The screen works great, aside from the 1-3 times a day when a blob of vertically oriented colors ripples across a section of the screen. I have two of these and one does indeed have the vertical tearing issue so many others have mentioned.

This monitor have great 4K display however if you bother about backlight bleeding then be aware that I had excessive one which was really annoying when you have dark scene. I know IPS panels are suffering with this issue a lot but I can't accept in that level.
