, at least in LB mode)

That way, all photos taken at 1/125sec will have a double-image effect on non-LightBoost monitors, and no double-image effect on LightBoost monitors. It does not actually tell what the human eye saw, but it is the most amplified-difference way to test.

I would understand the strict requirement for an IR Emitter to enable LightBoost in 2D mode if this 3D technology worked for everyone, because in many ways it's taking away from potential sales. But it does not, and will not ever, work for me in 3D mode... it's quite literally impossible. I'll never spend 100+ on something that i simply cannot use for it's intended purpose, just to activate something that is already there. I'm hoping NVIDIA adds an option to enable LightBoost in 2D mode, because right now it feels like Activision selling map packs that were already on the CD at launch.

All of this assuming that it does what you and other people say it does!

Let's wait for some russian hack back up on that case!

Just tested lightboost technology with my 120hz LCD LG W2363D that doesnt support it natively.
I have done this by creating .inf(driver for monitor) via "Monitor Asset Manager" of "Asus VG278H" that has integrated 3D Vision IR Emitter. Reboot needed after aplying this .inf to monitor. After reboot last beta nvidia drivers(310.70) let me use 3D Vision IR Emitter and ofc lightboost technology. Monitor has gone in 3d mode that disabled THRU Mode(zero input lag) and RTC(response time compensation) in monitor OSD. In test http://www.prad.de/en/monitore/testsoftware/pixperan.html it's noticeably that another algoritm of ghotsting compesation is using. After this i tested in qw lgc3 (1v1 LG fight with bot). My monitor LG W2363D has a bit high pixel response time thats why i will not use lightboost. May be it will be usefull for 120hz monitor with low pixel response time and without 3D Vision IR Emitter(3D Glasses).

Software and EDID inf at
http://3dvision-blog.com/forum/viewtopic.php?f=14&t=2025

That doesn't work for me on 310.70, after installing the ASUS VG278H, and reinstalling NVIDIA 310.70, i still can't click 'next' on the USB IR Emitter page.

i've done it, omg it's amazing, literally.

i'm gonna try this tomorrow :)

Could you please make a full how to? :)

1. Install the ASUS 27" 144Hz EDID (VG278H) via device manager, restart PC. (http://3dvision-blog.com/forum/download/file.php?id=113)
2. Make sure windows is set to 120Hz
3. Goto NVIDIA drivers, check the box to 'Enable Stereoscopic 3D'.
4. Assuming it has worked, it should now list the 'ASUS VG278H' monitor as the Stereoscopic 3D display type, and not '3D Vision Discover' which is there by default.

If you've restarted your PC and you still don't see the ASUS monitor under stereoscopic 3D, try swapping to another DVI-D port on your graphics card.

5. In this same section, set the drop down box for stereoscopic 3D to 'Always Run'.
6. Launch Quake 3 / Quake Live et voilla!

In games that support 3D, you might have to uncheck 'Enable Stereoscopic 3D' before launching to prevent the game launching into 3D mode automatically. Once open, check the box.

After some usage i'm not decided as to whether i'll use it or not. Don't get me wrong, it's brilliant, but it has it's issues. To revert the above changes just uninstall the EDID profile via device manager again. Do the above at your own risk.

glhf!

Enabling and disabling "Always run 3D" might be a crap in nvidia control panel. Better way to check is 3D enabled now or not in monitor OSD. Are there any blocked options in your XL2411T OSD when he's in 3D mode?

Thanks!

It works great. I didn't need to do the EDID stuff, since I already had a "Asus 120Hz 3D LCD" setting. My Asus VG278H LCD looks a like CRT!

One issue is reduced brightness, but I fixed most of that by increasing the Brightness to 92. Most other settings on my VG278H is disabled during LightBoost, though.

What we need is a simple utility that turns on/off this mode via a single button or hotkey. So we can use it only when we need it. (zero motion blur LCD).

Hi, do you mean over drive can't be enabled when you activate lightboost?

Overdrive is internally force-enabled at specific settings when LightBoost2 is enabled. That's why overdrive adjustments are disabled.

Interresting ty. Question is to know now if the overdrive is at max when Lightboost is on.

It's absolutely necessary for overdrive to be max when LightBoost is enabled. This is because the LCD needs to refresh as fast as possible, to finish refreshing before the LightBoost strobe backlight flash (and 3D shutter glasses opening), and before the next refresh begins.

is it possible to do this on the 2420t as well?

yes

Yes, it is. Someone needed to use the Monitor INF override that forces the BENQ to think it's an ASUS, because that unlocks the settings in nVidia Control Panel, apparently.

