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
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.
- 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.
- No HDMI 2.1 bandwidth.
- OLED Anti-Flicker setting adds 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 fights glare in most well-lit rooms, but reflections look distracting. 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.
- Wide viewing angles.
- Excellent ergonomics.
Disappointing reflection handling.
- Worse text clarity than other 27-inch, 1440p monitors.
- Risk of burn-in.
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.

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. A newer monitor, the ASUS ROG Strix OLED XG27AQWMG, has a higher 280Hz refresh rate and uses a newer Tandem OLED panel.
| Model | Size | Resolution | Refresh Rate | Notes |
|---|---|---|---|---|
| XG27AQDMG | 27" | 1440p | 240Hz | - |
| XG27AQDMGZ | 27" | 1440p | 240Hz | Best Buy exclusive |

Popular Monitor Comparisons
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, competing 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, but it has distracting reflections instead. At least 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 XG27AQWMG is an updated version of the ASUS ROG Strix OLED XG27AQDMG. The XG27AQWMG has a higher 280Hz refresh rate and comes with a newer Tandem OLED panel that gets brighter. The XG27AQWMG also has HDMI 2.1 bandwidth, which the XG27AQDMG lacks. Even though they both have glossy coatings, images look clearer on the TrueBlack Glossy coating of the XG27AQWMG.
The Gigabyte MO27Q28G is slightly better than the ASUS ROG Strix OLED XG27AQDMG. The newer fourth-generation panel on the Gigabyte delivers higher HDR peak brightness, with brighter specular highlight details and more vibrant bright scenes. The Gigabyte also has a slightly faster refresh rate, but it doesn't make a significant difference.
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 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.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
