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

9.2 PC Gaming

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.

Pros
  • Small highlights pop in HDR.

  • Motion looks extremely sharp.

  • Deep and inky blacks.

  • 360Hz refresh rate and VRR support.

  • Low input lag.

Cons
  • Larger highlights are dimmer.

  • Distracting VRR flicker.

  • Ambient light causes black levels to rise.

9.1 Console Gaming

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.

Pros
  • Small highlights pop in HDR.

  • Motion looks extremely sharp.

  • Deep and inky blacks.

  • Low input lag.

  • HDMI 2.1 bandwidth.

Cons
  • Larger highlights are dimmer.

  • Ambient light causes black levels to rise.

  • Needs to downscale 4k signals.

7.9 Office

The ASUS XG27ACDNG is good for office use, but it has some limitations. It gets bright enough to fight glare in most well-lit offices and has fantastic 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.

Pros
  • Bright enough to fight glare.

  • USB hub and KVM switch.

  • Versatile ergonomics.

Cons
  • Risk of burn-in.

  • Some fringing around text.

8.9 Editing

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, 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.

Pros
  • Bright enough to fight glare.

  • Deep and inky blacks.

  • Accurate sRGB mode.

  • USB hub and KVM switch.

  • Versatile ergonomics.

Cons
  • Needs calibration for best accuracy.

  • Ambient light causes black levels to rise.

  • Risk of burn-in.

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.

NameSizeResolutionRefresh RatePanel Type
XG27ACDNG27"1440p360HzQD-OLED

Our unit's label indicates it was manufactured in August 2024. We tested it on firmware MCM102.

Compared To Other Monitors

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.

Also, see our recommendations for the best high refresh rate monitors, the best ASUS monitors, and the best HDR gaming monitors.

ASUS ROG Strix OLED XG27AQDMG

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.

MSI MPG 271QRX QD-OLED

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.

Gigabyte AORUS FO27Q3

The ASUS ROG Strix OLED XG27ACDNG and the Gigabyte AORUS FO27Q3 are both 1440p, 360Hz QD-OLEDs that compete against each other. They perform similarly and even have many of the same features, including a USB hub and KVM switch, but the USB-C port on the ASUS delivers more power than that on the Gigabyte.

Dell Alienware AW2725DF

The Dell Alienware AW2725DF and the ASUS ROG Strix OLED XG27ACDNG are competing 1440p, 360Hz monitors with QD-OLED panels. They're similar in terms of performance, but the ASUS has a few advantages when it comes to features. The ASUS has HDMI 2.1 bandwidth that lets you take full advantage of modern graphics cards and gaming consoles. It also has a KVM switch that makes it easy to multitask, and its USB-C port supports DisplayPort Alt Mode, so you can display an image from your laptop. On top of that, the ASUS' higher brightness makes it a better choice to use in bright rooms.

Samsung Odyssey OLED G60SD S27DG602S

The ASUS ROG Strix OLED XG27ACDNG and the Samsung Odyssey OLED G6/G60SD S27DG60 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.

This monitor 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. It gets a bit brighter with VividPixel on its max of '100', but it also introduces some artifacts. With Uniform Brightness off, there's some variation in brightness between different content, but it isn't enough to be distracting. However, if that bothers you, it's better to enable Uniform Brightness, for which you can see the results below:

The HDR brightness is okay. While small highlights really pop against the rest of the image, it can't sustain this brightness with larger highlights, as they don't pop as much. It also has some issues with PQ EOTF tracking, as there's a slow roll-off before the peak brightness, so it doesn't let highlights get as bright as possible.

The accuracy before calibration in the sRGB color space is excellent. It locks colors fairly well to the sRGB color space, and although some primary colors are still slightly oversaturated, you likely won't notice this. On top of that, most colors, the color temperature, and the white balance are still accurate, but gamma tracking is a bit darker than intended.

Using the 'sRGB Cal Mode' GameVisual locks a few settings, which are listed below. That said, if you want to use another mode that gives you more access to these settings, then colors are more oversaturated.

Triangular RGB

The text clarity is decent. It isn't as good as 27-inch, 1440p monitors with IPS panels due to the fact that programs don't render text well with the triangular subpixel layout. Enabling Windows ClearType (top photo) makes text sharper, though. These photos are in Windows 10, and you can also see them in Windows 11 with ClearType on and with ClearType off.

Due to the triangular subpixel layout, there's some color fringing around letters and at the edge of windows, though it's hard to see unless you look closely at the monitor. Whether or not you notice it or it bothers you changes from person to person, and it depends on how sensitive you are to this subpixel layout.

The ASUS XG27ACDNG has a black frame insertion feature to reduce persistence blur, but it's limited in how you can use it. It only works with limited refresh rates, and you can't use it at the same time as a few features, including VRR. It also locks the Brightness to '70'.

The ASUS XG27ACDNG has noticeable VRR flicker with changing frame rates, which is most distracting in dark scenes. You can avoid this issue by setting a frame rate cap or if your PC can maintain consistent frame rates.

There's an OLED Anti-Flicker setting that's meant to reduce flicker, but it only works over DisplayPort and actually disables VRR. It only works with fixed 360Hz, 120Hz, 100Hz, and 60Hz signals. Instead of having VRR flicker, it introduces stuttering and screen tearing.

The backlight isn't technically flicker-free because it has a slight dip in brightness that corresponds to the 360Hz refresh rate.

Besides the fact that it needs to downscale 4k signals, there aren't any compatibility issues with the PS5 or PS5 Pro.

The ASUS XG27ACDNG works well with macOS, and there aren't any issues with HDR or VRR. If you're using a MacBook with an HDMI connection, closing the lid puts the monitor to sleep, and when you open it again, windows return to their original position. That said, you can continue working on the monitor with a USB-C connection when you close the lid.

This monitor has a ton of extra features to improve your gaming experience, including:

  • Aspect Control: You can change the display area to simulate a 24.5-inch image or a 4:3 aspect ratio.
  • Blue Light Filter: Reduces blue light to help reduce eye strain.
  • GamePlus: Includes the following gaming features: FPS Counter, Crosshair, Sniper, Timer, Stopwatch, and Display Alignment.
  • Lighting Effect: Offers settings to control the monitor's RGB lighting, like Aura Sync and Aura RGB.
  • PIP/PBP: Has settings to adjust the picture-in-picture and picture-by-picture modes.

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.
  • 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. It also has an OLED Usage Info setting to show how many times the cleaning cycle has been performed.
  • Screen Move: Moves the image by a few pixels at a time so that pixels aren't always displaying the same thing.
  • Auto Logo Brightness: Dims static logos on the screen.
