The ASUS ROG Strix XG27UQ is an excellent 4k gaming monitor. Its large 27 inch screen displays razor-sharp images and text, and it has good ergonomics and decent viewing angles, making it suitable for a wide range of uses. It has a fast response time, low input lag, and a 144Hz refresh rate, resulting in smooth motion and incredible responsiveness. However, it requires a graphics card with Display Stream Compression and a DisplayPort connection to achieve such a high refresh rate since it lacks an HDMI 2.1 port. It supports Adaptive Sync and is compatible with FreeSync and G-SYNC. Its IPS panel has decent reflection handling and gets bright enough to combat intense glare. It isn't as well-suited for dark rooms, though, as its low contrast ratio makes blacks look grayish. It has a good wide color gamut and gets decently bright in HDR, but the local dimming is terrible and can be quite distracting.

Our Verdict

8.3 Mixed Usage

The ASUS ROG Strix XG27UQ is a great monitor overall. It has a large 4k screen that makes it suitable for work, gaming, or media consumption. Gaming feels responsive due to its low input lag and high refresh rate, and it has a fast response time and a Black Frame Insertion feature to deliver clear images. It has an outstanding SDR color gamut for viewing and creating content, but the contrast ratio is low, resulting in blacks that look gray in the dark.

Pros
  • Large screen and 4k resolution.
  • Good visibility in bright rooms.
  • Good ergonomics.
Cons
  • Mediocre contrast ratio.
  • Images look washed out when viewed from the side.
8.2 Office

The ASUS ROG Strix XG27UQ's design is almost identical to the ASUS ROG Strix XG279Q but with thick borders on all four sides. It has a tripod-style stand with an LED light that shines onto the desk, which you can customize with the included acrylic covers to show the ROG logo. There's a larger ROG logo on the back that also lights up. You can control the color and lighting effects of both lighting zones with ASUS' Aura Sync software.

Build Quality

The ASUS XG27UQ's build quality is great. The stand's feet are metal while the column is plastic. It's very heavy and doesn't wobble. The back is also made of sturdy plastic, and the adjustment hinges are of good quality, although the plastic covering them feels a bit flimsy. There aren't any loose parts or obvious gaps in the construction, and most people shouldn't have any issues with it.

The ASUS XG27UQ has a mediocre contrast ratio, resulting in blacks that look grayish when viewed in a dark room. It's slightly higher than the advertised 1000:1; however, contrast can vary between individual units. The local dimming feature doesn't improve the black level at all, and enabling it locks the screen's brightness to max automatically.

Edge

The ASUS ROG Strix XG27UQ has a terrible local dimming feature. It's called Dynamic Dimming in the on-screen settings menu. It's edge-lit, and there are eight vertical lighting zones. Zone transition is relatively fast but not smooth, so it's very visible. However, it isn't noticeable with small objects, as it seems like it requires an object of a certain size to trigger the local dimming. There's no black crush because the black level is raised when a zone lights up. There's a lot of blooming due to the large vertical zones, but blooming around subtitles isn't really noticeable in regular content since most of the zones are on all the time. It can be distracting in dark scenes when only a few zones are lit, as the difference in contrast between the zones that are on and those that are off is very drastic.

Decent HDR peak brightness. It's higher than the advertised 400 cd/m² and meets its DisplayHDR 400 certification requirement. It's very consistent when displaying different content, but unlike in SDR, there's a bit of dimming in the 2% window, so small highlights in dark scenes don't pop as much. It can make some highlights stand out, although it's more noticeable in a dark room than in a bright one.

We measured the HDR peak brightness in the 'ASUS Gaming HDR' Picture Mode.

The ASUS ROG Strix XG27UQ has a good HDR color gamut. It has excellent coverage of the DCI P3 color space used in most content and decent coverage of the wider Rec. 2020.

Our measurement of the DCI P3 coverage is slightly lower than the advertised 90% coverage due to how we measure it. We measure it by sending a Rec. 2020 signal, but unlike most reviewers, we limit the colors to the DCI P3 primaries. This results in a lower but arguably more accurate measurement.

The ASUS ROG Strix XG27UQ has outstanding response time at its max refresh rate, resulting in only a short blur trail behind fast-moving objects. Our recommended overdrive setting is 'Level 3' as it provides the best performance without causing too much overshoot like the 'Level 4' and 'Level 5' options. The LG 27GP83B-B has a slightly faster max refresh rate, and a slightly faster response time.

The ASUS ROG Strix XG27UQ has a high refresh rate that results in a more fluid and responsive gaming experience. However, you can only achieve the full 144Hz with a graphics card that supports Display Stream Compression and over a DisplayPort connection since it lacks an HDMI 2.1 port. It supports Adaptive Sync to reduce screen tearing, and it's compatible with both FreeSync and G-SYNC. G-SYNC only works over a DisplayPort connection, and FreeSync's range is 20-120Hz over DisplayPort and 20-60Hz over HDMI. If you need something with an HDMI 2.1 port, then look into the Acer Nitro XV282K KVbmiipruzx or the Gigabyte M28U.

