The ASUS ROG Strix OLED XG27AQDMG is a 27-inch, 1440p gaming monitor with a 240Hz refresh rate. It has a variant sold at Best Buy called the XG27AQDMGZ. It uses Micro Lens Array+ (MLA+) technology that allows it to get bright, similar to other monitors in the Republic of Gamers (ROG) lineup, like the ASUS ROG Swift OLED PG27AQDP. It competes with other 27-inch OLED monitors, like the LG 27GS95QE-B. The XG27AQDMG includes a VRR flicker reduction feature, additional gaming features like Dynamic Shadow Boost, and an optional black frame insertion feature.

Our Verdict

9.0 PC Gaming

The ASUS ROG Strix OLED XG27AQDMG is fantastic for PC gaming. It has a fast 240Hz refresh rate and low input lag for a responsive feel. It delivers outstanding picture quality with deep, inky blacks, no blooming, and vivid colors. It supports all common VRR formats, and while it has noticeable VRR flicker with changing frame rates, this flicker is minimal if you're using its VRR flicker reduction feature. However, this can introduce some stuttering.

Pros
  • Deep and inky blacks.
  • 240Hz refresh rate and VRR support.
  • Near-instantaneous response time.
  • OLED Anti-Flicker setting eliminates most VRR flicker.
  • Low input lag.
  • Displays bright and vivid colors.
Cons
  • No HDMI 2.1 bandwidth.
  • OLED Anti-Flicker setting adds stuttering.
8.3 Console Gaming

The ASUS ROG Strix OLED XG27AQDMG is great for console gaming, and it works well with the PS5. However, with the Xbox Series X|S, you have to choose between having a 60Hz refresh rate with HDR and a downscaled image or a 120Hz refresh rate without HDR. With either console it provides high-end gaming performance as it has a near-instantaneous response time, so fast-moving objects are sharp, and it has low input lag for a responsive feel. It also has exceptional picture quality with perfect blacks and no blooming around bright objects.

Pros
  • Deep and inky blacks.
  • Near-instantaneous response time.
  • OLED Anti-Flicker setting eliminates most VRR flicker.
  • Low input lag.
  • Displays bright and vivid colors.
Cons
  • No HDMI 2.1 bandwidth.
  • Can't take full advantage of gaming consoles.
7.7 Office

The ASUS ROG Strix OLED XG27AQDMG is good for office use in certain circumstances. It has good brightness and fantastic reflection handling, so it's visible in most lighting conditions, though it doesn't get bright enough to fight very intense glare. It also has great ergonomics and wide viewing angles that help you share the screen with someone else. However, it has only adequate text clarity, and text is less sharp than many other 1440p displays. Finally, OLEDs like this one are prone to burn-in with constant exposure to the same static elements over time.

Pros
  • Incredible reflection handling.
  • Wide viewing angles.
  • Excellent ergonomics.
Cons
  • Worse text clarity than other 27-inch, 1440p monitors.
  • Risk of burn-in.
8.6 Editing

The ASUS ROG Strix OLED XG27AQDMG is excellent for media creation but has some limitations. It has an accurate sRGB mode, though you need to calibrate it for the most accurate image. Additionally, its vivid colors and wide HDR gamut range allow you to edit videos in HDR effectively. However, text is less sharp than other 27-inch 1440p monitors. Also, OLEDs like this one are prone to burn-in with constant exposure to the same static elements over time.

Pros
  • Incredible reflection handling.
  • Wide viewing angles.
  • Good accuracy before calibration.
  • Excellent ergonomics.
Cons
  • Worse text clarity than other 27-inch, 1440p monitors.
  • Risk of burn-in.
7.5 Brightness

The ASUS ROG Strix OLED XG27AQDMG has good brightness. It has very good SDR brightness and is bright enough to overcome glare in most situations, though it isn't bright enough to fight very intense glare. It gets quite bright in HDR, and smaller highlights really pop, but the screen gets dimmer with larger highlights.

Pros
  • Smaller highlights pop against the rest of the image.
Cons
  • Not bright enough to fight very intense glare.
9.9 Response Time

The ASUS ROG Strix OLED XG27AQDMG has a near-instantaneous response time, resulting in exceptionally sharp motion.

Pros
  • Near-instantaneous response time.
  • Outstanding refresh rate compliance.
Cons
9.0 HDR Picture

The ASUS ROG Strix OLED XG27AQDMG is outstanding for HDR. It displays deep and inky blacks without any blooming around bright objects thanks to its near-infinite contrast ratio and perfect black uniformity. It also displays a wide range of colors and makes them look vivid.

Pros
  • Deep and inky blacks.
  • Displays bright and vivid colors.
Cons
9.9 SDR Picture

The ASUS ROG Strix OLED XG27AQDMG has outstanding SDR picture quality, displaying deep and inky blacks and a wide range of colors.

