The ASUS ROG Swift OLED PG27AQDP is a premium OLED gaming monitor. Featuring a 480Hz refresh rate with a 27-inch screen and 1440p resolution, it competes against monitors with the same specs, like the Acer Predator X27U F3, the Sony INZONE M10S, and the AOC AG276QKD. Like some high-end TVs, it uses Micro Lens Array+ (MLA+) technology that lets it get brighter than other OLED monitors. It has features you'd expect to find in a premium gaming monitor, like HDMI 2.1 bandwidth, and it has other perks to improve your gaming experience, like OLED Anti-Flicker and Extreme Low Motion Blur. It even has some OLED Care settings to reduce the risk of burn-in associated with OLEDs, and it has a custom heatsink.

Our Verdict

9.2 PC Gaming

The ASUS PG27AQDP is remarkable for PC gaming. With a high 480Hz refresh rate, it's a fantastic choice for most PC gamers, and it supports any VRR format to reduce screen tearing. Motion looks incredibly sharp thanks to its fast response time, and it has low input lag with most refresh rates, except for 60Hz signals, where it increases. On top of that, it delivers incredible picture quality with deep blacks and bright highlights. However, there are some downsides, as it has noticeable VRR flicker with changing frame rates. The monitor's software also has a lot of bugs, causing settings to change randomly or not work altogether.

Pros
  • Incredibly high 480Hz refresh rate.

  • Supports all common VRR formats.

  • Fast response time for sharp motion.

  • Low input lag with most signals.

  • Displays deep and inky blacks.

  • Small highlights pop in HDR.

Cons
  • Software has noticeable bugs.

  • Very high input lag with 60Hz signals.

  • Noticeable VRR flicker.

9.0 Console Gaming

The ASUS PG27AQDP is fantastic for console gaming. It has HDMI 2.1 bandwidth to take full advantage of the PS5 and Xbox Series X|S, including supporting downscaled 4k signals. Its near-instant response time results in incredibly sharp motion, and it has low input lag with 120Hz signals. However, the input lag is a lot higher with 60Hz signals, which is disappointing for playing reaction-based games. On the plus side, games look realistic thanks to its incredible picture quality with deep blacks and bright highlights. It even gets bright enough to fight glare in most well-lit rooms.

Pros
  • Fast response time for sharp motion.

  • Low input lag with most signals.

  • Displays deep and inky blacks.

  • Small highlights pop in HDR.

  • Supports any signal from PS5 and Xbox Series X|S.

Cons
  • Software has noticeable bugs.

  • Very high input lag with 60Hz signals.

7.7 Office

The ASUS PG27AQDP is good for office use. It gets bright enough to fight glare in most well-lit rooms and has fantastic reflection handling. Its wide viewing angles and versatile ergonomics are also useful for sharing your screen with someone next to you.

Pros
  • Bright enough to fight glare in most well-lit rooms.

  • Fantastic reflection handling.

  • Versatile ergonomics.

Cons
  • Software has noticeable bugs.

  • Text clarity issues.

  • Risk of burn-in.

8.6 Editing

The ASUS PG27AQDP is excellent for editing. The main benefit of using it for content creation is its incredible picture quality, as it displays deep blacks without any blooming, and highlights pop in HDR, too. It also gets bright enough to fight glare in most well-lit rooms. It displays a wide range of colors and has an accurate sRGB mode, but you need to calibrate it for the best accuracy. Unfortunately, it has the risk of permanent burn-in with constant exposure to static elements over time, like from your editing programs. The software also has bugs that change settings at times, which can be problematic if you need specific settings for your editing.

Pros
  • Displays deep and inky blacks.

  • Small highlights pop in HDR.

  • Bright enough to fight glare in most well-lit rooms.

  • Dedicated sRGB mode.

Cons
  • Software has noticeable bugs.

  • Risk of burn-in.

  • Larger highlights are somewhat muted.

  • Needs full calibration for best accuracy.

7.3 Brightness

Differences Between Sizes And Variants

We bought and tested the 27-inch ASUS PG27AQDP, which is the only size available. Although there are other 1440p OLEDs in the ROG gaming lineup, they're different monitors, and the results are only valid for this model.

ModelSizeResolutionRefresh Rate
ROG Swift OLED PG27AQDP27"1440p480Hz

Our unit's label indicates that it was manufactured in August 2024. We tested it with firmware MCM103.

Compared To Other Monitors

The ASUS ROG Swift OLED PG27AQDP is a 1440p OLED gaming monitor with a high 480Hz refresh rate. It's a great upgrade over other ROG Swift monitors, like the ASUS ROG Swift OLED PG27AQDM, if you want something with a high refresh rate. It also offers all the benefits of an OLED, like perfect contrast, and its MLA+ layer allows it to get bright. While it has fantastic hardware, its software has some drawbacks. It has bugs that can negatively impact your gaming experience, as settings randomly change or don't work at all, so it may be worth waiting until these get fixed with a firmware update before buying the monitor. That said, in terms of pure gaming performance, it's one of the best gaming monitors you can get.

Build Quality

The build quality is excellent. The housing holding the panel is metal, and the transparent plastic on the back covering the inputs doesn't flex easily. The stand is well-made and features a plastic pillar and metal feel that hold the screen well. Overall, there aren't any major issues, and there isn't any noticeable coil whine or fan noise, either.

The tripod stand takes up a lot of space, but there's space between the feet to place your keyboard and mouse. As the stand is tilted, the thickness from the display to the back of the stand depends on the height at which you set the screen. The thickness measurement is with the screen at the lowest height, and thickness at the max height is 8.3" (21.0 cm).

