[Acer Predator PH315-53] Screen darkens in games

Hello,
First please apologise my poor english.
Since I have my PC (I bought it 6 months ago), i have annoying problems in games (Skyrim, Dark souls 3, Elden Ring and many more)..
When my game is fullscreen, light, clouds, items, textures darkens when I move the camera. I dont think it's a GPU/wrong graphic setting because screen recorders dont "see" it. Here a video of the problem : https://drive.google.com/file/d/10Crj6I_mIQ_dD0wf0U9O7KCSxPEBP9Pl/view?usp=sharing
This problem doesnt occure in borderless.
I've done all Bios updates, my graphics drivers are up to date, I even did a reset.
Could you help me please ?
Thank you,

Hello,
I don't have this option, only "bluelight shield", wich is disabled.
I read that some Asus monitors have the same problem, solved by modifying a setting called "tracefree".
But I cant access any screen setting : I have a laptop
Thank you,
