The ASUS ROG Strix XG27UQR is a 27-inch, 4k monitor that's an updated model of the ASUS ROG Strix XG27UQ. First released in 2021, it's designed with PC gamers in mind as it has a 144Hz refresh rate with FreeSync variable refresh rate (VRR) support and G-SYNC compatibility. However, unlike many 4k gaming monitors, it lacks HDMI 2.1 bandwidth and can't take advantage of current-gen gaming consoles like the PS5 and Xbox Series X|S or HDMI 2.1 graphics cards. Besides that, it has features you'd expect to find in a gaming monitor, like crosshairs and a Shadow Boost feature to make it easier to spot opponents in dark games, and it also has a USB hub that lets you charge your devices while gaming.

Our Verdict

8.0 Mixed Usage

The ASUS ROG Strix XG27UQR is great for most uses. It's designed with gaming in mind, and it's great for that use, as it has a 144Hz refresh rate with VRR support. It also has a quick response time at high refresh rates and low input lag for a responsive feel. However, it can't take full advantage of current-gen gaming consoles because it doesn't support HDMI 2.1 bandwidth. Besides that, its 27-inch, 4k screen offers plenty of detail with sharp text, which makes it great for the office or media creation, and it gets bright enough to fight glare in well-lit rooms. It's also good for watching multimedia content thanks to this high resolution, but with a low contrast ratio and terrible local dimming feature, it struggles in dark rooms.

Pros
  • Sharp text and image clarity.
  • High SDR peak brightness.
  • Wide viewing angles.
  • Quick response time at high refresh rates.
Cons
  • Some motion blur, particularly at low refresh rates.
  • Lacks HDMI 2.1 bandwidth; not fully compatible with PS5 and Xbox Series X|S.
  • Low contrast ratio.
8.2 Office

The ASUS XG27UQR is great for the office. The 27-inch screen is big enough for multitasking with different windows open, and the 4k resolution provides a high pixel density, which results in sharp text clarity. It's also a great choice in bright rooms because it has high peak brightness and decent reflection handling, so visibility isn't a problem. Lastly, its wide viewing angles make it good to use if you need to show your screen to a coworker next to you as the image remains consistent from the sides, and it offers swivel adjustments.

Pros
  • Sharp text and image clarity.
  • High SDR peak brightness.
  • Wide viewing angles.
  • 27-inch screen big enough for multiple windows.
Cons
  • Can't rotate into portrait mode.
  • Big bezels; not ideal for a multi-monitor setup.
8.1 Gaming

The ASUS ROG Strix XG27UQR is great for PC gaming. It supports VRR through FreeSync and G-SYNC compatibility to reduce screen tearing and has a max refresh rate of 144Hz. Motion looks good thanks to its quick response time at high refresh rates, but there's still some blur, especially at low refresh rates. Luckily, it has low input lag, and you won't notice any delay, even during reaction-based games. Unfortunately, it can't take full advantage of the PS5 and Xbox Series X|S because it lacks HDMI 2.1 bandwidth, so you can't play 4k @ 120Hz games on them.

Pros
  • Sharp text and image clarity.
  • 144Hz refresh rate.
  • Quick response time at high refresh rates.
  • Low input lag.
  • VRR works without issue over DisplayPort.
Cons
  • Some motion blur, particularly at low refresh rates.
  • Lacks HDMI 2.1 bandwidth; not fully compatible with PS5 and Xbox Series X|S.
  • Low contrast ratio.
7.7 Media Consumption

The ASUS XG27UQR is good for media consumption. The 4k resolution lets you watch the latest 4k shows and movies with a ton of detail, and the 27-inch screen is big enough if you need to watch something with a friend sitting next to you. It also gets very bright, which is great if you want to watch content in a bright room, and it has decent reflection handling. However, it's worse to use in a dark room because it has a low contrast that makes blacks look gray, and its terrible local dimming feature doesn't do much to improve the picture quality in dark scenes.

Pros
  • Sharp text and image clarity.
  • High SDR peak brightness.
  • Wide viewing angles.
Cons
  • Low contrast ratio.
  • Terrible local dimming feature.
8.3 Media Creation

The ASUS ROG Strix XG27UQR is good for content creators. It has a dedicated sRGB mode that results in good accuracy before calibration, but the mode also locks some picture settings. Its 4k resolution provides a ton of detail and delivers sharp images thanks to its high pixel density. It also has wide viewing angles, which is ideal if you have a coworker or client sitting next to you and they need to see an accurate image. It also offers swivel adjustment, but you can't rotate it into portrait mode.

