The ASUS ROG Swift PG27UQR is a mid-range 27-inch, 4k gaming monitor. Part of the ROG Swift gaming lineup, it's a higher-end model than the ASUS ROG Strix XG27UQR, with a faster 160Hz refresh rate, and it has other gaming features like FreeSync variable refresh rate (VRR) support and G-SYNC compatibility. It competes with other 4k gaming monitors, like the Gigabyte M32U. It offers a healthy selection of ports with HDMI 2.1, DisplayPort 1.4, and USB-A ports. It also includes a few handy features to improve your gaming experience, like crosshairs and ELMB Sync for its backlight strobing feature to work simultaneously with VRR.

Our Verdict

8.2 Mixed Usage

The ASUS PG27UQR is great for most uses. It's excellent for gaming thanks to its fast response time, low input lag at high refresh rates, and HDMI 2.1 bandwidth to take full advantage of gaming consoles and modern graphics cards. It's also impressive for office use and content creation as it displays sharp text and detailed images, and its wide viewing angles and good ergonomics are ideal for sharing your screen with someone else. It's good for watching content, especially in a bright room, as it gets bright and has good reflection handling, but it looks worse in dark rooms due to its low contrast ratio and terrible local dimming feature.

Pros
  • Sharp text clarity.
  • Good ergonomics.
  • Wide viewing angles.
  • Performs well in bright rooms.
Cons
  • Not many extra office features like a KVM switch.
  • Input lag increases with 60Hz signals.
8.4 Office

The ASUS PG27UQR is impressive for office use. Its 4k resolution and high pixel density helps result in sharp text, and its 27-inch screen is big enough to place two windows side-by-side. It also has decent viewing angles and good ergonomics, making it easier to share your screen with a coworker. Lastly, you won't have issues using it in a well-lit room as it gets bright enough to fight glare and has good reflection handling.

Pros
  • Sharp text clarity.
  • Good ergonomics.
  • Wide viewing angles.
  • Performs well in bright rooms.
Cons
  • Not many extra office features like a KVM switch.
8.7 Gaming

The ASUS PG27UQR is excellent for gaming. It has smooth motion handling at any refresh rate thanks to its fast response time, and it has low input lag at high refresh rates. However, its input lag increases at 60Hz, which is disappointing if you're a competitive gamer who relies on fast reactions. On the plus side, it has a max 160Hz refresh rate and HDMI 2.1 bandwidth to take advantage of current-gen gaming consoles and modern graphics cards. It also has FreeSync VRR and G-SYNC compatibility to reduce screen tearing.

Pros
  • Excellent motion handling at any refresh rate.
  • HDMI 2.1 bandwidth.
  • 160Hz refresh rate with VRR support.
  • Low input lag at high refresh rates.
  • 4k resolution delivers detailed images.
Cons
  • Low contrast ratio.
  • Input lag increases with 60Hz signals.
7.7 Media Consumption

The ASUS PG27UQR is good for media consumption. Its 4k resolution lets you watch the latest content with a ton of details, and it produces sharp images. It's good if you want to watch content with a friend next to you as it has wide viewing angles and good ergonomics that make it easy to adjust. It's also ideal for watching content in bright rooms thanks to its high peak brightness, but it struggles in dark rooms as it has a low contrast ratio that makes blacks look gray.

Pros
  • Sharp text clarity.
  • Wide viewing angles.
  • Performs well in bright rooms.
Cons
  • Low contrast ratio.
  • Terrible local dimming feature.
8.4 Media Creation

The ASUS PG27UQR is impressive for media creation. Its dedicated sRGB mode results in excellent accuracy but also limits the brightness, so you'll need to calibrate the monitor if you want a bright and accurate image. Besides that, its 4k resolution results in detailed images, and its 27-inch screen is big enough to multitask with two windows open. Its good ergonomics are also useful if you need to share your screen with a coworker or client, and it has wide viewing angles that keep the image consistent from the sides.

Pros
  • Good ergonomics.
  • Wide viewing angles.
  • 4k resolution delivers detailed images.
  • Excellent accuracy.
Cons
  • Not many extra office features like a KVM switch.
  • sRGB mode limits brightness.
7.0 HDR

The ASUS PG27UQR is decent for HDR. It gets very bright in HDR, but small highlights don't pop against the rest of the image, so some HDR content looks muted. It also displays a wide range of colors, but not all colors are as bright and vivid as they should be. Unfortunately, it has a low contrast ratio that makes blacks look gray, and its local dimming feature is terrible as it doesn't improve the contrast ratio.

