XG270 Low latency

[xAD3r1ty]

Hello, what's the best settings if we are strictly talking about latency?

Would it be 240hz non strobed
240hz pureXP
224hz non strobed OR
224hz pureXP

Thanks.

Max refresh rate + unlimited fps + no sync of any kind + no strobing + preferably overkill frame rate = lowest possible latency.

I thought the same, but after trying for a while i found purexp 224hz to be much better than no strobe 240hz , 240hz just felt like there was motion blur, and latency was the same

Yes, but don't forget to add the human lag too.



For SOME GAMES (usually not CS:GO), motion blur reduction speeds up human reaction time massively more than the strobe latency. Some champions of some leagues (e.g. Rainbow Six) uses strobing, but then again, strobing is more critical in some games.

To better understand the strobing lag tradeoff versus human reaction time tradeoff, please read:
HOWTO: Using ULMB Beautifully OR Competitively.

Study the thread carefully to understand why strobing is useless in some games, but important in other games.

The mart ones know it's Right Tool for Right Job.

Yeah i agree, purexp at 224hz is just so good i feel like theres no point using 240hz non strobed, i'm pretty sure most people won't tell latency differences, i'm very sensitive to it and i can say i have a really good aim and purexp feels better (motion wise)

The strobe lag difference is actually as little as 0ms for some areas of the screen, and refreshtime for another area of the screen. So average mathematical lag is halftime of 240Hz (~2ms strobe lag penalty).

However, you *can* adjust strobe phase to reduce screen center lag to have as little as 0.5ms strobe lag, if you don't care about crosstalk below the bottom edge.

Strobe latency gradient is a vertical lag gradient from just underneath crosstalk zone to just right above crosstalk zone:





However, there's another factor. Subtracting the pulse width (1ms), that means 75% of a 240Hz refresh cycle may be hidden by eye, but since not all pixels refresh at the same time (www.blurbusters.com/scanout), some pixels will have been freshly refreshed when the screen is flashed, while other pixels will have been refreshed longer ago in the dark period. So you've got halftime of 0.75/240sec instead of halftime of 1/240sec.... as in (drum roll) ~1.5ms strobe lag penalty for a well-tuned screen centre of a 240Hz display.

Monitors that supports Blur Busters Strobe Utility (select models of BenQ ZOWIE, Spectrum, ViewSonic) can let you choose your latency-vs-clarity tradeoff. Now if you're concerned about lowest crosshairs lag (screen exact centre), you want to move the crosstalk zone to right underneath the crosshairs area.



Anyway, the bottom line is that strobing isn't necessarily bad for esports. You just have to configure it correctly to reduce human reaction time by a bigger degree than the strobe latency itself. However, there is also a brightness vs clarity tradeoff, so if you require a brighter picture (not everyone), you also have to adjust the tradeoff (strobe presets which affects the pulse width)

How would you adjust strobe phase to reduce screen center lag to have as little as 0.5ms strobe lag?

Unfortunately, the XG270 does not support strobe phase adjustment. It's best to purchase a monitor that supports Strobe Utility

Sorry for late answer, what about 240hz non strobed at the fastest OD ? With Full color control there-s a lot of ghosting but if i select something else like sRGB the fastest OD at 240hz seems to be fine
