problem with your back light / inverter need to have it repaired

right click>properties>setting

the adjustment box for colour, brightness and contrast stays fixed on the screen. i tried pressing the exit button.... after a few times it disappears only to reappear within a few minutes. also the auto adjustment option, for which we are supposed to manually press the i button, keeps auto adjusting the screen whenever it feels like it. the box appears right in middle of the screen and is a real nuisance as it blocks out the main portion.

Take it in and have it bench tested. Terry

go to benq.com and download drivers there.

do you have internet connection? you see computer on task bar?

The problem is in the power supply board there is one or two capacitors that open, in some cases it will have slight puff at the top.

It is possible to bridge to another power supply. There are simple tutorials on YT to help and the process is not very invasive, if you do not wish to harm the current bezel. I was unable to find a switch online to match the model number. Maybe try something close enough to match.

If no issue with other inputs, check the compatibility of the frequencies and refresh speeds.
