Hi, I have a PC with nvidia graphics card, RTX 3060, which connected to external screen, gigabyte M34WQ. i have a dual boot, the first is pop os Linux and the second is windows 11. In the pop os Linux, somehow I got a situation which I don’t have an eye strain. In the windows 11, I tried with color control to disable dithering and although it writes that dithering is disabled, I still have a serious eye strain. Also, I had a windows laptop with windows 11 and somehow I succeeded to work with him without any eye strain with my external screen and with simple external screen of dell at the work. So I t’s not the screen because I have some success to work with without eye strain. Also, it’s not the WDDM of windows because I succeeded to work with the windows laptop without changing any driver. My question is, what makes me eye strain on windows 11 even the dithering is off? How can I check what cause it to me?

For the beginnin, we need to compare data. Whats your current win verison ( pro, home, 23h2 or 20h1, build number ). For win11 - does VRR, AutoColorMode activated, whats is graphic settings (10 bit, 8 bit, full or limited range in nvidia control panel, what is driver version) And secondary, same but for your working laptop (CPU name, grapfic card name (incl iGPU), perhabs display model name, and all window version data as I wrote above)

simplex ohh unfortunately I don’t have anymore this laptop… the details of my windows PC still relevant?

twomee yep. The problem is in windows version & hardware. Or do you prefer to use tarot cards to get answers? 🙂

simplex i wish tarot cards could solve my problem 🙂 i have windows 11 pro 22H2 with build 22621.3296. i dont see VRR or AutoColorMode in my settings so i assume it disabled. i have 8 bit, with full range and the driver version of nvidia is 551.61. the laptop i had, was in the latest of windows 11 22H2, so i believe maybe i can solve it by some tweak in the settings.

@twomee maybe you can try this tool too, it has an option to disable dithering for Nvidia cards: https://github.com/ledoge/novideo_srgb

twomee i dont see VRR or AutoColorMode in my settings so i assume it disabled. its in advanced Display tab You can compress SSD to get extra Disk (100gb is enough) and install 3rd OS: w10 LTSC 1809 (turn off updates) and nvidia 466.63 drivers. Good to know you already used 8 bit and fullrange! I noticed, w10 2004 and up with rtx30+ series gives me pain in temples after 2+ hour of usage btw, what was your laptop config...? Some old hardware dont support windows dithering, so you can use newest win without issues

Hunter20 i tried it too in addition to control color but seems it didnt helped, but thanks for the suggestion! simplex thanks, i will try that windows, need to find a time to that. i wish i could use the latest windows 11 version, sometimes in the work i need to use windows 11 and thought maybe i will figure out what cause it to me besides dithering. i read here about the 8 bit with full-range, i understood that the limit color and 10 or 6 bit enable dithering. the laptop was new, it was a Dell, i think the model was precision 5560 with nvidia card. which old hardware doenst support dithering?

twomee huawei d16 2021, ryzen 4600h based, win11home for 1 language, 22h2 19045.4046 installed - no problems at all ( iGPU driver config dont affect on dithering )

twomee could you pls type all spec of dell…? its important thing

simplex this is the laptop: https://www.pcmag.com/reviews/dell-precision-5560 How did you got to a situation to not get any eye strain on windows 11? I also have a thinkpad T470 with iGPU(intel 6th) without graphic card and I didn’t succeed to solve it.

Windows with colorControl still makes me eye strain

simplex i found this build:
Windows 10 1809 LTSC 17763.1075
is that ok?
all version below 17763.1098 is that ok? 17763.914, 17763.832, 17763.1075
also, from where you downloaded it? do you have a link?

jordan

twomee

Install the older one and then install the manual 1098 update

simplex

1809 LTSC 17763.1098, next 2 CPU updates (kb4589208

Are you using an integrated Intel video card or a discrete one? in situations where eye-strain is affected kb4589208.
What version of CPU microcode is currently running on your system(and CPU model)? (kb4589208 is update microcode to 0xCA on Coffee Lake system, for example)

simplex

glvn Are you using an integrated

Intel Arc iGPU @ ultra CPU. Win10 support Ultra only with 20h2 and later (after 2 KB updates in 1809, I got 1 socket and 1.4ghz base freq instead of 2 sockets and 3ghz base freq at non-strain 17763.1098). Power draw also reduced from 19w to ~12w after those 2 KB's

twomee

jordan do you know from where i can find an old version? I can’t find one

simplex

Finally, in theory, when we get supported CPU (and iGPU) by windows, it starts to dither. In my asus 7300hq + gtx1060 laptop (with w10 1809), dithering by ColorControl is always on, moreover, I changed 2x2 spatial to 1xspatial and finally it change but still dont affect eye-strain. I can disable dithering at all but wallpaper on desktop become full of squares. p.s. same actions at newest win10/11 starting from 2004 (20h1) not affect on final system dithering

twomee

simplex but in my PC i see in the color control that the dithering is off and still have eye strain.