The ASUS ROG Strix XG27UQ has an exceptionally low input lag. We don't have an input lag measurement with VRR enabled as there's a bug preventing us from running the test at 144Hz with VRR. We're investigating this issue, and we'll provide an update once it's resolved. That said, we don't expect it to be much higher than when it's disabled. We don't have a measurement for 10-bit HDR because we lack the tools to measure the input lag with 10-bit HDR over a DisplayPort connection, and we can only achieve a 4k @ 60Hz signal at 8-bit over HDMI.

Compared To Other Monitors

The ASUS ROG XG27UQ is an excellent gaming monitor that's also well-suited for productivity and media consumption. It's one of the best high-refresh 4k monitors on the market, but it comes with a high price tag, and its 144Hz refresh rate is only achievable with a graphics card that supports Display Stream Compression. For other options, check out our recommendations for the best 4k gaming monitors, the best HDR gaming monitors, and the best 144Hz monitors.

LG 27GN950-B

Overall, the ASUS ROG Strix XG27UQ and the LG 27GN950-B are very similar, but the LG has a slightly higher refresh rate of 160Hz. The ASUS is better a choice if you need swivel adjustments, and it has better reflection handling for gaming in a bright room. It has a Black Frame Insertion feature that the LG doesn't have, but it causes slight image duplication and may not be to everyone's liking. The LG has wider viewing angles that are more ideal for sharing content or playing co-op games, and it gets a lot brighter in HDR, although the brightness isn't as consistent. It has a faster response time as well, which results in clearer images in fast-moving scenes.

Samsung Odyssey G7 LC32G75T

The ASUS ROG Strix XG27UQ is a bit better than the Samsung Odyssey G7 LC32G75T. The ASUS has a higher 4k resolution, wider viewing angles, and its brightness is more consistent across different content. However, the Samsung has a higher contrast ratio to produce deeper blacks, faster response time, and a higher 240Hz refresh rate.

Acer Nitro XV282K KVbmiipruzx

The ASUS ROG Strix XG27UQ and the Acer Nitro XV282K KVbmiipruzx are both excellent 4k gaming monitors. Even though they each have a 144Hz refresh rate, you can only reach that refresh rate over HDMI with the Acer because it has HDMI 2.1 inputs while the ASUS has HDMI 2.0. The Acer has native FreeSync support, which the ASUS doesn't, but their VRRs work with NVIDIA and AMD graphics cards. The ASUS gets much brighter in SDR, making it a better choice for well-lit rooms.

ASUS ROG Strix XG279Q

The ASUS ROG Strix XG27UQ is a bit better than the ASUS ROG Strix XG279Q. The XG27UQ has a much lower input lag when playing at 60Hz, gets brighter to combat glare, and its 4k resolution results in better text clarity. The XG279Q has a faster response time, a higher refresh rate, wider viewing angles, and better reflection handling.

Acer Predator XB273K Pbmiphzx

Overall, the ASUS ROG Strix XG27UQ is better than the Acer Predator XB273K Pbmiphzx. The ASUS has better ergonomics, higher peak brightness in SDR and HDR, and even though its response time is slower, it has much less overshoot. The Acer has better reflection handling, more USB ports, and a pair of speakers. The ASUS has native Adaptive-Sync support and is compatible with FreeSync and G-SYNC, while the Acer is a native G-SYNC monitor.

Gigabyte M28U

The ASUS ROG Strix XG27UQ and the Gigabyte M28U are very similar overall, but the ASUS is slightly better for most people. The ASUS has better ergonomics, lower input lag, and it's brighter. The Gigabyte has slightly better reflection handling, and its black frame insertion feature is a bit more versatile, as it works across a wider range of refresh rates.

Samsung Odyssey G9

The ASUS ROG Strix XG27UQ scores higher overall than the Samsung Odyssey G9; however, they're very different monitors. The ASUS is a 4k monitor with a 16:9 aspect ratio and a 144Hz refresh rate, while the Samsung is a 32:9 1440p monitor with a 240Hz refresh rate. The ASUS has much wider viewing angles and better response time. The Samsung has a VA panel with a much higher contrast ratio, and it gets a lot brighter in HDR.

LG 48 CX OLED

Although the ASUS ROG Strix XG27UQ and the LG 48 CX OLED score similarly overall, they're very different types of displays. The ASUS is an IPS monitor with a slightly higher refresh rate, lower input lag, and higher peak brightness. It allows for ergonomic adjustments, which the LG doesn't offer, and its smaller screen results in a higher pixel density, so images and text look sharper. On the other hand, the LG has an OLED panel that can produce perfect blacks, making it better for dark rooms. It also has faster response time and supports HDMI 2.1. Although the LG has wider viewing angles, colors shift quickly when moving off-center, so it isn't ideal for content creation.

LG 27GP83B-B

The ASUS ROG Strix XG27UQ is better than the LG 27GP83B-B for the most part, but some people might still prefer the LG. The ASUS has better ergonomics and much better text clarity, and it has an optional black frame insertion feature. On the other hand, the LG has better reflection handling, a faster refresh rate, and a better response time. The ASUS has a higher resolution screen, but this may actually be a downside for some gamers, as it's more taxing on your PC. If you prefer fast-paced, smooth motion, get the LG, but if you prefer a higher resolution, get the ASUS.