Also, we noticed that BENQ has a much brighter LightBoost than ASUS

thanks, so you still use the same .inf file gave by nvc and follow the same procedure?
isn't there a risk in messing the monitor up with these changes?

news? 2410 as well?

"n games that support 3D, you might have to uncheck 'Enable Stereoscopic 3D' before launching to prevent the game launching into 3D mode automatically. Once open, check the box."

How do you do that? Or rather where. Running 296.70 with a benq xl2410t and everything seems to work but when I start a game everything lags until I press ctrl^t (disable stereoscopic effects)

Does this disable the good effect of this whole process? I have applied 'Hide stereoscopic effects when game starts' Same question again, does this disable the good effects of this..

Where do I disable the 3d effects per game?

Windows 8 compatible instructions for both BENQ and ASUS:
LightBoost HOWTO: Instructions for Zero Motion Blur on LightBoost LCD's
No shutter glasses needed!

What exactly did you do to that inf file?

just opened it(inf) in "Monitor Asset Manager" and saved as inf :D just to test software )

Wait, wait.

Are you saying you got Lightboost working with a LG W2363D monitor?

(I have one of those :oo)

I just tested that 3D mode can be enabled with this manipulations on LG monitor. Only some 120/144hz models supports nvidia lightboost. Now i have BENQ XL2411T.

Monitors confirmed to have zero motion blur with the LightBoost strobe backlight:
ASUS VG278H, ASUS VG278HE, BENQ XL2420T, BENQ XL2411T, Acer HN274H

Also, it is reported that the ASUS VG278HE (“E” model) has worse LightBoost than the the ASUS VG278H monitor. The LightBoost in BENQ XL2411T is vastly superior to the ASUS models.

from http://marky.com/backlight/lightboost-zero-motion-blur/

Man this CRT mode is amazing. Quakeing like its 1999. Its so smooth. You can easily see the difference even on slower games like TF2.

This shit should be essential for Quakeworld players. For some reason QW was always the most "ghosty", more than QL or TF2. I mean even at 120hz there was always some ghosting. Asus is my 3rd 120hz monitor and they all had it.

But this trick removes ghosting/blur completely!

It kinda sucks for text reading and web browsing so I turn it off for 2d stuff.

EDIT: I don't feel any added input lag. I hope someone tests this.

Even if it added 5ms input lag, it doesn't matter. The zero motion blur effect is making me react 100-200ms faster in video games. It's as if I eliminated "human brain lag" because I don't have to stop moving to identify faraway enemies. You know those tiny far-away snipers? You can't identify those while you're turning on a normal LCD. But you can now identify everything while you're moving, without stopping and becoming a sitting duck! Everything is SO perfectly clear even while you're moving, you frag faster, and you are less of a sitting duck.

You used to do this with old LCD:
... move-pause(wait for blur)-shoot-move-pause(wait for blur)-shoot

So you're doing this with LightBoost or CRT
... move-shoot-move-shoot

With a WHOPPING 100-200ms less human brain lag in fast-twitch FPS video games, especially Arena types games!
That more than BLOWS AWAY any increased input lag!!

COMPETITION GAMERS TAKE NOTE!!!
You are going to be PWNED BY LIGHTBOOST USERS!!!!!
Reaction is 100-200 milliseconds FASTER !!!

This is where you're wrong, lower input lag is far more important than using Light Boost in 2D mode to eliminate all trailing. If anything, it helps to reduce eye strain but for a player using it on a 120hz monitor that he's already had for some time, it will not improve his game to the extent you believe it wil - especially not by 100-200ms lol.

This is a band-aid fix and whilst brilliant in many ways, is not the final solution to ghosting due to it's varied performance based on FPS. On the BenQ XL2411T if you look very closely the overdrive artifacts are still there, just extremely faint (and mostly irrelevant). For whatever reason i can't use this lightboost method over long periods, the flickering is painful.

No, we're _both_ right, for different reasons.
Here are some facts:

-- Some will be more sensitive to the disadvantages. Flicker, eye strain, etc. Some people will be more sensitive to 8ms input lag, while others are fine until it's 15ms input lag. The latter type of person is the type that will benefit more.

-- Some games do not benefit as much. Close combat will not benefit nearly as much. Low input lag will be more important for close combat. There is little to no reaction time advantage during close combat. Input lag WILL be more important.

-- However, if you're playing an Arena type game in wide-open spaces, the faster reaction times afforded by identifying faraway enemies faster. Example is TF2 or Quake Live in the wide-open space maps with lots of faraway snipers that are tiny (a few pixels wide). You can't easily see them while you're still moving around on LCD, but you can on a CRT (have you seen LCD and CRT side by side for faraway sniper-identification while moving? Blurry soup on LCD, sharp on CRT). Here, you gain a 100-200ms reaction time advantage because you've identified the enemy before you've stopped turning.

