Dell 2417DG Light Bleed

[Savo.]

I had this monitor, just over a year and then it became faulty. When you switched the monitor on it started flashing different colors and the settings went back to default every time.

So I rang up Dell and organised a replacement to be sent out. But when trying the light bleed test on the new monitor, it has it in the bottom right corner.

I am just wondering should I get it changed or stick with it?
