AGI It looks like the recovery of the system occurred only partially and not in a clean manner. I am given the option to undo the restore and I may take it after playing around a bit more and checking whether the system has become smoother on my eyes or not.
I should mention that prior to doing the system restore I scanned all the programs and drivers that could be affected. The list was infinitely long. There were so many recent updates of drivers of any sort that I was completely oblivious of, including from HP and NVIDIA.

I undid the restore and the screen still hurt badly. Meanwhile I noticed that the BIOS version had changed, and in the past I had had issues after a BIOS update. I downgraded the BIOS to the last version that did not give me issues, and my laptop is again usable. Next I will progressively kick in updates one by one. I expect the BIOS version to change when installing certain update packages. If that happens, I will restore the old BIOS version and see if I can keep up with new OS builds / versions.

    Hi guys, news about Windows 11 best version for eyes.

    I still use 22h1 and It's ok for me

    For the record; I just have a small separate pc with Win11 22H2 Insider with all updates, but this pc Im connecting to my main pc (Win10 22H2 with all updates) via a capture card, which is an Avermedia Live Gamer Extreme G550.

    Im not sure if this method is producing a better environment for the eyes, but personally so far I can tell I don't have any problems (I have problems with new displays and games with the ominous glowing/focusing produced strains).

    What I'd like to tell is if you have the opportunity to experiment with such HW trials, give it a try, maybe it can help.

    Best for all of you.

    glvn Hello! I am here for all the same reasons - eye strain and other stuff. Bafore 2023 never experienced anything similar. In March 23 bought MacBook Pro 14 and sold it in two weeks because it was horrible for my eyes. Now I am on old Lenovo Carbon X1 Gen 5. Bought a new one Lenovo Carbon X1 Gen 10 beacause my old one became slow. After some work on it (Win 11) i found that I have the same symptoms. Installed Ubuntu on it - the same.

    I restored laptop to factory defaults and gave it a pause. Yesterday I started again but all the time I was surfing through UEFI BIOS and did not installed any OS!

    And I found your 10 question "Do you have any discomfort in UEFI BIOS screen ? (not in OS)". So I am in this case - I feel the same symptoms as in last MacOS (Ventura), last Ubuntu, Win 11 and UEFI BIOS without OS. Is it pointing to something new about OS or cartain laptop or something else?

    Thank you

        recye That would indicate hardware triggering your issue not software

        Our issues can be triggered by hardware, software, or both

            ensete But when UEFI BIOS is "showing me" something (like menus, lists and other options) it is also done by some kind of low level software, mayby some unified display driver. When I connect external displays (i have got two of them) to my old lenovo - everything is OK, but when I connect them to a new Lenovo - i have eye strain. External monitors are the same

                recye Some folks believe on here that the motherboard could be at fault, perhaps by always dithering.

                Did you try ditherig?

                Are you interested in empirical research by using a lossless capture card + VideoDiff?

                    sad but true 🙁

                    now I can only confirm the effect of dithering 1.11 on desktop intel hd630 (windows 7)

                    try on linux: "% sudo intel_reg_write 0x70008 0xc0000040 # no dither"

                    does your lenovo carbon x1 gen 5 have hd530 or hd630?

                      ryans Did you try ditherig?

                      Have you tried it? I have been hearing about this for long, but never understood if it kills it or it is the nth potential fix that works only for someone and only for two days and then the eyestsrain is back...

                          Hi, it is not clear from the above posts…. have you figured out how to revert the changes that get installed after the 22H2 update? I installed it 2 weeks back, it was only the 22H2 update, but uninstalling this feature update AND reverting to a restore point right before this update was unable to remove eye strain I'm now getting with that PC…

                              machala The restore point thing has never worked for me. It has always incurred errors and left the system unstable, so I dropped it. Instead I used the Control Panel to uninstall all the updates until the OS would return to the last good version and build. However, this has stopped working too and I haven been in pain for the past few months even with 21H2 and a build that used to be good. What has irreversibly changed is the OS Experience. I think that's due to the service stacking updates that cannot be uninstalled, at least via the Control Panel. I tried to find out what a service stacking update effectively does, but I couldn't learn anything from the web.

                              One last note about the restore point. There's a functionally that allows to check all that has changed between OS as per restore point and OS post-security updates/service stacking updates. I ran the check once and the list of all the edits to the system was infinitely long, including drivers.
                              Unfortunately I cannot wipe everything off and reinstall Windows as it is a business laptop and I am already "illegally" downgrading updates for what is possible.
