The ASUS TUF VG27AQ is an impressive 27 inch, 1440p monitor with excellent gaming performance. Thanks to its IPS panel, the image remains accurate at an angle, but blacks look gray in a dark room. It delivers a very responsive gaming experience thanks to its remarkably low input lag, and it has a very fast refresh rate that improves the overall appearance of motion. It also supports FreeSync variable refresh rate technology to reduce screen tearing. Unfortunately, even though it supports HDR, it doesn't display a wide color gamut for HDR content and can't get bright enough to bring out highlights.

Our Verdict

8.1 Mixed Usage

The ASUS TUF VG27AQ is a great monitor for most uses. This monitor has great resolution and size, a very low input lag, fantastic response time, wide viewing angles, and excellent ergonomics. It's a good choice if you often share your screen either for work or for a co-op gaming session. It's more suitable for an average-lit room as it can't get very bright and can't display deep blacks in a dark room.

Pros
  • Excellent ergonomics.
  • Fantastic response time.
  • Outstanding low input lag.
Cons
  • Can't display deep blacks in a dark room.
  • Lacks a wide color gamut.
8.0 Office

The ASUS TUF VG27AQ is a great monitor for office use. It has a great resolution and size that favors multitasking. You can easily share your work with a colleague thanks to the excellent ergonomics and the wide viewing angles ensure everyone viewing enjoys the same accurate image. It can get fairly bright to combat glare in most rooms, and thanks to the decent reflection handling, it performs well in most office environments.

8.5 Gaming

The ASUS TUF VG27AQ is an excellent monitor for gaming. The input lag is remarkably low and the high resolution and screen real estate allow you to see more details of your gaming arena. Fast-moving content has only minimal blur trail and the excellent refresh rate ensures smooth motion. Finally, the monitor's excellent ergonomics make it easy to position it comfortably on your desk.

7.9 Multimedia

The ASUS TUF VG27AQ is very good for consuming multimedia. The 1440p monitor can display most content at its native resolution, and thanks to the low input lag the monitor feels very responsive to your actions. It has decent reflection handling and wide viewing angles so you can enjoy a movie with a friend in a room that has a few lights without issue.

8.0 Media Creation

The ASUS TUF VG27AQ is a great monitor for creating media. The large size and great resolution allow you to see more of your work on the screen and the excellent ergonomics make it easy to place the monitor comfortably. The wide viewing angles allow you to collaborate with a colleague sitting next to you, while both enjoying the same accurate image. Finally, you can stay assured of a responsive editing experience due to the monitor's remarkably low input lag.

7.1 HDR Gaming

The ASUS TUF VG27AQ is a decent monitor for playing HDR games. Unfortunately, it has a mediocre contrast ratio, so blacks in a dark room look more like gray and there's no local dimming feature to improve this. It lacks a wide color gamut to properly display HDR content and it can't get bright enough to bring out highlights. On the upside, the input lag is outstanding and gaming experience feels very responsive.

The gamma doesn't follow the target curve closely and as a result, most scenes are darker. Since the color temperature is warmer than the target, the image has a slight red-yellowish tint.

Fantastic response time at its max refresh rate. The best Overdrive setting, which is called 'Trace Free', is '80'. It has the clearest motion out of all the settings, but there's overshoot in some brighter transitions. If that bothers you, the '60' setting performs very similarly, with a bit less overshoot.

The VG27AQ has an okay response time at 60Hz. The best Overdrive setting is '0' as there's no overshoot and there's no visible ghosting with fast-moving objects like the other settings. Since this is different than the setting at its max refresh rate, you might have to change it when playing games at 60Hz. If response time at 60Hz is important to you, then check out the ViewSonic Elite XG270QG.

Differences Between Sizes and Variants

We tested the 27 inch ASUS TUF VG27AQ, which is the only size available for this model. There are other TUF Gaming models available, some of which are listed below. We don't expect our review to be valid for the other models.

Some websites advertise the ASUS TUF VG27AQ with a 155Hz overclock instead of 165Hz. ASUS originally announced this model with a 155Hz overclock, but it was released with 155Hz, 160Hz, and 165Hz options. Some websites are still reporting the original information.

If someone comes across a different type of panel or if their VG27AQ doesn't correspond to our review, let us know and we will update the review. Note that some tests such as gray uniformity may vary between individual units.

The ASUS TUF VG27AQ is somewhat better than the LG 27GL850-B. The ASUS has a faster refresh rate that makes motion look smoother, and better ergonomics to help you place it comfortably on your desk. It supports a black frame insertion (BFI) feature that helps improve the overall appearance of motion and can also deliver more uniform blacks. The LG, on the other hand, has a faster response time, so fast-moving content has almost no blur, making the lack of BFI not an issue.

The ASUS TUF VG27AQ is much better than the Acer Predator XB271HU. The TUF supports HDR and has a faster refresh rate that improves the appearance of motion. The TUF supports FreeSync for nearly tear-free gaming, while the Predator supports G-SYNC for the same purpose. The TUF has better reflection handling, which is great for a room with a few more lights, and can also display more uniform blacks in a dark room. However, neither of the two monitors can display deep blacks in a dark room due to their IPS panels.