-- It's already shown that whatever tiny input lag is in LightBoost (e.g. 1ms extra) is outweighed by the motion blur reduction. What some of us may disagree on is _where_ the cutoff point is. It's agreed there's some benefit. But how much? However, is LightBoost worth more than 1ms input lag? Is LightBoost worth more than 5ms input lag? Opinions will differ, but some in other forums are already agreeing LightBoost is more important than a certain amount of "X" ms lag. The disagreement is the "X" only.

Example, some people agree with me. Inu on HardForum said:
... "I can confirm this works on BENQ XL2420TX
EDIT: And OMG i can play scout so much better now in TF2, this is borderline cheating."

Do not take my word for it. I'll let other gamers speak for themselves :-)

i disagree, youfor now you still don't know how much input lag it could possibly add. But the difference between 5ms and 15 is HUGE mate.

Watch who you're talking to. I designed an Arduino-powered input lag meter, see my blog post at www.blurbusters.com (scroll down to see my October 18th, 2012 post)

The lag added by LightBoost is NOT 5ms to 15ms -- it's nearly zero added input lag. However, I reiterate the following:

It's already shown that whatever tiny input lag is in LightBoost (e.g. 1ms extra) is outweighed by the motion blur reduction. What some of us may disagree on is _where_ the cutoff point is. It's agreed there's some benefit. But how much? However, is LightBoost worth more than 1ms input lag? Is LightBoost worth more than 5ms input lag? Opinions will differ, but some in other forums are already agreeing LightBoost is more important than a certain amount of "X" ms lag. The disagreement is the "X" only.

Bottom line.... The faster reaction time of zero motion blur MUST be factored into the whole total equation of videogaming. Being able to identify small/faraway enemies without stopping moving (and becoming a sitting duck for snipers), does outweigh _some_ certain level of X ms lag. Maybe it's not 5ms, but perhaps someone will give up half a millisecond of lag to get zero motion blur, another might give up 2 milliseconds, etc. Giving up X millisecond of lag in order to gain the zero motion blur reaction time advantage. Again, the disagreement is the "X" only.

Let me tell you this again: Regardless of any input lag that light-boost adds (which feels like zero added), nobody in their right mind would willingly add input lag to their monitor to achieve 'zero motion blur'. That includes the act of replacing their lower input lag 120Hz monitor that does not support light-boost, with one that has higher input lag but does support it. That's forgetting the part where it will potentially cause them headaches too.

Again, the current range of 120Hz monitors, with the exception of the BenQ producing overdrive artifacts, already do motion blur good enough for the fastest of FPS games when it comes to your performance in-game. But here is where my second issue with your statements lie, the only current 120Hz monitor that has low enough input lag to replace the great monitors of the first and second generation is the BenQ XL2411T, but if people don't like light-boost they've now got an inferior monitor in almost every other area.

The reality still is that this technology is not perfect. Where a constant 120FPS is unobtainable without spending a ridiculous amount on a 2/3 GPU SLI/XFire setup, not only do you then break the bank, but also potentially introduce micro-stuttering and input lag whilst you're at it. Plus, of course, the chance of headaches that some will get.

You're not selling this product as complete, your instead forcing your opinion on something that's fatally flawed in a number of ways onto people. You might know what you're talking about from a technical perspective... and i'll agree that if you can withstand the headaches it does make the XL2411T an amazing monitor (potentially the best). But if you can't compete with someone who's tried this fix in-game, don't pretend to know better than the players and how it will benefit them... stick to numbers and prove what you can by factual evidence, we all appreciate what you do and that should be your forte.

What you should be saying is this: If the monitor you own supports light-boost then use it, why the fuck not... it's amazing and adds no noticeable input lag. However, don't go upgrading to one that does if you already own a low input lag 120Hz monitor... not unless you either have money to burn, or know that you can return it later if it does cause you issues.

peoples visual reaction is more than 100ms. even if lightboost mode adds 10ms input lag (but i dont fell any added input lag) i will keep lightboost mode on coz increase overall feelings of game for me. btw there is way to disable 120 fps cap(guess coz of adaptive vsync) in some games when monitor in 3d mode(lightboost).
my mention is based on experience playing quake3\ql on lcd75hz, crt 100hz, last 2+ years on lcd 120hz lg w2363d, now benq xl2411t 120hz with lightboost.

i dont know what you both guys ate but... Ok well, if the lightboost methode reduce blur and realy add nothing more than 1ms lag then its worth it ofc. Also mdrejhon looks prety aware of all what you said and he is in the right direction trying to calculate the added lag.

