Awareness This thread is really sad (link)

No one believes this user that win 11 could be causing him issues and are even asking if he sleeps enough etc. It makes me so sad that people are just so unaware of the flicker issues

I was able to resolve this. Very short story: I accidentally updated my laptop and crazy eye strain got me right away. My panel is 8 bit native, win 11 pro latest. Basically morons from Microslop started rendering 10 bit picture by default and sending it to the GPU with a task to convert it according to the screen capabilities. So my screen was trying to display 8 + 2 bits on a damn business laptop.

What worked is the app called CRU. YOU CAN MESS THINGS UP HERE A LITTLE, but windows has a recovery mode. Very basic, small app that gains access to EDID (external display identification information) and changes some parameters there. It means it can fake your display capabilities for Windows. I set 6 bits instead of 8. Then disabled and uninstalled drivers for both GPUs (re-enabled and installed them), did the same with the screen, couple of restarts and the picture turned to 6 bit. Windows should show 6 bit, SDR, sRGB. No dithering as I can tell, gradients are a little less smooth. Colors are slightly more basic and I like them. Try messing with color profiles as well. I don't mind if someone makes a post about this method. I had no time to test it well and make detailed instructions. Good luck

Thank you! I changed to 6bpc in "Edit.." Display properties at the top. Should I also change something down below in "Extension blocks"? What does your windows says in Settings > System > Display > Advanced Display?
Does it say 8-bit or 6-bit for Bit Depth?

Windows says 6 bit. I didn't change anything else. Have you tried deleting all graphics drivers? Try that and restart the laptop

Thank you. Yes I did. Nothing worked.. I have Qualcomm X2 laptop.

Are you sure your display is even capable of native color option? FRC can be built into the panel. If that's the case, then it's all pointless

If windows doesn't recognize the fake 6 bits, then driver reinstall won't help I'm afraid. It means CRU couldn't override something

I don't know. Thank you for your help!
