latency is the time it takes for an input to display on the screen. obviously you want it low as possible. to find out you'll have to do some googling on the model you're looking at because they won't say or will lie in their specs.
response time is how fast the monitor can change a pixel's color to another color. a bad response time means ghosting. again you can't trust company specs, it's best to see if someone tested the true response time or to read reviews that say if ghosts or not.
other than that, if you play very demanding games and as a result have lower framerates, look for a monitor with nvidia g-sync
also some monitors will have an optional lightboost or "strobed backlight" mode which almost completely removes motion blur at the cost of some added latency
Any decent Trinitron / Diamondtron has better image quality and colors (more so, if it's calibrated), higher refresh rates with prolly 0 ms input lag, for the 1/10 - 1/15th of the BenQ's price.
...so you intend on using the onboard videocard of the motherboard? you know those are very weak right? ;)
if you are building a new pc then ignore what onboard video options motherboards have, and get a decent videocard with Dual-DVI or DisplayPort (like comrade mentioned)
and no, i dont believe hdmi does high refreshrate. only the new updated hdmi standard does but there are no devices on the market that use it at the moment.
when looking for a gaming monitor, make sure its a TN panel, thats the type of technology used on fast monitors (its the fastest of TN/IPS/VA)
then look for some good reviews mainly concerning contrast and color accuracy. make a decision based on that since all 144hz panels will be fast. i think the most popular monitors are the benq ones though, and perhaps the asus vg248. cant really remember whats supposed to be popular right now, maybe someone else can help with that.. :)
I think people are making a mistake when it comes to G-sync. They expect completely different scenario of what it's suppose to do. Like it will magically make it a CRT. Still I will hold on and see for sure what the first releases do. It shouldn't be long now
from what you can read about it, i expect it to be even better than a CRT at lower FPS games.
you won't gain anything in QL anymore, since it runs with 250fps now, but the usual 144hz shóuld be enough in this case anyway, to forget your old CRT.
Yeah I don't necessarily want g-sync for quake, rather for other games, but a lot of the newer monitors are going to have anti-blur features too.
I went to a quake lan a few weeks ago and the guy I setup next to had a samsung 2233rz, and so compared my 120hz to his, and his looked so so much better. Ironically that was my old monitor! I didn't compare the 2 when I bought the new one. Anyway so sold the new one I got, unfortunately there isn't anything cheap like the 2233rz anymore, but quake at 150hz is pretty sick, so I should be fine for awhile.
On G-Sync, it isn't meant to make it like a crt, in some ways it should be BETTER than a crt, at least when it comes to tearing, smoothness and response time, but that technology won't do anything for blurring, but hey if they get lightboost to work at 1ms, that should be fine.
even the first generation 120 Hz LCDs were 2 ms response time. if you want to see a blurry mess go use an ips/va. any less than 2 ms is just icing on the cake.
I tried this monitor and it is very sharp and responsive but the picture quality is simply awful, it is way too bright and washed out even at the lowest setting and it displays really bad banding/dithering (like many if not all cheap TN panels though). Found several other people who said the same, most of those (like me) bought it after reading the DigitalVersus review (once again it shows how crap DigitalVersus reviews are, 2014 and they still haven't updated their outdated input lag testing which shows completely wrong and useless numbers...)
I could not find settings that looked any decent and the contrast was pretty poor anyway. I have a calibrated IPS panel and while of course I was not expecting it to look the same, I was hoping to get something reasonably close since I've seen plenty of TN panels that look decent. Even my laptop's shitty old TN panel (from 2009) looks okay in comparison despite a really low contrast ratio.
It's an okay monitor for purely competitive gaming maybe but at the same time it's a shame to have no g-sync and no ULMB mode (or similar) at all. Better look at other options with at least ULMB (g-sync adds a HUGE price premium sadly), it won't cost much more.
