Is something wrong with my 1 month old monitor. It was on screen saver for couple of hours, then i noticed the black shade at corner as per picture, i tried restarting monitor is also same. But after like 15 minutes, while i playing with different document color on screen, it appears gone.

Wondering if this is a norm.

For Dell-level quality, that does not look normal

Ask dell to check lo.

Me unluck 2 year ++ dell U 2417 got 3 horizontal line.

Been trying to re-replicate the issue but cant, guess there's no calling dell until it resurface
