Review on Sceptre U275W UPT 27-inch 4K DisplayPort Monitor - 3840x2160P, 70Hz, Frameless, Tilt Adjustment, Flicker-Free, Built-In Speakers by Ken Morton

The monitor worked fine for 2 months, then the problems started 10 minutes after turning it on. It starts to pixelate with shadows covering half the screen or more. It's really hard to describe but tech support couldn't figure it out so I was told to send it in for repair. Now the big problem is...I can't watch the monitor for who knows how long...and if I could file it on the warranty claim website I would, but for some reason it doesn't work, which I've tried many times. So I won't dwell on that and just buy a better monitor with a replacement under warranty.