Pros
  • 4k resolution delivers detailed images.
  • Great HDR brightness.
Cons
  • Low contrast ratio.
  • Terrible local dimming feature.
  • Small highlights are muted.

Differences Between Sizes And Variants

We tested the 27-inch ASUS PG27UQR, which is part of the ROG Swift gaming lineup. It has a black body, but it's also available as the PG27UQR-W with a white body. While similar monitors are available, for which you can see the differences below, the results are only valid for this monitor.

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

Compared To Other Monitors

The ASUS PG27UQR is an excellent mid-range 4k gaming monitor with HDMI 2.1 bandwidth and smooth motion handling. It competes well with other 4k gaming monitors, and it's competitively priced, so it offers great value against the competition. It's a better choice than the Gigabyte M32U if you need something for gaming at high refresh rates, thanks to its fast response time, but its increased input lag at 60Hz is disappointing if you play games at lower refresh rates. Also, it has fewer productivity features than the M32U or the Gigabyte M27U, so if you need something versatile, those are still better choices. It doesn't have as good picture quality as the Samsung Odyssey Neo G7 S32BG75, but that's a premium monitor that costs more anyway.

See our recommendations for the best 4k gaming monitors, the best 27-inch gaming monitors, and the best monitors for PS5/PS5 Pro.

LG 27GP950-B

The ASUS ROG Swift PG27UQR and the LG 27GP950-B are both excellent 4k gaming monitors. They have many similarities, especially in their performance, but the LG has a lower input lag at 60Hz for a more responsive feel. However, most of their differences are minor, as the ASUS has a more ergonomic stand and better reflection handling, making it the better choice for well-lit rooms.

Gigabyte M27U

The ASUS ROG Swift PG27UQR and the Gigabyte M27U are similar 4k gaming monitors, with a few differences. The ASUS has a slightly higher 160Hz refresh rate and better motion handling at lower refresh rates. However, the Gigabyte has a lower input lag at 60Hz for a more responsive feel. The ASUS comes with a more ergonomic stand that offers swivel adjustments, which the Gigabyte doesn't have; however, the Gigabyte has a few extra features like a KVM switch and USB-C port, so it's the slightly better choice for productivity.

ASUS ROG Strix XG27UQR

The ASUS ROG Swift PG27UQR is a higher-end monitor than the ASUS ROG Strix XG27UQR, so it has a few extra features. The main difference is that the PG27UQR has HDMI 2.1 bandwidth, which the XG27UQR doesn't have, so it can take full advantage of current-gen gaming consoles and modern graphics cards. The PG27UQR also has a more modern look with thinner bezels and a more ergonomic stand. Lastly, the PG27UQR has a slightly higher refresh rate and much better motion handling across its entire refresh rate range.

LG 27GR93U-B

The ASUS ROG Swift PG27UQR and the LG 27GR93U-B are both excellent 4k gaming monitors. The ASUS has a slightly higher 160Hz refresh rate compared to 144Hz on the LG, but the motion handling is similar between each. The LG does have an advantage with input lag though, as it has lower input lag at 60Hz than the ASUS. The LG gets brighter in SDR and has slightly better reflection handling, so it's better to use in bright rooms, but the ASUS has improved HDR peak brightness.

Samsung Odyssey Neo G8 S32BG85

The Samsung Odyssey Neo G8 S32BG85 and the ASUS ROG Swift PG27UQR are different types of 4k gaming monitors. The Samsung is higher-end with a faster 240Hz refresh rate, and it delivers better picture quality thanks to its Mini LED backlighting that helps it display deeper blacks. The Samsung also lets small highlights get brighter in HDR, so they pop more. The Samsung has a curved screen, while the ASUS has a flat screen with wider viewing angles, so it's the better choice for sharing your screen with others.