On a sidenote i have my hands on a 250hz beast CRT since 1 week (totaly insane, and a huge difference btw my old 200Hz crt and this one), it works on windows but in QL it seems to be max 200Hz somehow, is QL caping refresh rate? Anyone got programs to force refresh rate?

is there a crt that does more than 170hz on decent resolutions (640x480 and onwards)?

And you are correct. Every single hz ("true" or "active" hz, not tv advertising) and ms matters and there's almost no limit, so even the newest benq still isn't as good as a regular crt screen that does 120hz even less so against a professional usage crt. Obviously a tradeoff can be done if it enhances the overall experience though, 1ms is practically nothing, and motion blur does not belong in quake.

Just stating this in case some newb comes here and says "dude your eyes can't see more than 30fps halo4 rocks!!1! qvak is the gay" as this thread will get popular on the interwebz very soon.

there is motion blur in quake on 120hz lcds without lightboost. just try PixPerAn software to test ur monitor or monitors. with xl2411t with lightboost it's readable.

Yes, mein can do 800x600 @200Hz and 255Hz @ 640x480. As fort the point that the engine is caped at 125 fps, indeed it does change something, you can clearly see it with a special test i discovered which is accurate. Also the delay between the frame produced by the gpu and the rendered by the monitor will be lower. I also tested warsow @ 300fps and 200Hz, its a totaly different world.

there is com_maxfps 125 cap in quakelive. does this 200hz or 250hz helps if u see same 125fps? or u use trick\hack to increase com_maxfps?

Hello guys

I need your help right now :D

I have a BenQ XL2420T and I was able to get into Lightboost 2 Mode (Desktop is really "darker" and I can't change settings on my monitor (it says Lightboost 2 anyway).

My problem is that I have only 60 FPS in Counter-Strike: Global Offensive.

I used different .reg "tweaks" to get into the this mode.
I used these ones:
http://www.esreality.com/download.php?file_id=92249
http://www.scanningbacklight.com/files/ForceL...lasses.reg

Furthermore I used these Asus.inf to be able to choose the monitor in the NVIDIA Menu.
I have really 3d ingame (it just needs to stay 2d) and I need mass fps, that's all.

Can you help me?

no

it's me again :)

It worked now somehow. I installed newest nvidia drivers from 17th december and I unchecked "Enable Stereoscopic 3D".

Now my screen is darker and I can't change settings on my monitor, it says at picture menu "Nvidia 3D LightBoost".

I have ingame the same but now far more than 200 FPS, should be workin now or not? (It feels so smooth like a CRT right now).

However I will get tomorrow the ASUS VG278HE, do I have to do the same stuff? (I don't have the 3D Kit, I bypassed it with the INF installation, so NVIDIA menu thinks I have 3D installed)

Thanks :)

How do I use this?

I have the BenQ XL2420T , what do I download and how do I apply them? I'm kind of confused and would like to give this a try.

Thanks

Mike :)

I followed the steps but I didn't see the "always run" checkbox, even on selecting Asus 120hz LCD under stereoscopic settings. I then launched quake and the green 3d light did come on with desktop going less bright but it wasn't different from normal 120hz and nothing like CRT tbh. Is the difference very easily noticeable ?

what's ur monitor?

Benq xl2420t. Repeated after using the registry file linked above and still no change, always run checkbox is missing.

dunno then, may be u have to install latest nvidia drivers

Tried that too, didn't work. Thanks anyways though, I'll try a more exhaustive google search. I'm running win 8, which could contribute to the problem. I'll reinstall win 7 over the weekend and see if that fixes it.

if you got windows 8 it's here http://prntscr.com/mu9jo

What if one has ATI?

it's impossible with ATI, only with nvidia videocards that supports nvidia 3d vision

Got it (lightboost) to work here with a xl2420t, awesome.
Playing Doom 3 BFG edition with 120 hz, hihi.

this improves QW FFA fun by at least another 100 %:)

somebody tried 3d(lightboost) trick on benq xl2410t?

Yea. It works.

so this trick works out of the box for the BenQ xl2411t without using qny .inf trick? btw how does the lightboost2 realy work? does this trick work for lightboost1 too? is it possible to set AMA to maximum and use the trick at the same time?

Lots of questions but qll worth it i think :)

so this trick works out of the box for the BenQ xl2411t without using qny .inf trick?
this will work without inf only if u have 3d vision IR emiiter ( http://i.imgur.com/vkysZ.jpg ). inf used for enabling 3D coz this .inf of monitor with embedded 3d vision IR emiiter.

btw how does the lightboost2 realy work?
explore http://marky.com/backlight/

does this trick work for lightboost1 too?
afaik there is only one lightboost technology

is it possible to set AMA to maximum and use the trick at the same time?
dunno. guess no coz many menu options blocked when monitor in 3d mode.

my mate happy with xl2411t+lightboost trick

Yes, there's only one LightBoost technology.
"LightBoost2" is simply shorthand for "3D Vision 2 with LightBoost", as it's good for more than just 3D.
Vega needed to use an INF file to enable LightBoost on his XL2411T without an emitter.

