ASUS PG27AQN Review: 1440p 360Hz 1ms IPS G-SYNC HDR Gaming Monitor

The ASUS PG27AQN is a 27" 1440p 360Hz 1ms IPS gaming monitor with a dedicated G-SYNC module, DisplayHDR 600 and a wide 98% DCI-P3 color gamut.

Bottom Line

The ASUS PG27AQN is the best gaming monitor if you’re looking for a single display for competitive gaming and other use (office-related work, photo/video editing, AAA gaming, etc.).

The ASUS ROG Swift PG27AQN is the first 1440p monitor with a refresh rate of 360Hz, which makes it the ideal display for those who enjoy both competitive and graphically-oriented games!

Image Quality

For a lot of gamers, the 1440p resolution is perfect for 27″ sized screens. The image quality is almost as good as that of 4K UHD at this screen size, but since 1440p is significantly less demanding to drive, maintaining a higher frame rate is a lot easier.

Further, with a pixel density of 108.79 PPI (pixels per inch), you get plenty of screen real estate with sharp details and text – without having to use any scaling.

The ASUS PG27AQN uses an IPS panel with a wide 98% DCI-P3 color gamut, which is equivalent to around 135% sRGB gamut size, resulting in rich and vibrant colors.

There’s also an sRGB mode under the ‘Display Color Space’ option in the OSD (On-Screen Display) menu that clamps the gamut down to 100% sRGB in case you want more accurate colors for SDR content.

What’s more, the display is factory-calibrated at Delta E < 2, which in addition to the 178° wide viewing angles of IPS technology, results in accurate and consistent color output fit for professional color-critical work!

As expected from an IPS display, the static contrast ratio amount to 1,000:1 and there’s some IPS glow, so blacks won’t appear quite as deep as that of VA panels with ~3,000:1 contrast ratio, but VA monitors have other drawbacks and this 1440p 360Hz form factor is only available as an IPS variant anyway, at least for now.

Moving on, the ASUS PG27AQN monitor has a specified SDR peak brightness of 400-nits (though it can reach up to 500-nits), so it won’t have any issues mitigating glare in particularly well-lit rooms.

It also supports HDR (High Dynamic Range) and has VESA’s DisplayHDR 600 certification. However, since it only has 32 edge-lit dimming zones, you’re not getting the true HDR viewing experience.

Edge lit Dimming vs Full array Dimming

Its wide color gamut and 600-nit peak brightness in HDR mode can make some content a lot better than SDR, and local dimming can be helpful in scenes with dark and bright objects far apart.

On the other hand, in particularly demanding scenes, you might find that enabling HDR causes more distractions than improvements, so whether you should turn HDR and local dimming (Variable Backlight) on or off will vary from content to content.

Performance

The ASUS ROG Swift PG27AQN uses an Ultrafast IPS panel by AU Optronics paired with the new Dual-Layer Voltage Driver, which together make for a rapid pixel response time speed required to keep up with the 360Hz refresh rate.

There’s no noticeable trailing behind fast-moving objects at 360Hz, while the dedicated G-SYNC module with variable overdrive ensures no overshoot at lower refresh rates, as well as imperceptible ~1ms input lag and tear-free gameplay up to 360FPS.

G Sync Module

Of course, to actually benefit from 360Hz, you’ll need to be able to achieve such high frame rates, which requires a fast CPU. With an Intel 12th Gen or Ryzen 5000 series CPU and a decent GPU, this won’t be an issue with low/medium settings at 1440p in the popular eSports titles.

The monitor also supports Adaptive-Sync over DisplayPort if you wish to use a variable refresh rate with an AMD GPU.

There are four response time overdrive modes: Off, Normal, Esports and Extreme. Esports and Extreme both add noticeable inverse ghosting, so we recommend sticking with Normal for the best results. Below 100FPS, you might start noticing some inverse ghosting, in which case you should use the Off overdrive mode.

Sadly, the ASUS PG27AQN doesn’t support Motion Blur Reduction.

The backlight of the monitor is flicker-free and there’s an integrated low-blue light filter.

Features

ASUS PG27AQN OSD Menu

At the rear of the monitor, there’s the power button, three buttons for shortcuts and a directional joystick for quick and easy navigation through the OSD menu.

The ASUS PG27AQN supports NVIDIA Reflex Latency Analyzer, which allows you to measure input latency if you have a compatible mouse connected to the red-colored USB port on the monitor.

Other gaming features include Dark Boost (improves visibility in dark scenes by altering the gamma curvature), crosshair overlays, various picture presets, on-screen timers and a refresh rate tracker.

Besides the standard image settings (brightness, contrast, color temperature, etc.), you’ll also find some advanced tools, including five gamma presets, 6-axis saturation and Auto Input Detection.

There’s also an integrated light sensor that can automatically adjust the screen brightness according to ambient lighting.

Next, the monitor has an interesting feature called Esports Dual-Format. Under the Aspect Control option in the OSD menu, you’ll find 25″ Mode, which will make the ASUS PG27AQN display the image as a 25″ display with black bars around it.

Esports Dual Mode

In this mode, you can select either 2368×1332 resolution or 1920×1080, though the latter ends up being blurry.

Design & Connectivity

ASUS ROG Swift PG27AQN Review

The stand of the monitor is robust and versatile with up to 100mm height adjustment, 90° pivot, +/- 25° swivel, -5°/20° tilt and 100x100mm VESA mount compatibility, while the screen has a light matte anti-glare coating that eliminates reflections without making the image too grainy.

The G-SYNC module also has a cooling fan, but it’s pretty quiet. Of course, if you’re in a silent room and have a silent PC rig running, you will be able to hear it. With headphones, speakers, or any other background noise, it’s not an issue.

Connectivity options include DisplayPort 1.4 with DSC, three HDMI 2.0 ports (limited to 144Hz), a headphone jack and a dual-USB 3.0 hub.

Price & Similar Monitors

The ASUS PG27AQN price amounts to $1,050, which is understandable given its specifications and the fact that it’s the only such display available.

However, we feel that for a lot of gamers who want a single display for both competitive and graphically-oriented games, something like the Gigabyte M27Q-X with a 1440p 240Hz IPS panel for ~$400 will do just fine.

It doesn’t have quite as fast response time, as good overdrive implementation, as wide color gamut or as high brightness, but it offers excellent value for money.

Of course, if you already have a high-end PC rig and are actually getting over 360FPS in your games, then investing in the PG27AQN makes sense.

For those who prefer motion clarity over color gamut and resolution, fast gaming monitors with excellent MBR implementation, such as the ViewSonic XG2431 and the BenQ XL2566K, are also worth considering.

Conclusion

All in all, the ASUS ROG Swift PG27AQN is one of the best gaming monitors out there. It’s particularly great if you’re a serious competitive player who also wants an excellent display for other use. If only it had backlight strobing – it’d be perfect for fans of CRT-like motion clarity as well.
