The ASUS PG279QZ is a very good 144Hz gaming monitor with a 1440p IPS panel and decent picture quality. It can't reach very high levels of brightness so it is more suitable for an average bright room. It has a low contrast ratio that does not allow it to display deep blacks in a dark room, but the viewing angles are good so the sides of the screen remain accurate when looking from up-close. It has excellent motion handling with a very fast pixel response time, an extremely low input lag and supports G-Sync. All these features constitute an excellent gaming monitor.

This is a newer version of the ASUS ROG PG279Q.

The design of the ASUS PG279QZ is very good. It is identical to the design of the ASUS ROG PG279Q. The stand is plain and supports the monitor well and the ergonomics are great allowing you to position the monitor comfortably with ease. The build quality is very good and even though it is mostly made out of plastic, you should have no issues with it. It has thin borders and a clean back with good cable management. Just like the ASUS ROG Swift PG279Q, the base of the monitor can light up with LEDs, as seen here.

Note: The minor differences in the physical measurements of this monitor vs. the ASUS ROG PG279Q can be attributed to small variation in the design measurements.

12.3" (31.2 cm)
9.4" (23.9 cm)

The stand of the ASUS PG279QZ supports the monitor well, but it will wobble a little if you knock it gently. It is identical to the stand of the PG279Q and its base can also light up with red LEDs, as shown here. However, the metal contact that allows the light to turn on only works when the monitor is in a fully landscape or a fully portrait mode.

Height Adjustment
4.7" (11.9 cm)
Switch portrait/landscape Yes
Swivel Range -60° to 60°
Tilt Range -20° to 5°

Great ergonomics. Just like the PG279Q, you can position it to your liking with ease. It allows you to tilt, swivel, rotate and adjust its height.

Wall Mount VESA 100x100

The back of the monitor is plain and made out of plastic. The two large groves, found on each side, serve as vents to dissipate the heat, and the opening found on the stand helps with cable management as seen here.

0.6" (1.5 cm)

The borders of the monitor are relatively thin with a textured finish and a very thin bezel. Just like in the PQ279Q, there is a small gap between the monitor's edge and where the screen starts.

Thickness (with stand)
7.9" (20.1 cm)
Thickness (without stand)
2.5" (6.4 cm)

The monitor without the stand is of average thickness and will not protrude much if VESA mounted. However, when attached to its stand the entire setup looks relatively thick.

Build Quality

The build quality of the monitor is good without any gaps or loose ends, and the monitor feels very sturdy. It is the same build quality as the ASUS PG279Q. You should have no issues with this monitor.

The overall SDR peak brightness is decent. The real scene measurement is slightly lower than the measurements on our preset size windows but this is normal due to the screens uniformity. Unfortunately, the monitor cannot get as bright as the PG279Q and its brightness is closer to the levels of the Dell U3818D. The tests were done using the 'FPS' (calibrated) Picture Mode.

Excellent gray uniformity for the ASUS PG279QZ. In the 50% gray test picture, the two sides are slightly darker, but no other major issue or much Dirty Screen Effect (DSE) can be noticed. The uniformity is even better in the 5% gray test picture, and almost no DSE was depicted by our test. Again this result is very similar to LG 27UD68P-B.

Out of the box, the color accuracy of the ASUS PG279QZ is good. The most accurate Picture Mode is the 'FPS'.

The color temperature is a little warmer than our desired 6500K. The white balance dE is below 3 so most people will not notice the gray inaccuracies, but the color dE is above 3 and thus most enthusiasts will notice some color errors. As for the gamma, the average value is below the target of 2.2 and it does not follow the target curve closely. Most of the scenes will look slightly brighter than they should be.

The Asus PG279QZ has an excellent accuracy after calibration, which was also done on the 'FPS' Picture Mode. The while balance dE was brought down to levels where it is almost impossible to spot any inaccuracies whereas the color dE was lowered below the threshold of 3 so only a few people might notice any color inaccuracies. The color temperature was brought closer to the 6500K target and gamma follows the target curve more closely with an average value of 2.18.

You can download our ICC profile calibration here. This is provided for reference only and should not be used, as the calibration values vary per individual unit even for the same model due to manufacturing tolerances.

The ASUS PG279QZ produces a very small amount of color bleed when it displays large vertical bands of uniform colors. It is unlikely that you will notice this during normal usage. This very similar to sister monitor ASUS ROG PG279Q.

Picture Quality

The ASUS PG279QZ is good at handling reflections. The light matte coating reduces the intensity of direct reflections and diffuses them across the screen. So unless you are in a very bright room you should not have any issues.

Just like the sister monitor PG279Q, the response time of the PG279QZ is excellent. Only a very small blur trails the fast moving objects, and this is great for fast-paced video games. The overdrive setting that produces the fastest response time with minimal overshooting is the Normal. The Extreme option is faster, but it introduces a lot of overshoot.

The ASUS PG279QZ does not use flicker to dim the backlight. It does have an option to introduce flicker to make the image crisper. As this monitor supports G-Sync this Black Frame Insertion feature is called ULMB. Note here that the ULMB option only works with NVIDIA powered video cards. Also sometimes it is hard to notice the option on the OSD as it is grayed out on a black background which makes it hard to spot.

