  • Dithering Disabled, Flicker Free Monitor… Still Dizzy

Hello all,

I have the following desktop setup:

ASRock H81 PRO BTC R2.0 LGA 1150 Intel H81 HDMI SATA 6Gb/s ATX Intel Cryptocurrency Mining Motherboard

Intel Pentium G3260 - Pentium Haswell Dual-Core 3.3 GHz LGA 1150 Desktop Processor - BX80646G3260

G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin PC RAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL10D-16GBXL

eVGA Nvidia 1060 GTX 6GB Video Card

ASUS VG248QG 24" G-SYNC Gaming Monitor 165Hz 1080p 0.5ms Eye Care with DP HDMI DVI,Black

Windows 10 Enterprise LTSC 21H2

The monitor is set to use G-Sync and 60hz because a higher hz really irritates me (crazy headaches and lower legs go numb).

I used Color Control to disable Nvidia Dithering

I have the ICC Profile from Asus for my “flicker free” monitor.

I have set the ASUS Monitor to sRGB mode. I have also tried brightness at 100% with f.lux

Despite all these, I get immediate strain and headaches. What can I be missing? Can motherboards emit some sort of weird frequency? Maybe the monitor has some black color off per rtings.com?

Thank you,

K.

    Boot linux and see if that helps. Use Fedora Xfce spin, Debian live xfce, or Xubuntu.

    You will have to turn everything off and slowly enable things as you go. I would pull out the nvidia card and switch over iGPU.

    Turn off every single feature in your monitor especially if it's for gaming e.g. BFI, VRR, etc:

    To me the monitor doesn't look flicker free based on rtings test at 100% and 0%. 50% might be okay but the resolution that they provide is too poor.

      moonpie have you had better luck with xcfe over gnome in terms of comfort?

        Disable

        Dizzy G-Sync

        and

        Dizzy ICC Profile

        Also try to set monitor in default profile instead of

        Dizzy sRGB mode

        Also not sure 60hz in your high freq monitors are safer than 165hz. Try to use 165hz, or you sure for 100%, 60 is better?

        Dizzy I used Color Control to disable Nvidia Dithering

        Which another driver config you tweaked? dithering disabled by default in 8-bit + fullrange signal

        And finally, try nvidia 545.84, with default settings. Does it detect your monitor as 8bit + fullrange?

          simplex Thank you. I will try those things. Even before these changes it was really bad upping the hz. It is showing as 8bit. I also found per rtings.com that my monitor has bad black uniformity.

            Dizzy I will try those things

            Recently I had to reinstall win10 to my safe FHD 60hz asus laptop, and found next things:

            1. G-sync activated gives me strain
            2. Display profile gives me strain
            3. windows "Night mode" doesnt matter in terms of eye-strain
            4. You can also try a bit older nvidia driver, which is also good - 451.67 ( only display driver, with checkbox "clean" install )
            5. I also tried last win10 22h2 and it was good but a bit slower in my 2017y laptop ( this last win10 is good in modern miniPC ), so I installed good one win10 enterprise LTSC 1809 17763.1098 which is fast and strain free
            6. If steps above didnt help you, the issue could be monitor. At least my gtx1060 is very calm compared to rtx and newer series

              simplex Thank you. I am strongly suspecting the monitor given the black uniformity. I can see the cloudiness of the screen pretty clearly (especially when it’s a all black screen)

              jordan Yes.

              Gnome = wayland by default now = GPU rendering
              Xfce = Xorg forever = disable compositor and no gpu rendering + xorg allows easy modification

              It's less xfce and more Xorg. You can use openbox, sway, icewm, etc. Yes you can use xorg with gnome; however, it won't be around forever and most don't know how to switch to it.
