Question Is my graphics driver broken or is it the screen itself ?

[seagullrocck]

I recently noticed that the screen of my Acer Nitro 5 2019 laptop has been acting weird. Just below my taskbar, there's a fine black line across the screen that flickers. I tried updating my discrete driver but it didn't do anything. I tried scanning using the command prompt but it said that there wasn't anything wrong.

What should I do? TIA

Could be monitor or gpu failing. Can you try pc with a tv or possibly connect monitor to a console?
