Question PC Monitor Problem

[johnbnt]

Hellow,

My pc monitor suddenly, since 2 weeks, started to be very bright when starting and in about 30 minuites is restoring to normal. Its a monitor problem as other monitors are working perfectly in my pc.

What can I do?

Probably is the monitor, something to do with the backlight, or backlight brightness control circuit.

Do you have HDR enabled in Windows, and is it an HDR-enabled screen? I'm guessing no, that it's an older screen.