Pros
  • Sharp text and image clarity.
  • High SDR peak brightness.
  • Wide viewing angles.
  • 27-inch screen big enough for multiple windows.
Cons
  • Can't rotate into portrait mode.
  • Low contrast ratio.
7.0 HDR

The ASUS XG27UQR is alright for HDR, but it has its limitations. While it displays a wide range of colors and has good HDR peak brightness, highlights don't pop against the rest of the image as it has a low contrast ratio. This means that blacks look gray, and even though it has a local dimming feature, it does a terrible job of improving the black levels.

Pros
  • Displays wide range of colors in HDR.
Cons
  • Low contrast ratio.
  • Terrible local dimming feature.
  • Highlights don't pop against the rest of the image.

Differences Between Sizes And Variants

We tested the 27-inch ASUS XG27UQR, which is the only size available for this monitor, and it's an updated version of the ASUS ROG Strix XG27UQ. Similar monitors are available from ASUS, including the ASUS ROG Swift PG32UQR, but the results from this monitor aren't valid for any of those.

Size Name Resolution Refresh Rate Panel Type HDMI 2.1
27" XG27UQR 4k 144Hz IPS No

Our unit was manufactured in January 2023; you can see the label here.

Compared To Other Monitors

The ASUS XG27UQR is a great 4k gaming monitor that falls short of the competition. It lacks HDMI 2.1 bandwidth found on many of its competitors, and it isn't much of a difference from the older ASUS ROG Strix XG27UQ. While it doesn't cost much for a 4k gaming monitor, you can get more value in similarly-priced monitors.

See our recommendations for the best 4k gaming monitors, the best 4k 144Hz monitors, and the best 27-inch gaming monitors.

ASUS ROG Strix XG27AQ

The  ASUS ROG Strix XG27UQR and the ASUS ROG Strix XG27AQ are different gaming monitors. The XG27UQR has a higher 4k resolution that delivers more detail with sharper images, while the XG27AQ has a slightly higher 170Hz refresh rate. However, the XG27AQ also has better motion handling thanks to its quicker response time, meaning it's the better choice for fast-paced games.

LG 27GP950-B

The LG 27GP950-B is a better gaming monitor than the ASUS ROG Strix XG27UQR. The main advantage is that it supports HDMI 2.1 bandwidth, which the ASUS model doesn't have, and it lets you take full advantage of gaming consoles or HDMI 2.1 graphics cards. The LG also has better motion handling, particularly at lower refresh rates. However, the ASUS gets brighter and has better reflection handling, making it the better choice for well-lit rooms.

ASUS ROG Strix XG27UQ

The ASUS ROG Strix XG27UQR is an updated version of the ASUS ROG Strix XG27UQ. While they have different stands with better ergonomics on the XG27UQ, they're very similar in features and performance. The XG27UQR has the same 144Hz refresh rate with HDMI 2.0 bandwidth as the XG27UQ and has the same selection of inputs. The main advantage the XG27UQR has is its slightly improved color gamut; other than that, they're very similar monitors.

Sony INZONE M9

The Sony INZONE M9 is better for gaming than the ASUS ROG Strix XG27UQR. The Sony supports HDMI 2.1 bandwidth, which lets it take full advantage of gaming consoles or HDMI 2.1 graphics cards, and the ASUS doesn't support this. The picture quality on the Sony is also better thanks to its superior local dimming and HDR brightness, meaning that highlights stand out more. The Sony also has better motion handling, especially at lower refresh rates.

Contrast With Local Dimming
1,033 : 1

The ASUS XG27UQR has a mediocre contrast ratio that fails to make blacks look deep and inky next to bright highlights, especially when viewed in a dark environment. Enabling the local dimming feature doesn't improve the contrast either. Contrast With Local Dimming results with the screen at 450 cd/m² of brightness instead of the 100 cd/m² that we target for testing because local dimming locks the brightness to its max. This means that local dimming raises the brightness of the entire image, including the black levels.

