Hi all
Trying here out of desperation to perhaps get some suggestions.

My GPU broke down, so I bought a new computer to game from. I also have a work laptop I connect with a dockingstation to the same dual screen setup.

The old computer and the worklaptop give no issues at all. I can/could use them 15 hours a day no problem with exact same screen setup and have for many years.

New one I instantly feel something is wrong and get tired eyes, headache and nausea - especially bad the days after. It seems to be both when using desktop and when gaming though especially after hours of gaming.

Old computer was self made using gtx770 and i5 (3rd gen) running win10. Work laptop is ThinkPad t470s.

Computer giving issues is running i5 (10th gen), GTX 1660 super and win10. Full specs here ( less ram tho) https://geekd.dk/products/lenovo-gaming-g5-14imb05-90n9

It is insanely frustrating since i basically wasted my money and have no way to guarantee buying something else will work.

If anyone has any specific setting or other suggestions then it would be very much appreciated.

Hi NebulT3,

Based on your experience I imagine you are sensitive to temporal dithering. Its a layer of moving static applied to your graphics output to fake deeper colours and smoother gradients. As you can imagine, staring at a fuzzy screen for a long time can put a lot of stress on our brains, which has to process that fuzzy screen into what we see. If your laptop uses intel integrated graphics it will use spatial dithering, which is still a layer of static, but it doesn't change so is much less of a problem. Your old GTX 770 will have probably used temporal dithering, though perhaps in a way that affected you less for a few possible reasons.

The good news is you can kind of test this, and hopefully make your PC useable again. If you install Linux, you'll have the option to disable dithering entirely through the Linux Nvidia driver. There is also a good chance that one of the colour settings in the windows Nvidia control panel will disable dithering. I've tested a few Nvidia GPUs, and there is often zero dithering in one of the settings, say limited RGB for my GTX660, or one of the other options. Unfortunately, you'll have no way of knowing which, if any, are better without trying them all out. Personally, I'd try Linux first as you can easily turn dithering on and off and see if that helps your symptoms. Then you'll at least know the cause even if you don't care to use Linux long term.
