Review on AOC U2790VQ – 4K Frameless DisplayPort Monitor with Tilt Adjustment, Wall Mount, Blue Light Filter by Cameron Harris

Brightness drops sharply on the left and right sides of the display (observed on two devices) at or near maximum brightness. This leaves the center as a bright spot. One unit arrived with faint but visible horizontal lines on the display that didn't appear to be from delivery (the panel itself is fully intact). Too bad because the colors are fantastic and the price was very right. I will be going back and replacing with ProArt to complement my ten year old PA248 (which doesn't have bad brightness uniformity or lines in the display).
