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This is a newer version of the ASUS ROG PG279Q.

Pros
  • Excellent gaming features
  • Excellent motion handling
  • Image remains accurate when viewed at an angle
Cons
  • Blacks look gray in a dark room

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.

When it matters: When using a small desk, for those who require a monitor with a small footprint.
:
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.

8.2 Ergonomics
What it is: How much the position of the screen can be adjusted to match the viewing preference of the user.
When it matters: All usages, but especially office and gaming use.

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.

Back
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.

Borders
Borders
What it is: The distance from the left edge of the display to the start of the image.
When it matters: When using multiple monitors side-by-side.
:
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
Thickness (with stand)
What it is: How far the front of the screen protrudes when placed as far back as possible against a wall.
When it matters: When the monitor is placed back against a wall.
:

When it matters: When mounting a monitor with the stand removed.
:
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.

8.0 Build Quality
What it is: How well built and sturdy the monitor is, and how good the materials used to build it are.
When it matters: All usages.
Score components: Subjectively assigned

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.

Decent picture quality for the ASUS ROG Swift PG279QZ. Just like most IPS monitors, the contrast ratio is low and the monitor cannot display deep blacks in a dark room. It has a decent SDR peak brightness and is more suitable for a room that is not too bright. It has the typical good wide viewing angles of IPS panels, excellent gray uniformity, and a good out of the box color accuracy. Unfortunately, the monitor does not support HDR.

6.3 Contrast
What it is: Brightness difference between white and black. This is the main component of picture quality.
When it matters: Always, but especially when watching dark scenes.

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.

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.

7.5 Reflections
What it is: How much light is reflected by the TV.
When it matters: Bright rooms.
Score components: Subjectively assigned

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.

9.3

Motion

Score components:

The motion on this ASUS PG279QZ is excellent. The pixel response time is very fast and leaves only a very small motion blur behind fast moving objects. There is no flicker as the monitor does not use PWM dimming and this great for those that are bothered by flicker. It has an optional BFI feature, which NVIDIA calls ULMB, that can help make the image even crisper. Finally, it supports the G-Sync variable refresh rate for a very wide range of refresh rates. 

9.6 Motion Blur
What it is: The performance of the pixel response time. Poor response time causes trails to follow moving objects. Response time is one of a few sources of motion blur.
When it matters: When there's fast movement on screen, such as during video games and sports.
Score components:
80% Response Time

:
Normal

OD Off
OD Normal
OD Extreme

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.

9.4 Image Flicker
What it is: Luminosity pattern when displaying images
When it matters: Nearly all the time during PC monitor use, but especially during fast movement such as video games
Flicker-free : Yes
PWM Dimming Frequency

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.

9.2 Refresh Rate
What it is: How frequently the monitor can refresh and show new frames, and whether it can vary its refresh rate in real time using technologies like G-sync and FreeSync.
When it matters: Mostly for gaming, but does provide a little better motion during normal usage.

VRR Maximum With OC
What it is: The maximum frequency covered by the Variable Refresh Rate feature when the monitor's overclocking feature is used.
When it matters: When both the overclocking and VRR features are used.
Good value: Matching the overclocked refresh rate.
Noticeable difference: 10 hz
:
165 Hz
VRR Supported Connectors : DisplayPort

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.

8.4 Resolution and Size
What it is: The number of pixels the monitor can display, and the surface area of its screen.
