  • Windows with colorControl still makes me eye strain

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 How did you got to a situation to not get any eye strain on windows 11?

          I dont really know. huawei d16 also is 2021y model, as your dell 5560, and orient for win10 pre-installed.

          Zephyrus g16 2022 12700h + rtx4060/IRIS XE with last win11 - eye-strain. Was not able to run win10 1809 correctly (power plans + battery draw, hotkeys OSD)

          Thinkbook 16+ 2024 + intel Arc with last win11 - eye-strain. Was not able to run win10 1809 correctly (power plans + battery draw, hotkeys OSD)

          Asus gl702vm 2017 + gtx1060 with win10 1809 LTSC - no problems

          2 workstations (rtx2070s, rtx3080, 3080ti) with win10 1809 LTSC - no problems until I installed any win10/11 above 2004 with any nvidia drivers (old, newest)

              simplex do you really think it’s related to the year of the release of the laptop?

              Do you know how to stop updates in windows?

              Also, the PC I have is from 2021 with i9 10900F and Gigabyte Z490M GAMING X as motherboard,so according to your theory, it should work fine with win11 no?

                  twomee Do you know how to stop updates in windows?

                  google knows: using gpedit.msc, using win tweakers etc

                  twomee so according to your theory

                  my quote: noticed, w10 2004 and up with rtx30+ series gives me pain in temples after 2+ hour of usage

                  twomee it’s related

                  its related to this and supported/nonsupported hardware

                        twomee enable dithering

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

                            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?

                                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)

                                    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

                                      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

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

                                            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?

                                                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

                                                  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

                                                    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?

                                                        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
