At 32", 4K and Gsync, this is a great monitor. I'm very pleased. Keep in mind that if you have to spend a lot of time at lower resolutions, you're going to notice image quality degradation because this thing is too big for 1080 resolution.

This is a great monitor; Almost no problems with it whatsoever; Color and contrast are great, image is great; Gsync makes gaming flawless; Movies are amazing

- Some issues switching between inputs if both cables are plugged in (hdmi and dp); I haven't figured out if this is due to the monitor or the gpu; - HDMI 1.4; 2.0 would be better to support hdcp 2.2

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.

Great monitor, would recommend. At time of purchase there was not another monitor with G-sync, 32 inches in size AND 4k. Research G-sync if you haven't already, I think it's worth it.

-4k; -G-sync; -32 inches

-built-in speakers are not good at all; but if you're spending this much money on a monitor; you probably have your own

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.

I bought this display just before Christmas in December 2017. I did not see all of the reviews concerning issues with flickering that people claim ACER is not addressing. All I can say is that in the short time I have had it, it is a beautiful crisp display. Plays games great with GSync.

Fantastic quality; true gamers monitor

Only small gripe is the price; for same price you can buy a 55 inch 4K television; and the speakers are terrible

I upgraded to this from a rather poor 23.2" TN monitor dual-screened with a 19" 4:3. Boy what an upgrade. I was like a kid on Christmas morning when DPD delivered it. For gaming, I knew it was going to be a struggle for the GTX 680 to cope with modern 4K gaming.