Pros
  • Deep and inky blacks.
  • No blooming around bright objects.
Cons
8.4 Color Accuracy

The ASUS ROG Strix OLED XG27AQDMG has great color accuracy. While it has an accurate sRGB mode, you still need to calibrate it for the best accuracy.

Pros
  • Good accuracy before calibration.
  • Excellent gray uniformity.
Cons
  • 9.0 PC Gaming
  • 8.3 Console Gaming
  • 7.7 Office

Differences Between Sizes And Variants

We tested the 27-inch ASUS ROG Strix OLED XG27AQDMG, which is the only size available. It's also sold at Best Buy as the XG27AQDMGZ, and because it's the same monitor, the review is also valid for it.

Compared To Other Monitors

The ASUS ROG Strix OLED XG27AQDMG is a 27-inch gaming monitor with a 1440p resolution and 240Hz refresh rate. It's a newer monitor than the ASUS ROG Swift OLED PG27AQDM, and it competes against OLED monitors with the same specs. However, it's different from the competition in a few ways because it has a glossy screen, so images appear clearer than on those with a matte coating. It also gets much brighter than most other WOLEDs thanks to its MLA+ layer, and small highlights really pop in HDR, so in many ways, its picture quality is more in line with higher-end QD-OLED displays. That said, it doesn't have the same vivid colors as a QD-OLED.

See our recommendations for the best 1440p monitors, the best 27-inch gaming monitors, and the best OLED monitors.

ASUS ROG Swift OLED PG27AQDM

The ASUS ROG Strix OLED XG27AQDMG is a newer generation of 27-inch OLED monitor than the ASUS ROG Swift OLED PG27AQDM. Some of the changes with the XG27AQDMG include a much brighter screen in SDR, a glossy finish, and the ability to display a wider range of colors in HDR, making it the better choice for most gamers. However, if you prefer a matte display and don't mind the reduced brightness, you won't be disappointed by the older PG27AQDM.

Gigabyte AORUS FO27Q3

The ASUS ROG Strix OLED XG27AQDMG and the Gigabyte AORUS FO27Q3 are both 27-inch OLED gaming monitors, but they have a few differences. They have different OLED panel types, with the Gigabyte being a QD-OLED with more vivid colors. The Gigabyte also has a higher refresh rate, which is ideal for competitive gaming. On the other hand, the ASUS gets brighter, so it's the better choice if you want something to use in a well-lit room.

LG 27GS95QE-B

The LG 27GS95QE-B and the ASUS ROG Strix OLED XG27AQDMG are very similar 27-inch OLED gaming monitors. The ASUS is a better option if you prefer the vividness of a glossy screen. The ASUS is also a better choice if you find VRR flicker distracting, as it has a setting to reduce this, though it causes some stutter. However, the LG is better if you prefer a more consistent display in different lighting conditions with its matte screen. It's also a better choice if you plan to use the Xbox Series X|S with your monitor, as it's more compatible with that console.

MSI MPG 271QRX QD-OLED

The MSI MPG 271QRX QD-OLED and the ASUS ROG Strix OLED XG27AQDMG are 27-inch OLED gaming monitors. The ASUS is a better option if you're gaming in a bright room, as deep blacks don't appear slightly purple when there's a lot of ambient light on the screen, and it gets much brighter. However, if you like to play competitive games, the MSI is a better choice, as it has lower input lag and a higher refresh rate.

Dell Alienware AW2725DF

The Dell Alienware AW2725DF and the ASUS ROG Strix OLED XG27AQDMG are 27-inch OLED gaming monitors. The ASUS is a better option if you're gaming in a bright room, as it gets much brighter, and deep blacks don't appear slightly purple when there's a lot of ambient light on the screen. However, the Dell is a better choice if you play a lot of competitive games, as it has a higher refresh rate and a more responsive feel. It also displays more vivid colors in HDR, and the text looks slightly sharper.

Samsung Odyssey OLED G6/G60SD S27DG60

The Samsung Odyssey OLED G6/G60SD S27DG60 and the ASUS ROG Strix OLED XG27AQDMG are both 27-inch OLED gaming monitors. If competitive gaming is important to you, then the Samsung is a better option, as it has a higher refresh rate and feels more responsive. It also has sharper text and displays a wider range of colors. However, if you're gaming in a bright room, the ASUS is a better choice, as it gets brighter, and it doesn't appear purple at all if there's a lot of ambient light shining on the screen.

ASUS ROG Swift OLED PG27AQDP

The ASUS ROG Swift OLED PG27AQDP and the ASUS ROG Strix OLED XG27AQDMG are both 27-inch, 1440p OLED gaming monitors. The main difference is that the PG27AQDP has a higher 480Hz refresh rate compared to 240Hz on the XG27AQDMG, which is useful for competitive gaming. The PG27AQDP also has HDMI 2.1 bandwidth to take full advantage of modern graphics cards and gaming consoles. While the text clarity is similar between them, the PG27AQDP has less fringing, but the XG27AQDMG has a clearer image because of its glossy coating.

