Grey Screen

[Nox]

I got an issue with my game, not sure why, but my screen is grey, i mean i can see the game, but there a grey glow on my screen, its like super dark and it basicly unplayable, i can play but its really unconfortable and after couples games my eyes just cant stand it anymore.

Im not sure why it does this, its basicly the first time, i think its relate to my HDR mode, but even if i remove it, it keep doing it since then.

Any can help with that pls.
