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

I bought 5 of these monitors in 2020 in a few months. For the first 6-18 months I have 1-2 red or blue vertical lines on the right third of 4 out of 5 monitors. It is very difficult to contact customer service to have a repaired monitor shipped to you and you need to make sure you see and report it before the first year (12 months) of the warranty expires. Aside from a few nasty lines due to stuck pixels, the monitors are good and otherwise well priced for standard 4k.
