Expert Reviews

What reviewers liked

The Asus ROG Swift PG279Q is the best G-Sync gaming monitor. At 27 inches, this $800 display is a perfect size for immersive gaming without it feeling overwhelming, and its 2560×1440 resolution gives you plenty of desktop space for your work.
The ASUS PG279Q has excellent motion handling. It has a remarkably low response time, thus you can only notice a very slight trail following the image.
Huge refresh rate spectrum
Color accuracy is the same at 165Hz as it is at 60Hz. The blue light filter hurts color accuracy, though the display actually manages a delta error of only 1.5 at the first level of filter, which is still quite good.
The monitor's build quality and features are top-notch; you can really tell that Asus pulled out all the stops on technology and features.
Low blue light and flicker free eye care feature
The monitor has an incredible refresh rate which ensures that you witness the best of the graphics that any video game has to offer. The barrier of 144Hz has been broken by this screen as it offers a refresh rate of 165Hz, which ensures that the user can see smooth graphics and enjoy their gaming session to the fullest.
The monitor is also equipped with NVIDIA’s ULMB (Ultra Low Motion Blur) which via backlight strobing provides a CRT-like motion clarity for better aiming/tracking in first-person shooters.

What reviewers didn't like

The PG279Q uses a power brick instead of the regular three-pin power cord most monitors use. The brick is bulky and annoying to manage if you’re trying to keep the cables under your desk tidy, and the it will be harder to replace if you lose it.
The monitor has a low native contrast ratio so blacks appear gray in a dark room, but good viewing angles so the image remains accurate when viewed from up-close.
Significant light output reduction in ULMB mode
We measured a curve of 2.4, which is off the target of 2.2. Most competitors come in at the ideal 2.2, or at 2.1. Higher numbers represent darker reproduction of grayscale. In practice, this means that images will appear darker than they should. It’s not a huge concern for gamers, but it’ll be a problem for anyone who edits photos, videos, or other digital media, given the monitor provides no option for gamma adjustment.
The edge where the panel meets the bezel combined with the glass has a slight magnifying effect.
G-SYNC will only work on GTX 650 Ti Boost or higher spec graphics cards with DisplayPort output
It is a little bit on the pricey side
Calibration is necessary for the optimal picture quality