Picture Quality
Local Dimming
Local Dimming

Edge

The local dimming feature is terrible. It's edge-lit with 16 zones, and most content causes all the zones to turn on, effectively making the local dimming feature useless. The black level is elevated, which means there isn't any black crush, but you lose a lot of details in darker scenes. Because all the zones are on most of the time, there isn't much blooming unless there's a small object against a dark background that causes only a few zones to light up. This happens with subtitles sometimes, which could get distracting. The setting for local dimming is called Dynamic Dimming, which you can turn on or off in SDR, but it's locked on in HDR.

The SDR brightness is excellent. It easily gets bright enough to fight glare, and you won't have issues using it in a bright room. It also maintains the brightness consistent across different scenes. However, the minimum brightness may be a bit too high if you want to use your monitor in a dark environment and are sensitive to light. The results are from after calibration with the following settings:

  • Game Visual: User Mode
  • Brightness: 100
  • Contrast: 80
  • Dynamic Dimming: Off

The HDR brightness is good, but because of the low contrast and terrible local dimming feature, highlights don't pop against the rest of the image. Besides some raised blacks in really dark scenes, it displays content at its intended brightness until there's a sharp cut-off at its peak brightness, meaning it lets your PC or source do any tone mapping. These results are with ASUS Gaming HDR enabled, which locks all other settings, and keeps local dimming on.

The black uniformity is okay. There's clouding throughout, and blacks look blue due to the low contrast. As you can see, the local dimming feature doesn't actually improve the black levels, and because it forces the brightness to its max, the image appears brighter.

The accuracy before calibration is impressive. The dedicated sRGB mode locks colors well to the sRGB color space, so they aren't oversaturated, but there are still some inaccurate colors, particularly reds and yellows. The white balance is also off with brighter shades, but it isn't terrible. Luckily, the color temperature is very close to the 6500K target, and gamma follows the sRGB curve almost perfectly.

Unfortunately, using the sRGB mode locks the brightness, causing the screen to be dim. Other settings are locked, too, including Aspect Control. If you want to change those settings, you need to use another mode that's less accurate with a warmer color temperature and oversaturated colors, as you can see here.

The response time at 60Hz is alright, but there's more noticeable blur trail with fast-moving objects than at higher refresh rates. The 'Level 1' overdrive setting is the best because the higher settings have too much overshoot. This means you may need to change the overdrive setting if the frame rate of your game drops or if you change sources.

The ASUS ROG Strix XG27UQR has an optional backlight strobing feature to reduce persistence blur, but it isn't that effective. It only works within a narrow refresh rate range and locks you out of overdrive settings. The timing is also off, causing image duplication with fast-moving objects.

The backlight remains flicker-free with the brightness at its max, but then it uses pulse width modulation (PWM) to dim its backlight with the brightness setting at anything below the max. However, you likely won't notice it because it's such a high flicker frequency of around 26,000Hz. The backlight is also flicker-free in HDR as the brightness is locked to its max.

The ASUS XG27UQR works well with the Xbox Series X|S but doesn't support 4k @ 120Hz signals as it lacks HDMI 2.1 bandwidth. Even though the monitor supports FreeSync, it doesn't work with the console.

macOS Compatibility

The ASUS ROG Strix XG27UQR works well with macOS, but there are some limitations. The maximum refresh rate with a USB-C to DisplayPort adapter is 80Hz, but VRR works well. As this monitor supports HDMI 2.0 bandwidth, you're limited to 4k @ 60Hz signals over HDMI, even on newer Mac computers that support HDMI 2.1. If you're using a MacBook, windows return to their original position when waking it up from sleep or reopening the lid.

The ASUS ROG Strix XG27UQR has a few extra features, including:

  • Aspect Control: Changes the aspect ratio of the image between 16:9 and 4:3.
  • Blue Light Filter: Reduces blue light to help reduce eye strain.
  • Crosshair: Displays a virtual crosshair that your games' anti-cheat tools won't detect, giving you a competitive advantage.
  • Lighting Effect: Controls the RGB lighting in the back. You can choose from presets with Aura RGB and even sync the colors to the content on screen with the downloadable Armoury Crate program.
  • Shadow Boost: Changes the gamma so that it's easier to see opponents in dark areas of games.
