[GUIDE] Disable Nvidia Scaling and reduce Input Lag - Page 2

I have a VG248QE (780Ti; Currenly using FW 344.75 under 7 Sp1) and I cannot manage to get it working either

Due to variables like the Nvidia pixel clock limits, which I haven't really kept up with what they are by default nowadays, and whatever else is hardcoded into Nvidia drivers when it sees refresh rates over 120, you would be more likely to have less issues using 120hz or lower. I figure there must be a reason BenQ themselves recommends using 120hz on their 144hz panels as well.

What about 1hz higher? e.g. 145hz?

better to use a value that divides well into 1000 for 1000hz mouse

1000/144 = 6.944
1000/145 = 6.896

1000/143 = 6.993 (almost exactly 7 polls per refresh, so better)

those values are approx:

91hz (11 polls per refresh)
100hz (exactly 10 polls per refresh)
111hz (9 polls per refresh)
125hz (exactly 8 polls per refresh)
143hz (7 polls per refresh)

they don't line up so well at lower refresh rates, unless you use 50hz for example

i don't know if these screens will take 145hz, or rather what do with custom timings etc to make them work well

nice sig~!

I have been trying this without success. i have the xl2411t. Tested both 119 and 143hz with different timings without luck. I see now that I cant change scaling options at all. I'll call them tomorrow and see what they say.

I just tried this again and it appears to work for me (xl2411t). Make sure you follow every step, 130hz is the highest I can get it to support. I /feel/ like I'm on a much higher DPI when it works, it's strange.

http://www.humanbenchmark.com is good to test the latency of different scallings even when you are in windows.

Yesterday I performed ultra bad in CS:GO when I tried GPU scalling instead of display scalling - because I thought that my GTX 670 would be faster at upscalling 1280x720 than my very old laggy screen.

But this humanbenchmark test showed me, that I perform worse with GPU scalling when I set the windows resolution to 1280x720 and let the GPU scale to the display's native resolution.

It also helps to test different display scallings, like the effect of stretching. My old display is faster when keeping the aspect ratio, than stretching to widescreen.

Now I will test if a native 4:3 custom resolution like 1440x1080 will have least lag.

No idea how I made it out 14 ms lol

This often happens when you preclick with your trigger-happy finger.

I also like to use this site to test the influence of various BIOS settings on input latency.

But always keep in mind that windows uses vsync (with Aero and later versions).