The monitor has a high native refresh rate of 144Hz, which can be overclocked up to 165Hz. It supports NVIDIA's G-Sync implementation of the variable refresh rate technology and can adjust the screen's refresh rate to match the frame rate of a compatible graphics card. This is great for playing graphically-intensive games with significant framerate drops without tearing or stuttering. The PG279QZ, just like its sister monitor the PG279Q, is among the best 144 Hz monitors and best 1440p 144hz monitors we've tested so far.

BFI frequency tested: 120 Hz

Excellent low input lag for the ASUS PG279QZ at the native resolution. The input lag remains low even when G-Sync is enabled and this is great news for gamers. When ULMB (BFI) is enabled the input lag is slightly higher but it remains at acceptable levels for most. Note that the input lag @60Hz is slightly higher than average, but it should not be noticeable to most. This monitor cannot properly display the non-native resolutions but this should not be a problem as most of the times the graphics card does the upscaling. Note that HDMI only supports a maximum resolution of 2560x1440p@60Hz.

Native Resolution 2560 x 1440
Aspect Ratio 16:9
Megapixels 3.7 MP

Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The ASUS PG279QZ is great for gaming due to the G-Sync variable refresh rate support. See our recommendations for the best gaming monitors, the best G-Sync monitors, and the best 1440p gaming monitors we've tested so far. 


The ASUS ROG PG279Q is very similar to the ASUS PG279QZ. The two monitors are nearly identical in design and have a very similar overall performance, except for brightness. The older PG279Q is brighter than the newer PG279QZ.

LG 27GL850-B

The LG 27GL850-B is slightly better than the ASUS ROG Swift PG279QZ for most uses. For gaming, the PG279QZ has better ergonomics, and an optional black frame insertion feature, but if these aren't very important to you, the 27GL850 has better motion handling overall, with a better response time, and it supports HDR.


The ASUS TUF VG27AQ is better than the ASUS ROG Swift PG279QZ. The TUF VG27AQ has better ergonomics, HDR support, and better black uniformity, but the ROG Swift has native support for G-SYNC, a slightly faster response time, and better reflection handling. Its out-of-box color accuracy is also better than the TUF VG27AQ.

Acer Predator XB271HU

The ASUS PG279QZ is somewhat better than the Acer Predator XB271HU. The ASUS PG279QZ has marginally better reflection handling, and it ships with a slightly better pre-calibration which is important for office users that usually don't calibrate their monitors.

Gigabyte Aorus AD27QD

Unless you want to get the most out of your NVIDIA graphics card, the Aorus AD27QD is slightly better than the ASUS PG279QZ. The Aorus supports HDR and has a few extra gaming features designed to give you a slight edge in competitive games, and it supports FreeSync. Although the Aorus also works with NVIDIA's new FreeSync drivers, if you want a true G-SYNC experience, the ASUS is very similar overall.

Razer Raptor 27

The ASUS ROG Swift PG279QZ and the Razer Raptor 27 are very similar for most uses, but the PG279QZ is better for gaming. The ASUS has much better ergonomics, so it's easier to adjust the screen to your ideal viewing position. The ASUS also has a much faster response time, resulting in clearer motion with less blur. The Razer Raptor has an incredible design, and unlike the ASUS it supports HDR, delivering a decent HDR gaming experience.


The ASUS PG279QZ and ASUS VG279Q are very similar overall, each with their strengths and weaknesses. The PG279QZ supports G-SYNC and has a higher native resolution. The VG279Q supports FreeSync, which is more universally supported, and the stand has better ergonomics.


The ASUS PG279QZ is better than the AOC AGON AG271QX for most people. The ASUS is an IPS monitor with much better viewing angles whereas the AOC has a TN panel with almost instantaneous response time and better black uniformity. The ASUS PG279QZ has better ergonomics and a BFI option to make the image crisper.

Samsung CHG70

The two monitors are of a different type, each with its advantages and disadvantages. The ASUS ROG Swift PG279QZ has an IPS and the image remains accurate when viewed from the side so it's more suitable if you often work with a colleague on the same monitor. The ASUS also has a faster response time and fast-moving content is crisper. The Samsung CHG70, on the other hand, has a higher contrast ratio, supports HDR, and has a local dimming feature to enhance dark room performance, so it's more suitable for dark room viewing.

Dell S2417DG

The ASUS PG279QZ is better than the Dell S2417DG. The two monitors have different panel types, but very similar motion handling and equally low input lag. The ASUS, apart from being larger, has an IPS panel with better picture quality and wider viewing angles that make it easier to share your work with a colleague.

LG 27UK650-W

Overall, the ASUS ROG Swift PG279QZ and the LG 27UK650-W are very similar, but the PG279QZ is a much better gaming monitor. The PG279QZ has a faster refresh rate, resulting in much clearer motion, and it has an optional black frame insertion feature to further clear up any blur. The LG 27UK650-W, on the other hand, has a higher native resolution and is slightly better for multitasking.

LG 27UD68

The ASUS PG279QZ is better than the LG 27UD68P-B. The ASUS PG279QZ has better ergonomics, lower input lag, higher refresh rate, and a faster response time that will please gamers. On the other hand, the LG 27UD68P-B has higher resolution that can fit more detail on the screen.
