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

I upgraded from a Dell 2713hm, mainly because the Predator was on Sale and I had planned to go to 4k anyway. Using two GTX Titan Hydro Coppers to drive it. The Dell looked nice, but this 32 4k looks much better.

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.

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.

When we reviewed Acer's 27-inch Predator XB271HK earlier this year, we were so impressed with its performance and features that we awarded it our Editors' Choice. Acer has another winner on its hands with the Predator XB321HK ($1,299.99), the XB271HK's bigger brother.

Excellent performance; Sharp UHD image quality; Nvidia G-Sync technology; Slick design

Expensive; Two video inputs; Weak speakers

There are some who will quickly dismiss the Predator XB321HK because of its high price. But just how much more does it cost than any other 32-inch Ultra HD monitor? And we have to remember the G-Sync premium, regardless of the screen it's installed in, is around $200 of that cost.

G-Sync; Ultra HD; 32-inch IPS screen; Clarity; Vivid and accurate color; Styling & build quality

No swivel or portrait adjustment; no DisplayPort 1.3

Gaming at 4K often comes at the cost of smoothness, but Acer's hoping to make that trade-off a thing of the past. The company's Predator XB321HK gaming monitor backs up its ultra-HD resolution with Nvidia G-Sync technology, allowing you to play your 4K games without worrying about stutters or screen...

Gorgeous picture quality; Smooth G-Sync performance; Low latency; Powerful audio

Not much articulation; Pricey
