The ASUS ROG Swift 360Hz PG259QN is an excellent gaming monitor with exceptional motion handling. It has an outstanding response time, a Black Frame Insertion feature, and a 360Hz refresh rate, resulting in clear and smooth motion in fast-moving scenes. It has G-SYNC support and FreeSync compatibility to deliver a nearly tear-free gaming experience. It has good ergonomics and wide viewing angles, making it a great option for co-op gaming and sharing content. Unfortunately, while it gets bright enough to fight glare easily, it isn't enough to deliver a satisfying HDR experience. Also, the screen size might be too small for some, and its IPS panel's low contrast ratio makes it less ideal for gaming in the dark.

Our Verdict

8.0 Mixed Usage

The ASUS PG259QN is a great monitor overall. Although it's primarily designed for gaming, it's suitable for a wide range of uses. It has good ergonomics, wide viewing angles, and overcomes glare easily, making it ideal for work and media consumption. It's excellent for gaming due to its exceptional motion handling, low input lag, and VRR support. Sadly, it can't deliver a good HDR experience, as it lacks local dimming, a wide color gamut, and doesn't get bright enough to make highlights stand out.

Pros
  • Wide viewing angles.
  • Exceptional out-of-the-box accuracy.
  • Good ergonomics.
  • Great reflection handling.
Cons
  • Mediocre contrast ratio.
  • Screen might be too small for some.
7.9 Office

The ASUS PG259QN is good for office use. You can easily adjust the screen to your optimal viewing position thanks to its good ergonomics, and its IPS panel has wide viewing angles, making it ideal for sharing your work with coworkers. The screen might be too small for some, especially for multitasking, and the pixel density is a bit low, so text doesn't look as sharp.

Pros
  • Wide viewing angles.
  • Good ergonomics.
  • Great reflection handling.
Cons
  • Screen might be too small for some.
8.6 Gaming

The ASUS ROG Swift 360Hz PG259QN is excellent for gaming. It has a remarkably low input lag, outstanding response time, and a 360Hz refresh rate, resulting in an incredibly smooth and responsive experience. It has native G-SYNC support and FreeSync compatibility to reduce screen tearing. It isn't well-suited for gaming in the dark, though, as its IPS panel has a low contrast ratio that makes blacks look grayish.

Pros
  • 360Hz high refresh rate.
  • Superb response time.
  • Good ergonomics.
  • VRR support.
Cons
  • Mediocre contrast ratio.
  • Screen might be too small for some.
7.9 Multimedia

The ASUS PG259QN is good for media consumption. It has wide viewing angles and good ergonomics, so you can easily share your screen with others. It provides good visibility in bright environments because it handles reflections well and gets bright enough to fight glare, but it has a low contrast ratio that makes it less ideal for dark rooms. Also, some may find the screen too small.

Pros
  • Wide viewing angles.
  • Good ergonomics.
  • Great reflection handling.
Cons
  • Mediocre contrast ratio.
  • Screen might be too small for some.
7.9 Media Creation

The ASUS PG259QN is good for media creation. It has near-full coverage of the sRGB color space, superb gradient handling, and its out-of-the-box accuracy is exceptional, so you might not need to calibrate it to get accurate color reproduction. However, the resolution and screen size may be disappointing for some, and its low contrast ratio makes blacks look grayish.

Pros
  • Wide viewing angles.
  • Exceptional out-of-the-box accuracy.
  • Good ergonomics.
  • Great reflection handling.
Cons
  • Mediocre contrast ratio.
  • Screen might be too small for some.
7.3 HDR Gaming

The ASUS PG259QN is decent for gaming in HDR. It delivers an incredibly smooth and responsive gaming experience due to its exceptional motion handling and low input lag. However, it can't display a wide color gamut, lacks local dimming, and doesn't get bright enough to make highlights pop in HDR content.

Pros
  • 360Hz high refresh rate.
  • Superb response time.
  • Good ergonomics.
  • VRR support.
Cons
  • Mediocre contrast ratio.
  • No local dimming.
  • Can't display wide color gamut.
  • Screen might be too small for some.

The ASUS ROG Swift 360Hz PG259QN's design is very similar to the ASUS ROG Strix XG279Q, but the stand's feet now sit flat on the table. It has thin borders on three sides and a thicker bottom bezel. The back has an etched design and a Republic of Gamers (ROG) logo that lights up.

The back of the monitor has a fairly heavy gamer design. The ROG logo lights up, and you can control it through the on-screen menu or the Aura Sync software. There's a cutout at the bottom of the stand that allows cables to pass through for cable management. It can be VESA-mounted, but there's no quick-release feature to remove the stand.

Build Quality

The ASUS ROG Swift 360Hz PG259QN's build quality is great. The display is made of plastic, but it feels sturdy, and there are no loose parts. The stand has a solid metal base and supports the monitor well. All the hinges feel well-made, and it feels stable when rotating the screen. It doesn't have the most premium materials, but you shouldn't have any issues with it.

The ASUS PG259QN's HDR peak brightness is okay. It's again very consistent when displaying different scenes, but it isn't enough to make highlights stand out in HDR content.

We measured the HDR peak brightness in the 'HDR' Picture Mode. The screen's brightness isn't adjustable in this picture mode.

Before calibration, the ASUS PG259QN has exceptional accuracy; however, this can vary between units. White balance is nearly perfect, and the minor color inaccuracies aren't noticeable without the aid of a colorimeter. Gamma follows the sRGB curve relatively well, but both dark and bright scenes are slightly over-brightened. The color temperature is just slightly warmer than our 6500K. There's a dedicated 'sRGB' Picture Mode, and its accuracy is also exceptional, but not quite as good as the 'Racing' Picture Mode.

After calibration, accuracy is only slightly better since it was already exceptional out-of-the-box. White balance is closer to our 6500K target. Gamma is a little better, but dark scenes are still slightly too bright and bright scenes are too dark.

Unfortunately, although the ASUS PG259QN supports HDR, it can't display a wide color gamut. Its DCI P3 coverage is only decent, and it has poor coverage of the wider Rec. 2020 color space.

Due to the way we measure the DCI P3 coverage, our measurement is likely lower than most other reviewers. We measure it by sending a Rec. 2020 signal, but unlike most reviewers, we limit the colors to the DCI P3 primaries. This results in a lower but arguably more accurate measurement.

The ASUS ROG Swift 360Hz PG259QN has outstanding response time at its maximum refresh rate, resulting in clear images in fast-moving scenes. The recommended overdrive setting is 'Normal', as it provides the best performance without adding an overwhelming amount of overshoot like the 'Extreme' option. The 'Off' option has virtually no overshoot, but it's slower.

The ASUS PG259QN has an optional Black Frame Insertion feature to improve motion clarity. However, unlike other ASUS monitors, it's called Ultra Low Motion Blur (ULMB) and is advertised as NVIDIA's implementation of this technology. It only works at fixed refresh rates, 144Hz or 240Hz. It can't be used simultaneously with VRR and enabling it disables the overdrive settings menu. Also, it causes slight image duplication due to strobe crosstalk.
