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.

Update 02/22/2021: Some users have asked whether the Variable Backlight feature is a local dimming feature. It is not. We verified it using the test on the Lagom website. It seems to act more like a dynamic contrast feature, because the 253 white pattern is visible when it's off, but not when it's on, which means that it's affecting the contrast.

The ASUS ROG Swift PG259QN doesn't have a local dimming feature. The video above is provided for reference only.

The ASUS PG259QN has excellent accuracy before calibration. The sRGB mode limits colors to the sRGB color space, so they aren't oversaturated. The white balance and gamma are both also good. However, the color temperature is on the warm side, resulting in a reddish tint. Unfortunately, the sRGB mode limits some picture settings, including the Brightness, so if you want those enabled, use 'Racing Mode' instead, which performs nearly exactly like the sRGB mode anyways, as you can see here.

The ASUS ROG Swift PG259QN has an excellent 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 the response time is slower. If you want a 360Hz monitor with less overshoot, then check out the Dell Alienware AW2521H or the BenQ ZOWIE XL2566K, which also offers a customizable overdrive experience.

The ASUS ROG PG259QN's response time at 60Hz is very good, although noticeably blurrier than at its max refresh rate. The best overdrive setting is also 'Normal' because the 'Extreme' option adds more overshoot. If you want a similar 360Hz monitor with an even better response time at 60Hz, check out the Acer Predator X25 bmiiprzx.

The ASUS ROG Swift PG259QN has an optional backlight strobing feature to improve motion clarity. 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. There are different settings available with it to control the brightness of the backlight, and you can see the differences between them below.

The ASUS ROG PG259QN has a decent resolution and size. The screen might be a bit too small for productivity, and the pixel density is also low, so text and images don't look as sharp. That said, the 1080p resolution makes it easier for the graphics card to reach higher frame rates. If the resolution is important to you, the ASUS ROG Swift 360Hz PG27AQN is a 360Hz monitor with a 1440p resolution.

The ASUS PG259QN works as expected with the PS5. It can only display 1080p signals, and because it has native G-SYNC support, the PS5's VRR feature also works on it.

macOS Compatibility

The ASUS PG259QN works fine with macOS devices like a MacBook Pro. The refresh rate is limited to 240Hz, and there aren't any issues with VRR. Like most displays that use a USB-C to DisplayPort adapter, windows return to their original position when the laptop goes to sleep, but not when you close the lid.

The ASUS PG259QN has many additional features, including:

  • LED Bias Lighting: Controllable RGB lighting on the back of the monitor. A few lighting options are accessible through the on-screen menu, but you need the Aura-Sync software for full customization options.
  • Crosshair: Adds a virtual crosshair.
  • Timer: Adds a timer on the screen.
  • Frame Rate Counter: Adds an overlay display current frame rate.
  • Stopwatch: Adds a stopwatch on the screen.
  • Dark Boost: Helps make objects more visible in dark scenes.
  • Display Alignment: Helps with alignment in multi-monitor setups.

Unfortunately, unlike most of the other 360Hz G-SYNC monitors available now, like the MSI Oculux NXG253R, this monitor doesn't support NVIDIA's Reflex Latency Analyzer.
