The ASUS ROG Strix OLED XG27ACDNG is a premium 27-inch, 1440p gaming monitor with a QD-OLED panel. Featuring a 360Hz refresh rate, it competes against other monitors that have the same specs, like the Gigabyte AORUS FO27Q3, MSI MPG 271QRX QD-OLED, and the Dell Alienware AW2725DF, and it sits above the ASUS ROG Strix OLED XG27AQDMG in the ROG Strix gaming lineup. It has typical gaming features, like VRR support, DP 1.4 and HDMI 2.1 bandwidth, and Extreme Low Motion Blur (ELMB). It also includes a heatsink and OLED Care+ settings to reduce the risk of burn-in. On top of that, it has some productivity features, like a USB hub that includes a USB-C port with 90W of power delivery and a KVM switch.
Our Verdict
The ASUS XG27ACDNG is remarkable for PC gaming. Its 360Hz refresh rate is ideal for most gamers, and gaming feels responsive and smooth thanks to its low input lag and extremely sharp motion handling. Plus, it delivers outstanding picture quality, especially for gaming in dark rooms, as blacks are deep and inky, and small highlights pop against the rest of the image. However, there are some downsides, as the black levels rise in bright rooms, so they look purple. It also has distracting VRR flicker with changing frame rates, which you can mostly notice in dark scenes.

The ASUS XG27ACDNG is fantastic for console gaming. Although it has to downscale 4k signals, it doesn't have any compatibility issues with the PS5, PS5 Pro, and Xbox Series X|S. Gaming feels responsive thanks to its low input lag, and motion looks incredibly sharp. On top of that, its picture quality is outstanding, particularly in HDR, as it displays deep blacks next to bright highlights and a wide range of vivid colors. However, it performs best in a dark room, as using it in a bright room causes the black levels to rise, making them look purple.

The ASUS XG27ACDNG is decent for office use, but it has some limitations. It gets bright enough to fight glare in most well-lit offices and has decent reflection handling. It also comes with an ergonomic stand and has wide viewing angles, making it easy to share your screen with someone next to you. It also has a few useful productivity features, like a KVM switch and USB hub that makes it easier to connect different devices. However, OLEDs like this risk burn-in with constant exposure to the same static elements over time, like if you always have the taskbar open. Also, while its text clarity is decent, it has some fringing around letters, and text isn't as sharp as on a 27-inch, 1440p IPS display.

The ASUS XG27ACDNG is amazing for content creation. It displays accurate colors before calibration in its dedicated sRGB mode, but calibrating it still results in the best accuracy. It also delivers outstanding picture quality thanks to its deep blacks in dark rooms, bright highlights, and vivid colors, so your content looks life-like. It even has some neat features to help with productivity, like a USB hub to which you can connect various devices, and a KVM switch. However, the main downside is that it risks burn-in with constant exposure to the same static elements over time, which can be problematic if you always have your editing program open.

Differences Between Sizes And Variants
We bought and tested the 27-inch ASUS XG27ACDNG, which is the only size available, and the results are only valid for this model. ASUS has other 27-inch OLEDs, like the ASUS ROG Swift OLED PG27UCDM and the ASUS ROG Strix OLED XG27AQDMG, but they're different monitors with different specs.
| Name | Size | Resolution | Refresh Rate | Panel Type |
|---|---|---|---|---|
| XG27ACDNG | 27" | 1440p | 360Hz | QD-OLED |
Our unit's label indicates it was manufactured in August 2024. We tested it on firmware MCM102.
Popular Monitor Comparisons
The ASUS XG27ACDNG is a premium gaming monitor with a 1440p resolution, 360Hz refresh rate, and QD-OLED panel. It competes against other monitors with the same specs, like the MSI MPG 271QRX QD-OLED, Gigabyte AORUS FO27Q3, and the Dell Alienware AW2725DF. It performs as expected for a high-end monitor, with sharp motion handling, low input lag, and outstanding picture quality, and it even gets brighter than its competition. Plus, it has a few handy features to connect various devices, like a USB hub with a USB-C port and a KVM switch. If you're looking for a QD-OLED monitor with these specs, it's worth getting if you can find it for less than the competition.

The ASUS ROG Strix OLED XG27ACDNG is a higher-end model than the ASUS ROG Strix OLED XG27AQDMG. There are a few differences, mainly due to their specs and panel types. The XG27ACDNG has a higher 360Hz refresh rate and a few extra features, like HDMI 2.1 bandwidth, a KVM switch, and a USB-C port. The XG27ACDNG also uses a QD-OLED panel with more vivid colors. On the other hand, the XG27AQDMG gets a bit brighter in HDR, and its WOLED panel is better to use in bright rooms, as blacks don't look as purple as on the XG27ACDNG.
The MSI MPG 271QRX QD-OLED and the ASUS ROG Strix OLED XG27ACDNG are competing monitors with similar specs as they each have a 1440p, 360Hz QD-OLED screen. The main advantage of the ASUS is that it gets brighter in SDR, so it's the better choice if you need something to use in a bright room. Besides that, the MSI has slightly better motion handling, but the difference is hard to tell.
The Gigabyte MO27Q28G is a slightly better monitor than the ASUS ROG Strix OLED XG27ACDNG. The Gigabyte gets a lot brighter, so it can handle more glare in a bright room, and it delivers a more impactful HDR experience. The ASUS has better color volume, though, as very bright colors are slightly washed out on the Gigabyte. The ASUS also has a higher max refresh rate, which helps improve motion clarity a bit.
The ASUS ROG Strix OLED XG27ACDNG and the Samsung Odyssey OLED G60SD S27DG602S are both QD-OLEDs with a 1440p resolution and 360Hz refresh rate. They perform similarly, but there are a few differences. The ASUS has a few extra features, like a USB-C port and KVM switch, that make it easy to multitask, and it has better compatibility with gaming consoles, too. However, choosing one over the other may depend on which screen coating you prefer. The ASUS has a glossy coating that results in a clearer image, but stronger direct reflections, while the matte coating on the Samsung does a better job at diffusing light, but the image is hazier.
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.