Did you meant that even it wrote is off it’s still on?

jordan

twomee someone has it posted here
https://drive.massgrave.dev/en_windows_10_iot_enterprise_ltsc_2019_x64_dvd_a1aa819f.iso

jordan

twomee it can still be enabled by the OS or GPU it's self or driver. You may also want to try an older driver version if 1809 alone doesn't help. I will say 1809 1098 has been good for people tho

simplex

twomee dithering is off

graphic card's dithering is OFF. but lets name that "windows dithering" is ON. Idk how to turn it off, thats why 1809 is my rescuer

I have an RTX A4000 (based on RTX 3070) and measured its output with a lossless capture card in Bios (no dithering by default) and with dithering disabled in Color Control (no dithering picked up either in Windows) but its still doing some type of dithering that cant be picked up by a capture card as the colors look very over exaggerated/noisier than all my other GPU's. I also tested this very thoroughly on builds 1809: 17763.1098, 17763.107, and 17763.55 and it was still unusable. So far i havent seen a single success story with any Ampere cards based on the GA104 https://www.techpowerup.com/gpu-specs/nvidia-ga104.g964

simplex

build number very important: windows 10 1809 LTSC 17763.1098, next 2 CPU updates (kb4589208 and kb5035849) will give you eye-strain back

Sorry for asking again, but does installing just one update kb4589208 cause eye-strain problems?
kb4589208 a very simple update and actually only contains a microcode update for the CPU. It would be useful to clarify whether the processor microcode version is related to the eye-strain problem

Or does the eye-strain problem only occur when two updates (kb4589208 and kb5035849) are combined?

simplex

glvn Sorry for asking again

I dont know. I found ~5..7pcs of installed KB, after learning what they do, decided to remove this 2

Yesterday I tried to use win10 22h2 19045.4046, so today I "relax" with good devices and headache lol

ensete

FYI I suspect KB5034763 also brings back eye strain

simplex

Jack it was still unusable

unusable to use, or to detect?

here is comparison I recorded using same build but different OS -> https://filetransfer.io/data-package/NG8yC6mK#link

Jack

simplex Unusable as in causes too much strain to use, before testing specific 1809 builds i tested 2004/20H2/21H2 and several Linux distros, all of them with the A4000 displayed an unpleasant exaggerated/noisier image. When using the Turing based Quadro RTX 4000 which is basically just a RTX 2070 i can use this without problems on Linux and 1809 with no strain just like my old Quadro K4200.

simplex

Jack

I got you, looks like GA104 issue

My rtx3080 and rtx3080ti are GA102 LHR based chip, no issues in w10 1809. Rtx 2070s is TU104 chip, also OK.

Your Quadro RTX 4000 setup also unusable in win newer than 1809 (havent tested 1903), or you found something more to use?

twomee

Well, I tried the windows version you mentioned here and from the installation screen I felt a relief in the eyes. But my problem is I need windows 11 for latest updates for games, some programs which requires 11 version and so on. I feel that the install of windows 10 is not a fully solution, we need to find a way to use windows 11, to disable windows dithering

simplex

twomee

exact build I wrote above?

I am in same position: my laptop need modern OS, my software need GPU acceleration introduced in win10 2004+

jordan

twomee maybe we can pay someone on Fiverr to reverse it and find a way to disable it all

twomee

simplex this build

https://drive.massgrave.dev/en_windows_10_iot_enterprise_ltsc_2019_x64_dvd_a1aa819f.iso

so how we going to solve it?

simplex

twomee

type and execute winver in windows search panel to get build

Personally I have been searching from sep23

jordan

twomee some people on led eye strain telegram group have said 4070ti strix on win11 is fine for them. I'm still wondering if it really is or if they aren't as sensitive to the OS stuff