AMA is automatically set to a fixed value internally when LightBoost is enabled, because LightBoost is a strobe backlight that needs to be precisely timed with the response time acceleration technology.

Here's a high speed 480fps (and 1000fps) video
of LightBoost strobe backlight in action:
http://www.youtube.com/watch?v=hD5gjAs1A2s

This video shows how strobing is used to bypass pixel persistence, eliminating motion blur caused by either pixel persistence or eye tracking. Response time acceleration is force-enabled with LightBoost because the pixels need to refresh faster (while in the dark), before the end of the refresh, before backlight strobing, before the next refresh begins.

http://marky.com/backlight/

Amasing work, can lightboost trick be used in 144hz mode? You tested in 120hz i saw. Also on a sidenote it could be awesome to be able to set the AMA lvl independently of the lightboost, it beeing on or off.

@ mdrejhon

"Vega needed to use an INF file to enable LightBoost on his XL2411T without an emitter."

Any chance you know where I can get my hand on that INF file? I order the same monitor yesterday and would want to enable the lightboost trick, but I don't have an 3D emiter.

Thanks in advance

http://www.file-upload.net/download-6944730/A...e.inf.html

Thanks for the link but how come there is an invisible file attached to the INF file you linked to?

That's a nasty habit the file lockers do. Avoid them!

Download this .INF file instead to make a monitor think it's an ASUS VG278H:
http://www.blurbusters.com/files/LightBoost-M...erride.inf
For BENQ, install this via Device Manager.

Then install this .REG registry tweak:
http://www.blurbusters.com/files/ForceLightBo...lasses.reg

Then reboot. Then go to nVidia Control Panel, enable stereoscopic mode. Then this triggers the LightBoost strobe backlight to work properly on VG278HE, BENQ XL2420T, BENQ XL2411T even without 3D, and without shutter glasses.

I've posted detailed instructions:
LightBoost HOWTO: Instructions for Zero Motion Blur on LightBoost LCD's

This is a Windows 7+8 compatible guide for all known LightBoost monitors: ASUS VG278H, ASUS VG278HE, BENQ XL2420T, BENQ XL2411T. No shutter glasses needed!

Does anyone know when 1440p 120hz monitors are likely to come out? I've held out waiting for one, my CRT is on its last legs :/

These monitors kind of suck for me because I work and play from the same PC, so ideally I'd want a 1440p 120hz IPS as my main screen :/

I guess I could get a 1440p IPS as the main screen and have a 1080p 120hz TN for gaming, but I'm not used to multi-monitor setups. I mean if I have the IPS as my main screen, is it easy to load QL and other games on the 120hz screen? Or does it always want to load up on the main screen?

Can't wait for OEL prices to come down :( They seem to be the answer.

For some reason I doubt DVI can push 120 refresh on 2560x1440

It's called overclocking -- there's a way to overclock DVI -- the Catleap 2B users have successfully accomplished 1440p at www.120hz.net

iam planning to buy a new monitor, is this benQ the best considering the input lag?

which one does have the lowest input lag?

Supposedly it has less than half a frame of input lag (<2ms) with Instant mode enabled and at 144hz, and honestly, I doubt you'd feel a difference if it was any lower.

I get these values:

(1/120)/2 = 4ms
(1/144)/2 = 3.5ms

Source: http://pcmonitors.info/reviews/benq-xl2411t

Can't test it myself but I can't imagine it being any more instant than this.

Cant get it working on xl2410T any successful setp by step for this monitor? :)

xl2410t doesnt have lightboost

Well:

I have a 2410t and when I follow nvcs instructions ghosting disappears, the brightness of the monitor changes and some settings in the osd are greyed out.

Are you sure you don't have an XL2411T?
It does, indeed, have LightBoost.

Yes I´m sure.

my mate just tried to enable lightboost on his benq xl2410t and he confimed that there is no any improvement in PixPerAn when monitor in 3d mode. Only darker.

I havent tried it with pixerpan I just dont like it while playing, although there is no ghosting.

Probably because the xl2410t doesn't have lightboost.

haha, that would resolve my problem :D thx :)

Just got this monitor, but is it me or is this extremely bright? I have it on brightness 0 in the OSD, and it is still too bright.

what about the contrast setting?

If you have LightBoost enabled, lower the "LightBoost" setting. It dims the picture. Enable LightBoost first, before doing these adjustments.

