[SOLVED] Monitor randomly goes almost black

[Gripzy]

Hi! I have a BENQ G920WA that randomly goes almost black, like a really low luminosity. If I turn it off and back on, it is ok, but after some seconds it goes almost black again.
This is the video of me turning it on then going at a low luminosity:

Change display cables and see if that works. If your monitor has an external power brick, try swapping it out with a similar one with the same voltage and same or higher amperage. Try updating drivers too.

If those don't work then your monitor is defective internally. Since this model is quite old, you're better off just buying a new monitor.
