bright line across the whole screen

[XNexis]

Hey, i just noticed this bright line going over the whole monitor (at the top). It's not visible on screenshots so it has to be the monitor(BenQ XL2411Z). Could someone tell me what caused this and if i can fix it ?

Does the line move or disappear from time to time or is it static on your screen at all times? If that's the case, then try using different inputs to your monitor to isolate the card from the monitor. Most likely, this is a damaged monitor.