***The BENQ XL2411T Crimson Fix
There has been several reports of a crimson color when using LightBoost with a BENQ XL2411T (the new 1ms monitor). This is the solution.

***Via Monitor Menus
Monitor’s Contrast Setting = 65 …. (If using nVidia Gamma 1.10)

***Via nVidia Control Panel – “Adjust Desktop Color Settings”
Adjust them individually, R, G, B.
—
R Contrast = 30%
G Contrast = 45%
B Contrast = 30%
—
R Brightness = 10%
G Brightness = 40%
B Brightness = 10%
—
R,G,B Gamma = 1.10

Make sure to readjust Monitor OSD contrast everytime you change Gamma. nVidia Gamma 1.10 worked best with a monitor OSD Contrast of 65. With these settings, I can see the difference between RGB(0,0,0) and RGB(1,1,1), without a wrongly tinted color in backgrounds or in dim colors.

***Still Too Bright?
LightBoost keeps things bright for 3D, but may make things dimmer for 2D (when not wearing 3D glasses). However, if it is still too bright, then try lower the "LightBoost" setting instead of "Brightness" or "Contrast". It dims the picture. Lowering the "LightBoost" setting (but don't go all the way to "OFF") actually improves motion clarity because of shorter strobe flashes. LightBoost MAX corresponds to 2ms strobes, and LightBoost MIN (not OFF) corresponds to 1.4ms strobes.

Tried those settings, unfortunately they seem to be specific to you, as I found them pretty bad as did Vega.

Loaded up the calibration tool in win7 allowed me to fine tune my reds from there, hopefully there are no disadvantages from doing it via the tool, rather than in Nvidia control panel?

Yep it's really bright, maybe excessively bright. I actually found that doing the lightboost hack above made it a sensible brightness, so it's worth a try doing that.

My second CRT broke 2 days ago ;_;
I'm gonna go for that BenQ xl2411t.

Got the BENQ last night...

Took about an hour to get lightboost working and finally worked out my problem was with my multiple display setup. Very impressive!

I have:

BENQ on Primary DVI Out.
22" 1680x1050 on Secondary DVI Out (60Hz)
22" 1680x1050 on DisplayPort (60Hz)
42" Plasma on HDMI Out.

It's really weird, If I disable two of the screens lightboost works.

I've once been able to enable a 3rd and have 3 working, but not any more its back to 2, and it switches (without cable swapping) which second one it will allow depending on its mood. Have not been able to get 4 working.

Anyone have a similar setup and been able to get it working? Or anyone not been able to get lightboost working and have 3 or more displays?

Emailed Benq/Nvidia & Asus (680), waiting for an answer. Wondered if anyone else has come accross it.

Glad you find it impressive!
Do you see less motion blur with LightBoost than on the plasma?
Are you talking about getting all 4 displays working simultaneously?

Also, do you get any color tinting during LightBoost operation? Some people say they had to use different settings than mine, so I'm wondering if different BENQ's have different LightBoost adjustments.

Is this one better for gaming compared to XL2410T? Due to the specs it is as it has 1ms v 2ms response time, 144hz v 120hz, not sure about input lag tho as some revues say 2410t has just 5.6ms.
But still why if XL2411T seems to be superior then XL2010T its priced cheaper??
P.S. Btw could you spread a word how XL2420T stands compared to those two? From what i learned while briefly browsing about the topic its also decent monitor but mb a bit less suitable for games because it doesnt have that instant mode to reduce input lag. Am i right?

You mean the XL2411T? (24 inch, not 20 inch)
I think it is cheaper because it does not include 3D shutter glasses, and does not have a built-in shutter glasses emitter.

Avoid the XL2410T, that does not have LightBoost, so make sure you get the number eleven (11) -- the model XL2411T.

An uninstall "how to" is missing on your blog man ;)

Yep -- this is on my TODO list.

Generally, it mainly involves uninstalling the INF file, switching back to Generic PnP monitor in Device Manager, turning off the stereoscopic box, and then rebooting the computer. (Uninstalling the registry data is helpful too, though not required unless you have an emitter)

A new 144Hz compatible INF file is also being uploaded by end of February 2013, to make LightBoost much more convenient, simply by switching refresh rates. Switching to 120Hz enables LightBoost, while switching to 144Hz disables LightBoost.

BTW, I've moved all pages from marky.com/backlight to a permanent home at www.blurbusters.com ... Just to be safe, can you edit your earlier posts to point to the new web address, so they are guaranteed to keep working for future readers that come here many months later? Also, the new location of the LightBoost HOWTO is www.blurbusters.com/zero-motion-blur/lightboost/ ... Thanks!