Samsung Odyssey Neo G7 S32BG75

The Samsung Odyssey Neo G7 S32BG75 and the ASUS ROG Swift PG27UQR are different types of 4k gaming monitors. The Samsung is bigger and delivers better picture quality thanks to its Mini LED backlighting, which helps display deeper blacks. The Samsung also lets small highlights get brighter in HDR, so they pop more. The Samsung has a curved screen, while the ASUS has a flat screen with wider viewing angles, so it's the better choice for sharing your screen with others.

Edge

The edge-lit local dimming feature has eight zones, and it performs terribly. This is because whenever there's a bright object against a dark background, an entire zone lights up, resulting in distracting blooming. It's also slow to react to objects moving across the screen, which is distracting. That said, really small highlights don't trigger any of the zones, so there isn't any blooming, but that's only with really certain content that features such small highlights. However, most content causes all the zones to turn on, meaning the local dimming feature isn't doing anything to improve the picture quality. At least you can enable and disable the Dynamic Dimming setting as you wish, but because it performs so terribly, it's better to disable it altogether.

The SDR brightness is great. It easily gets bright enough to fight glare and maintains the same brightness across different content, which is great. These results are from after calibration in the 'User Mode' GameVisual with the Brightness at its max and Dynamic Dimming disabled because it doesn't make the image brighter in SDR, and the local dimming feature performs terribly.

The ASUS PG27UQR has great HDR peak brightness. Most highlights get very bright, but because its local dimming feature doesn't turn on with really small highlights, they don't pop against the rest of the image. It also follows the PQ EOTF perfectly until there's a sharp roll-off at the peak brightness, allowing highlights to get the brightest they can. These results are with Dynamic Dimming enabled in the 'ASUS Gaming HDR' HDR mode. The only other HDR mode is 'ASUS Cinema HDR', which has a slower roll-off with the EOTF. It's tone mapping before your source does, but this is good for watching movies anyway as it preserves details.

The dedicated sRGB mode has excellent accuracy before calibration. Colors aren't oversaturated as most colors are accurate, and the white balance is also decent, but brighter shades of gray are a bit off. Gamma follows the sRGB curve almost perfectly, but the color temperature is on the cold side, giving the image a blue tint. Unfortunately, the sRGB mode locks a few settings, including Brightness, so you'll have to use another, less accurate mode if you want a brighter image, as you can see here.

The ASUS PG27UQR has an amazing response time at its max refresh rate of 160Hz. There's minimal motion blur, so fast-moving objects look smooth and buttery. You can choose from different Variable OD settings, with 'Level 2' and 'Level 3' performing the best, but 'Level 2' has just a bit less overshoot. The lower settings have a slower response time, while the higher settings have more overshoot.

The ASUS PG27UQR has an excellent response time at 60Hz. Like at higher refresh rates, the recommended 'Level 2' overdrive setting results in minimal blur, so it's a good set-and-forget mode with any game and refresh rate. It has a bit of overshoot, so if that bothers you, the 'Level 1' setting is a better choice.

The ASUS PG27UQR has an optional backlight strobing feature to reduce persistence blur. The ELMB setting is for when you want to use it with VRR disabled, and you have access to the Clarity Level and Clarity Position settings to control the pulse width and phase. It only works as low as 120Hz with VRR disabled, though. If you want to use it with VRR, you need to enable the ELMB SYNC setting, which also lets the feature continue working at lower refresh rates, but you don't have access to the Clarity Level and Clarity Position settings.

The ASUS PG27UQR has low input lag at high refresh rates, but it increases more than expected at 60Hz. We tested it multiple times, even with different equipment, and got the same results at 60Hz. While it isn't high enough to be noticeable while browsing the web or going through menus, it presents a competitive disadvantage when gaming. If you want something with a lower input lag at 60Hz, check out the LG 27GR93U-B.

macOS Compatibility

This monitor has some limitations with macOS, depending on your device and connection type. With a DisplayPort to USB-C cable, it supports VRR but not HDR, and the max refresh rate is 150Hz.

Over HDMI with the 2021 M1 MacBook Pro, which supports HDMI 2.0 bandwidth, the max refresh rate is 60Hz and HDR works, but not VRR. The 2023 M2 MacBook Pro supports HDMI 2.1 bandwidth, allowing you to reach a 144Hz refresh rate. However, while the system shows that it supports VRR, it doesn't actually work and results in a black screen.
