1, LED panels are also LCD panels, it's the type of backlight what differs.
2, Response time != input lag. If you have 120fps (which you don't with your 750ti), you are good with 8ms (1000/120=8.333333333333333).
your math is wrong, i have a 1ms monitor and the other is 5ms, and there is a big difference with mouse trails and dragging around aero windows on your desktop, which you can obviously move alot faster then most games will be running
LED panels arn't just LCD panels, LED's can update and refresh alot faster then LCD's, OLED is the new backlight panel which is suppose to give you richer colors and cheaper then IPS panels
no, back in 2010 there were just LED LCD's were the LED were the back light, a few years later came something new, which improved all the viewing angles which went upto 170 degrees before loosing the image instead of 40 degress like normal LCD panels have
OLED has no backlight, every pixel is lit independently.
it is not cheaper, it is far more expensive than LCD.
LCD and LCD with LED backlight are the same technology with different backlight. you could replace the backlight on an old monitor with LED backlight and it would do absolutely nothing for the lag because it has nothing do with the matrix itself.
There a lots of different type of LED backlights
- edge lit (mostly used in "gaming" monitors and usually (while it produces more blacks) even worse than a properly made ccfl panel (From NEC for example)
- Full array white LED backlight
- panels with the ability to dimm areas localy
- True FULL RGB LED panel (very expensive, three (RGB) leds at each position)
- etc
These above only have a little connection to input lag, really (for example, I think Phillips had a panel which was 4ms fast and still had 100ms inputlag at the same time).
Some of the things you wrote doesn't even make much sense tbh, but thats ok, we still need you.
input lag will always be atleast 2ms, 1ms for usb port if you actually have a single port usb host, then a few nano seconds, then the 1ms to update your monitor
modern LED's panels don't have no ghosting or any of the rubbish from old LCD panels, so why bother with a rubbish CRT
Modern LED LCD panels have blur, even with Lightboost, unless you go with TN panels which are something I would never touch.
No IPS or PLS panel can pass the 120Hz blur tests at this moment, the text is only readable on CRT displays.
(btw, I don't really mind the blur if there is no overshoot (what you don't really get on good monitors), I actually like it as a "screen space motion blur" effect in games).
I think you should read a little about backlights, I recommend tftcentral, prad, or blurbusters:
blurbusters is full of shit, blur is caused by panels and LED refresh rates, and having the color up to much on the monitor so you see colors that are nothing like those in the real world, but the middleclass love their TV's to be like anyway