Got it! There's a way to easily turn off without uninstalling. First, verify LightBoost is working by verifying for reduced motion blur, and you've already installed BOTH the .inf and .reg files from http://www.blurbusters.com/zero-motion-blur/lightboost/

TIP: Turning Off The LightBoost Hack Without Uninstalling:

To turn off LightBoost:
1. Turn off the “Enable Stereoscopic 3D” checkbox in nVidia Control Panel
2. Switch to 60 Hz mode, then switch back to 120 Hz (or 144 Hz).
You can use a system tray utility such as MultiRes to do this more quickly.

I just switch to "Only while 3d programs run" in the drop-down before unticking enable stereoscopic 3d. That way it doesn't stay on.

Ye confused a bit with model names. Meant XL2410T and XL2411 ofc.
And about Lightboost is this feature that essential? I mean if the monitor is allready decent right from the stock would you need some extra tools for it that much?

good review and tests of pixel response and input lag:
http://translate.google.com/translate?hl=ru&a...2F27439043
http://translate.google.com/translate?sl=auto...mp;act=url

Interresting, but why do they test it in 120Hz and not 144Hz? And by the way do you know what instant mode does? Also does the picture mode influence latency? On the link they list BenQ at 3.1 ms but they don't say which picture mode.

yeah, their tests make questions but it's better than nothing. instant mode removes big part of input lag.

someone start researching those SLIM CRT's again, yes, they will be wider than LCD, but instafix instead of all this bullshit. Plus no input lag which is a HUGE issue on tvs

Any place I can buy it online and have it shipped over to New Zealand?

Even Clearer LightBoost Motion (but dimmer picture)

New tip if you are a LightBoost user and you want to do both simultaneously:
-- Dim the image a little more (if too bright)
-- Make motion even clearer

Instead of reducing your Contrast or dimming via nVidia Control Panel -- go to your OSD and adjust "LightBoost" setting downwards to 10% (but not "OFF") I've found out that LightBoost adjusted to 10% uses a 1.4 millisecond strobe, while LightBoost adjusted to 100% uses a 2.4 millisecond strobe. A good compromise setting is 40% or 50% if the 10% setting is too dim. This makes LightBoost motion even clearer during ultra-fast motions. Most people cannot tell, but if you are a uber-Elite gamer that need maximum motion clarity, try this!

Also, I've updated the LightBoost HOWTO with a new INF file that now permits 144 Hz non-LightBoost mode. So you can easily switch between 120 Hz LightBoost and 144 Hz NON-LightBoost now.

guys, one important question - what fps do I need for this lightboost technology to work?
what if I have 125 fps instead of 120??? will the image look blurred again?

120 or more will be best
same
no

Anyway to keep lightboost on 24/7 without the stereoscopic 3d driver shit kicking in ?
Even with disabling it with ctrl+t in game, I get a 120fps framelock and some kind of artificial vsync causing massive mouse-lag.
It's fine if I launch the game, then enable lightboost. But the other way around and it's unplayable..

EDIT: Found a fix, just gotta disable the NVIDIA Stereoscopic 3D Driver Service and it won't detect if a game is launched.

just untick "enable stereoscopic" after enabling it. this will disable vsync. guess it's nvidia bug

Do you mean, just unchecking the box and not hitting the Apply button ?
What I did was, pop up lightboost, then go into windows services and kill the nvidia service so it won't detect games. Only problem with this, sometimes when changing resolutions in game, lightboost disable itself for some reason.

I've updated the LightBoost HOWTO with a new tip:

TIP: Improving Convenience, Stability & Eliminating “Control+T”:
Once you’ve verified LightBoost works (Step 12), and the registry tweak was already installed (Step 4), you can make LightBoost “stick” by going to nVidia Control Panel and disabling “Enable Stereoscopic 3D” (clear the checkbox in Step 8). If the screen did not flicker when doing this, LightBoost is still enabled even after disabling 3D!
– Games launch in 2D without needing Control+T
– Driver stability is improved in this mode, less freezing occurs.
- VSYNC OFF now works much more reliably, reducing input lag, fps higher than Hz.
(Note: Some games may automatically switch resolutions; make sure it stays at 120 Hz)

guys I need help... when I try to do it like described in the first linked guide or like in this one: http://forums.overclockers.co.uk/showthread.php?t=18476129

then my problem is 1. when I try to right-click install the .inf, it says "this installation method is not supported for this inf file", and when I try to do it via device manager, it says "the driver for this monitor is already on the latest standing". then when I try to revert the monitor driver to "pnp monitor", it gives the same message.

WAT DO? :(((

I bought this BenQ XL2411T, to replace my crt monitor and so far im disappointed a little with input lag.
First few games my lg tracking got a lot worse, later after getting used this new monitor its still worse by around 10%. I have also checked reaction time on humanbenchmark and i get ~10ms worse results(on both 120 and 144Hz).
Everything else is OK or very good so far.

