bright problems

[root2]

Hi everyone;
I have update my video drivers, and now every time I switch

windows, bright changes as an autometic adjustment, some times

bright is too low, so I can´t even read text on window.
How I can quit or remove this auto adjust option ? I´ve search

even on Bios but no success.
Thanks in advance for your help and advice.

Best regards.

You might want to check the GPU settings and see if there's any power saving options. If so, disable it.
