I returned the monitor because 3D was a main selling feature for me and although it does seem to have the electronics for it (it did go into 3D mode) the L/R separation was terrible.

Great color, great resolution; GSync

This monitor is not 3D capable; The bezel is very thin ~3-4mm, but that is irrelevant since the picture does not go right to the bezel; There is a ~10mm border all the way around; They may as well have put a regular bezel on it; The price is way too high considering this feature is missing

Don't buy this ! It's my third one and i have to rma it tomorrow. With all the delays and the waiting for the replacements it's been 30 days and i will probably have to ask a refund and lost the cost of the shipping and the express coverage. 100$ lost....wow. Backlight bleed on all my 3 monitors.

Impossible Backlight Bleed on 3 monitors

Great monitor. Really nice finish and build. Everything works spot on including the 165hz overclocking feature. There is some IPS glow on very dark screens but no back light bleed. This is really an issue with the screen technology.

Great picture quality; GSync works great; Really sturdy stand

Slight IPS glow, only visible on very dark screens; No bleed though

A fantastic gaming monitor that fits both gamers and professionals, but has a steep price tag that's scares away all but those with deep pockets.

I made the move from 1080p TN panel and would now never go back. This monitor is stunning, one of the thinnest bezels I've ever seen, virtually no back light bleed and the g-sync has completely eradicated all of the micro stuttering I often found with my 970 SLI setup.

G -Sync, Nvidia's proprietary frame-smoothing technology, is possibly one of the most exciting game developments in the last five years. Being a hardware solution – as opposed to AMD's similar, but software-based, FreeSync – it does add a bit to the price of a monitor, but when you combine that with...

The Acer Predator XB271HU ($799.99) not only looks identical to its sibling, the Predator XB271HK , but it also delivers outstanding gaming performance and is equipped with many of the same features, including a fully adjustable stand, gamer presets, and Nvdia's G-Sync technology.

Nvidia G-Sync anti-tearing technology; Very good gaming and gray-scale performance; Fast refresh rate; Stylish design

Expensive; Middling color accuracy; Weak speakers; Only two video inputs

The Acer Predator XB271HU ($799.99) not only looks identical to its sibling, the Predator XB271HK ($586.46 at Newegg) , but it also delivers outstanding gaming performance and is equipped with many of the same features, including a fully adjustable stand, gamer presets, and Nvdia's G-Sync technology. But the Acer XB271HK is a 4K gaming monitor that offers better color accuracy than the XB271HU ($459.99 at Amazon) . Even though it costs $100 more, it remains our top pick for large-screen gaming displays. Design and Features On the outside, the XB271HU is indistinguishable from the Acer XB271HK. Both use a sleek, bezel-free, matte-black cabinet and come with a black and red V-shaped stand. The stand provides 5.9 inches of height, 40 degrees of tilt, and 30 degrees of swivel adjustability, and allows you to pivot the cabinet 90 degrees for Portrait-mode viewing. Pressing the quick-release button lets you remove the cabinet from the stand and hang it on a wall using the four VESA mou...

The 27-inch Acer Predator XB271HU offers very good gaming performance, a fully adjustable stand, and lots of style.

Any product that one purchases is in the final analysis only as good as the after sales service. I made the mistake of registering my Monitor with Acer with the thought that if in trouble the Manufacturer is the one to put you right. The, so called, 'owners manual' I found useless.

The Acer Predator XB271HU is one of a new breed of gaming monitors that not only features the high refresh rate you expect of a gaming display but has the great image quality you'd associate with an IPS panel too.

Superb overall image quality; G-Sync eliminates tearing and stutter; 165Hz IPS panel is fantastic for gaming; Good design and build quality

Expensive; Only two inputs; Speakers are weak