Unfortunately i have ATI card so i wont be able to use lightboost, but i think that it is not needed anyway because blur is very low and on totally acceptable level.

Well i had a CRT before too and have this monitor now. What i can say is that i was playin 800x600 before and now i use 1920x1080, i had to change all the crosshairs because it realy felt much bigger. I had the sensation cross 2 size 32 was super big in 1080p.

Rly strange as due to most researches XL2411 is TFT with like the lowest possible input lag on the market.having results around 2-3ms from review to review.. Maybe you didnt enable instant mode or smth?

Is anyone else getting a significant increase of input lag with DDC/CI turned on? I have no idea what it does but disabling made a huge difference to latency.

Yep, but i tested it for around 5 mins. I'm going to play some more to be sure that it is not placebo.

I cannot confirm this. I'm unable to tell the difference in a blind test.

Would be great if mdrejhon chimed in on whether or not this is a possibility.

I AM ON NOTEBOOK @ VGA and HDMI.
Any of these 120hz monitors can work 120hz via vga/hdmi?
I know fazz made some viewsonic to work 120hz on lower resolutions..

http://www.hdmi.org/manufacturer/hdmi_1_4/3d.aspx

googled and made conclusion:
maybe you can get 120hz @ vga with lcd with low resolutions, etc 640x480 and 800x600...
No single cable adaptor or notebook docking port will help you.
1.4b hdmi comming (or already here), it can support 120hz with higher res, but as I understood most notebooks and lcds doesn't support 1.4b YET.

exactly
some notebooks got thunderbolt/displayport though which should work with asus monitor

So if I understood, laptop users can't have 120hz on LCD? :/

if they have alienware or some high-end, often they have DVI port, but 99% notebooks have VGA + HDMI ports.

My 6 year old laptop has dual DVI :>

I have a minidisplay port on my laptop so I can plug it directly to my benq xl2420t display port and get 120hz out of the box. Display port on laptops is rare though and I have never heard of DVI on laptops.

I already have the XL2420L and thinking about an update.
Worth the change to XL2411L ?
Is there much a difference between these monitors concerning Input Lag? Cause I only know the XL2411L has around 2-3ms.
Does the XL2420L have around 8ms response time?

Yea this answer im interested in too.

And what about the 27" Benq version like XL2720T?
Or are just the Asus + Acer worth it as 27 edition?

Hi,

I'm currently considering whether to buy the BenQ XL2411T or the ASUS VG248QE.

One of the most appealing aspects of the BenQ XL2411T is the smart scaling feature. All I care about is FPS, so I want 100+ FPS in BF4 to get the most out of the Hz rate.

I assumed Smart Scaling would give better FPS given that the resolution is lower.

I see little talk in forums about the smart scale feature. However, this thread mentions input lag:

Questions:

1. Is the purpose of Smart Scaling to improve FPS performance in games?
2. I've read the manual and seen YouTube reviews and it seems Smart Scaling is set on the monitor side only. This being the case, if the resolution in Windows is still 1920 x 1080, I fail to see how there could be any performance increase. Correct?
3. What happens in games if, say, 19"W (16:10) is set on the monitor, then 1680 x 1050 is set on the GPU – do games look sharp? Could someone test this in BF3 or a similar game?

Thanks in advance,

I think you need to read into what scaling in this case actually is.

Scaling adds delay, its like having less fps, and very blurry image like on all lcd's. Just put graphics lower and always use native res of monitor.

scaling may or may not add a noticeable delay.

Hello everyone,

I have amd system, use lighboost for 2d

After using strobelight from toastyx, my xls411t has "scanlines" @ 120hz, very noticably in lightbost/strobelight, but now I have them also in 120hz non lightboost/strobelight (they weren't before the progrm use, they remain even if I reset the program/unistall it).
Also Ihave got whiter areas/striations/clouds @120 hz non lightboost/strobleight (noticable, but not that much), but in lightbosot/strobelight mode the striations are extreme.
Can anyone test them with a totally black and a dark/gray shade image? Is my monior faulty?

dunno about ur problem. did u try power off display for a minute?

Hello guys, i like this thread because have the same monitor.
I have a question my windows says i have 120hz selected and my nvidia panel says 144hz . pretty weird

Any solution for this? greetings

set native resolution 1920x1080 and set "no scaling" and "Display" at http://i.imgur.com/9yEwiKz.png
may be this will help

Ok so I just got it. Do I still have to install the 3d (stereoscopic) parts of the driver with toastys? (Strobelight.exe says lightboost is enabled)

Also can I use 144 hz in game with this or do I have to use 120?
