Display Enlightment by NCX

So i receved my XG2041.

So about pixel inversion/scan line/ interlaced pattern artifacts, i dont notice them

But i encounter a problem that i didnt have when testing other TN monitor
I have, at the bottom right corner and half low right edge of the screen, a kind of glow or reflection. It is only visible on dark content and of course, i followed your post on correct viewing position

The glow disappear if i move my head to the right, and black doesnt look anymore different than the rest of the screen

Pcmonitor.info mentionned TN Glow if user is viewing at sharpers angles or off center viewing angle, which wasn't my case

So could it be a defect in the product or bad black uniformity ?