Dell Alienware AW3225QF

The Dell Alienware AW3225QF and the ASUS ROG Strix OLED XG27AQDMG are OLED gaming monitors. The Dell is the better choice if you want an immersive experience, as its larger screen and more detailed images create a more immersive experience. However, the ASUS is a better option if you don't have a very powerful gaming PC, as your computer can run games at a higher frame rate on the monitor's native 1440p resolution than the Dell at its native 4k resolution. The ASUS is also a better choice if you're in a room with a fair bit of ambient light, as deep blacks don't appear slightly purple on the ASUS in that setting.

The ASUS ROG Strix OLED XG27AQDMG 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 good. It gets bright enough to fight glare in most well-lit rooms. However, with Uniform Brightness 'Off,' the screen's brightness varies depending on how much of your screen has very bright content, which could be distracting. Turning it 'On' ensures the screen's brightness doesn't vary, and you can see the results below:

The HDR brightness is decent. It gets bright enough to make smaller highlights pop, but it can't sustain this brightness with larger highlights, so they don't stand out as much. It follows the PQ EOTF curve fairly well until there's a very sharp roll-off at peak brightness, letting highlights get the brightest they can.

Peak Brightness

While this monitor doesn't have a dedicated peak brightness setting, the peak brightness of smaller highlights is significantly increased when you enable Brightness Adjustable, which is off by default, and set Brightness to '100'. Together, these settings significantly increase the maximum brightness of very small highlights, but not larger ones, as you can see below:

The text clarity is okay, though it's not as good as some other 27-inch 1440p monitors because of its RWBG subpixel layout. This results in some color fringing around text if ClearType is enabled.

Though Pixel Edge is supposed to reduce fringing, it's still present when ClearType is enabled, and text looks less bold. You can see how enabling ClearType and Pixel Edge in both Windows 10 and Windows 11 affects text clarity below:

The CAD at the maximum refresh rate is outstanding. It displays fast-moving objects as intended, and motion is extremely sharp.

This monitor has an optional black frame insertion feature to reduce persistence blur, but it only works with fixed 120Hz signals. When it's on, you can adjust the brightness between 15.28 cd/mĀ² and 131.5 cd/mĀ². The following settings are locked out when it's enabled:

  • Blue Light Filter
  • Variable Refresh Rate
  • HDR

The ASUS ROG Strix OLED XG27AQDMG has quite distracting VRR flicker with changing frame rates if OLED Anti-Flicker is off. It can be particularly distracting if the frame rate changes a lot, especially in darker parts of scenes. That said, this doesn't happen if your PC can maintain consistent frame rates.

OLED Anti-Flicker Setting

OLED Anti-Flicker minimizes VRR flicker by reducing the refresh rate range VRR operates at, as you can see below:

OLED Anti-Flicker SettingMinimum Refresh RateMaximum Refresh Rate
Off40Hz240Hz
Medium160Hz240Hz
Strong200Hz240Hz

While this introduces some stuttering, it significantly reduces VRR flicker. While flicker is reduced significantly with 'Medium', and even more with 'Strong', random VRR flicker is still present. You can see this below, though random VRR flicker is slightly worse than the video indicates:

The backlight isn't technically flicker-free because it has a slight dip in brightness that corresponds to the 240Hz refresh rate.

The ASUS ROG Strix OLED XG27AQDMG has low input lag, especially at its max refresh rate. While its input lag is a bit higher than some other monitors with 120Hz and 60Hz sources, it's still low enough for a responsive feel.

The Xbox doesn't support HDR with 1440p or 1080p signals, so this isn't a limitation of the monitor.

The ASUS ROG Strix OLED XG27AQDMG doesn't have any compatibility issues with macOS. If you're using a MacBook windows move to the monitor's screen when you close the laptop's lid, and they return to their original position when you reopen it again over any type of connection. VRR works well, and colors in HDR look good.

The ASUS ROG Strix OLED XG27AQDMG has several additional features, including:

  • Dynamic Shadow Boost: Adjusts gamma so that you can see opponents better in dark scenes.
  • GamePlus: Includes different gaming features like an FPS counter, crosshairs, sniper mode, stopwatch, and timer.
  • Lighting Effect: Controls the RGB lighting on the back of the monitor and on the stand.
  • Low Blue Light Filter: Reduces blue light to help with eye strain.

Like most OLED displays, there are also a few settings to help reduce the risk of burn-in, which you can find in the Screen Protection section of the OSD.

  • Auto Logo Brightness: Dims static logos that are on the screen, like if you're watching TV.
  • Pixel Cleaning: This feature calibrates any burn-in issues that may occur. It happens after you turn off the screen and takes about six minutes to finish. There's also a setting to remind you to turn off the monitor so it can perform the cycle.
  • Screen Move: Moves the image by a few pixels to one side to help reduce the risk of burn-in.
  • Screen Saver: Automatically dims the screen when there's inactivity.
