“The uniformity on that M28U and the 28" panels like it is absolutely terrible. Even rtings' review shows a pink hue on the left side. I'd avoid those.”— Osoromnibus on Reddit

“I bought m28u this year and it has a problem with the screen resetting randomly leaving me with a black screen for around 10-20 seconds which is aweful while gaming. I looked online and it appears to be a common problem (search gigabyte m28u black screen). I tried all suggestions to fix, including buying 4 different HDMI cables which was what gigatech suppor”— Elegant_Cancel on Reddit
“I had one of these and retuned it. Horrific uniformity. Really bad dirty screen effect and had two bright lines from top to bottom on a white screen. Also, the overshoot at 60fps was intense”— Bjmort on Reddit

“well it seems pretty good except one dead pixel on the lower part of the screen. I don't know...I'm still on the fence”— Labrys67 on Reddit