The ASUS ROG Swift OLED PG27AQDP doesn't have a backlight, so it doesn't require a local dimming feature. However, with a near-infinite contrast ratio, there isn't any blooming around bright objects, and it's the equivalent of a perfect local dimming feature. We still film these videos on the monitor so you can see how the screen performs and compare it with a monitor that has local dimming.

The SDR brightness is very good. It gets bright enough to fight glare in most well-lit rooms, but you may struggle to properly see the screen if you have it opposite a sunny window. Although turning Uniform Brightness off results in some changes in brightness between different content, it isn't distracting. Turning it on makes the brightness more consistent between different content, but it makes the screen dimmer, as you can see below:

  • Adjustable HDR: On
  • Brightness: 100
  • Uniform Brightness: Off
  • OLED Care: All settings off

The HDR brightness is okay. It gets bright enough to fight glare in most well-lit rooms, and it also makes small highlights pop against the rest of the image. However, it doesn't sustain the brightness with larger highlights. The 'Console HDR' mode is the brightest and most accurate as it follows the PQ EOTF well for the most part, but bright highlights are overbrightened. It has a sharp cut-off at the peak brightness, so highlights get the brightest they could.

The EOTF is the same in the 'True Black 400' picture mode, for which you can see the brightness results below, along with the Uniform Brightness setting on, which you can only enable if you also turn on Adjustable HDR.

The accuracy is great before calibration in the 'sRGB Cal Mode' Game Visual. It locks colors well to the sRGB color space, but it isn't perfect, as there are inaccuracies with the white balance and most colors. Even gamma is very off, as bright scenes are overbrightened. The 'User' mode has better gamma tracking, but colors are oversaturated.

Although it has less fringing than other 27-inch, 1440p OLEDs with an RWBG subpixel layout, like the ASUS ROG Strix OLED XG27AQDMG, it doesn't make text significantly better, and there's still some fringing. Without using ClearType, there's no fringing but letters are harder to read. These photos are in Windows 10, and you can also see them in Windows 11 with ClearType on and with ClearType off.

The reflection handling is fantastic. It reduces glare well, and reflections aren't distracting. Although the coating is similar to a matte screen like the Samsung Odyssey OLED G6/G60SD S27DG60, it's not as aggressive as a typical matte screen, but it doesn't have direct reflections like a glossy screen either, so it's a mix of the two coatings.

The ASUS PG27AQDP has a black frame insertion feature to reduce persistence blur. It only works with fixed 240Hz or 120Hz signals and reduces blur well. You can also adjust the brightness too, with the minimum brightness being 16 cd/m2. You can only enable ELMB with VRR disabled, and using this settings locks you out of the Aspect Control and Uniform Brightness settings.

This monitor has terrible VRR flicker with changing frame rates, which is most distracting in dark scenes. That said, it has an OLED Anti-Flicker setting that reduces the VRR flicker by limiting the refresh rate range, but it also introduces stutter and doesn't eliminate all flicker. You can see the results for the different settings below:

The backlight isn't technically flicker-free because it has a slight dip in brightness that corresponds to the 480Hz refresh rate.

The ASUS ROG Swift PG27AQDP has low input lag with most refresh rates for a responsive feel. However, it increases a lot more with fixed 60Hz signals, but this isn't an issue if you start gaming at a higher refresh rate and use VRR as the refresh rate drops.

We couldn't measure the input lag with Aspect Control because we couldn't enable it.

There aren't any compatibility issues, and the monitor downscales 4k signals, which results in a more detailed image than native 1440p.

This monitor works well with the Xbox Series X|S, and downscales 4k signals. This is useful as the Xbox only supports HDR with 4k signals.

The ASUS PG27AQDP works well with macOS. VRR works properly, but there's still VRR flicker with changing frame rates. The max refresh rate depends on the chip you're using, as it goes up to 240Hz with an M1 chip. If you're using a MacBook and close the lid, windows migrate to the screen, and opening the lid causes the windows to return to their original position.

The ASUS PG27AQDP has a ton of extra features to improve your gaming experience, including:

  • AI Assistant: This includes AI Crosshair, AI Shadow Boost, and AI Sniper features that make it easier to see opponents that your game's anti-cheat tool won't detect.
  • Aspect Control: You can change the display area to simulate a 24.5-inch image or a squared aspect ratio. You can also enable Pixel by pixel to stretch the image for a 3288x1850 resolution.
  • Blue Light Filter: Reduces blue light to help reduce eye strain.
  • GamePlus: Includes gaming modes like FPS Counter, Crosshair, Sniper, and Display Alignment.
  • Lighting Effect: Offers settings to control the monitor's RGB lighting.

It also includes a few settings to reduce the risk of burn-in associated with OLEDs. They're all under the OLED Care section:

  • Screen Saver: Dims the screen when there's no movement on the screen after a certain period.
  • Screen Move: Moves the image by a few pixels at a time so that pixels aren't always displaying the same thing.
  • Pixel Cleaning: This feature fixes any burn-in issues, and it runs when you turn the screen off. It takes about six minutes to complete, and there's a reminder that pops up when to start it.
  • Auto Logo Brightness: Dims static logos on the screen. There's also a Taskbar Detection setting to move the taskbar to the outer parts of the display area.

We tested this monitor with firmware MCM103 and experienced many bugs with it. The settings often change or become grayed out for no reason, even without us changing any settings. Some settings, like Aspect Control, didn't work at all. We also experienced issues with the monitor having to reset the image a few times when changing the refresh rate or turning VRR on/off from our PC.

We'll check for these issues if there's a new firmware update.
