Does anyone know what problem it is ?
In the left corner there is a blue and orange light on a black background

Secondly should I return it or fix it under warranty where I bought it from ? The price increased by 50 euros now, because black friday ended
 
I think, he's talking about those backlight bleed spots at lower left portion of the screen.

What is backlight bleeding?​

Monitor backlight bleeding


A modern monitor basically consists of a panel with pixels and lighting placed behind it, so you can see the pixels. Backlight bleeding occurs when light from your monitor backlight escapes from the edges of the screen. Light that's supposed to shine through the screen now comes out along the edges, resulting in uneven lighting on the screen.
