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

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.

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.
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.
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.
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.
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.
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.
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.
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 has a gamer-oriented aesthetic that also wouldn't look out of place at an office. It features some RGB lighting on the back of the monitor.
The ergonomics are excellent. It has amazing height adjustment, so it's easy to place in your preferred position for a long gaming session. It also has an excellent swivel range, so it's easy to share your screen with someone else. Additionally, you can route your cables through the stand for cable management.
The flat stand holds the screen well, and you can place objects on top of it. There's also a groove in the stand to hold smartphones. The monitor has minimal wobble when bumped and recovers quickly.
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.
Settings
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:
Percent Window | Peak | Sustained |
---|---|---|
2% Window | 267 cd/mĀ² | 265 cd/mĀ² |
10% Window | 267 cd/mĀ² | 266 cd/mĀ² |
25% Window | 269 cd/mĀ² | 268 cd/mĀ² |
50% Window | 269 cd/mĀ² | 268 cd/mĀ² |
100% Window | 271 cd/mĀ² | 270 cd/mĀ² |
Settings
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:
Picture Mode | 2% Window Sustained | 10% Window Sustained |
---|---|---|
Gaming - Default | 749 cd/mĀ² | 741 cd/mĀ² |
Gaming - Max Brightness | 1,125 cd/mĀ² | 747 cd/mĀ² |
Cinema - Default | 749 cd/mĀ² | 740 cd/mĀ² |
Cinema - Max Brightness | 1,120 cd/mĀ² | 744 cd/mĀ² |
Console - Default | 747 cd/mĀ² | 740 cd/mĀ² |
Console - Max Brightness | 1,115 cd/mĀ² | 747 cd/mĀ² |
The horizontal viewing angle is fantastic. Although it technically isn't perfect, you visually won't see any inconsistencies when viewing from the sides or if you sit close to the screen.
Like the horizontal viewing angle, the vertical angle is fantastic, and you won't notice any inconsistencies when standing up and looking down at the monitor.
The accuracy before calibration is very good. It clamps colors to the sRGB color space well, and though it slightly oversaturates most colors it has good color accuracy. However, the color temperature is a bit warm, and the white balance is just decent. However, the gamma is off, as all parts of scenes are too dark.
Locked-Out Settings
If you want to access these settings which are locked out in the 'sRGB Cal Mode' you need to use another mode with worse color accuracy, like User.
The SDR color gamut is remarkable. It displays all colors in the common sRGB color space and a wide range of colors in the Adobe RGB color space. That said, green and red are quite inaccurate in Adobe RGB.
The HDR color gamut is fantastic. It displays nearly all colors in the common DCI-P3 color space and a wide range in the Rec. 2020 color space. However, not all colors are accurate, and white is particularly inaccurate in DCI-P3.
The monitor has great HDR color volume. Colors look vivid, and the monitor displays dark and bright colors well.
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:
Pixel Edge | ClearType On | ClearType Off |
---|---|---|
On | Windows 10 | Windows 10 |
On | Windows 11 | Windows 11 |
Off | Windows 10 | Windows 10 |
Off | Windows 11 | Windows 11 |
The reflection handling is superb. It does an amazing job of reducing glare, even from bright light sources. Though the monitor has a glossy display it diffuses light slightly more than most glossy screens, so objects reflected in the monitor have more of a halo around them than a typical glossy screen.
You can reach the monitor's max refresh rate over DisplayPort, but your graphics card needs to support Display Stream Compression (DSC) to reach the max refresh rate with 10-bit signals over DisplayPort. It also has a DSC Support setting to disable DSC if you prefer not to use it altogether. Because this monitor only has HDMI 2.0 bandwidth, the maximum refresh rate with HDMI is significantly slower.
NVIDIA VRR Min VRR Max DisplayPort <20Hz 240Hz HDMI <20Hz 144Hz AMD VRR Min VRR Max DisplayPort <20Hz 240Hz HDMI <20Hz 144Hz
On top of supporting FreeSync and G-SYNC compatibility, this monitor also supports HDMI Forum VRR.
The ASUS ROG Strix OLED XG27AQDMG has outstanding motion handling across its entire refresh rate range with VRR enabled. CAD remains low throughout, and there's minimal blur with fast-moving objects.
The refresh rate compliance is outstanding. With a near-instantaneous response time, it makes full-color transitions before drawing the next frame.
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:
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 Setting | Minimum Refresh Rate | Maximum Refresh Rate |
---|---|---|
Off | 40Hz | 240Hz |
Medium | 160Hz | 240Hz |
Strong | 200Hz | 240Hz |
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:
Flicker Levels | Medium | Strong |
---|---|---|
Dark Gray Flicker | 2.4 RGB | 1.0 RGB |
Middle Gray Flicker | 1.4 RGB | 0.4 RGB |
Light Gray Flicker | 0.7 RGB | 0.2 RGB |
Flicker Graph | Medium Graph | Strong Graph |
Flicker Video | Medium Video | Strong Video |
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 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:
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.
