The LG UltraGear 27GL650F-B is a good 1080p, 144Hz IPS monitor with great gaming performance. It has an excellent response time resulting in clear motion, a black frame insertion feature to reduce motion blur, a low input lag, and a fast refresh rate. It delivers decent overall picture quality, with wide viewing angles, excellent gray uniformity, and great accuracy out of the box. Unfortunately, like most IPS monitors it doesn't look as good in a dark room, as it has a low contrast ratio and poor black uniformity. This monitor supports HDR, but this doesn't add much, as it can't get very bright in HDR and can't display a wide color gamut.

Our Verdict

7.7 Mixed Usage

The LG 27GL650F-B is good for most uses. It's a great gaming monitor thanks to its excellent response time, incredibly low input lag, and high refresh rate. Its large screen size is good for productivity, but the 1080p resolution might be too low for some to watch videos. Unfortunately, although it supports HDR, it can't display a wide color gamut. However, it has wide viewing angles if you want to share your screen with others.

Pros
  • Excellent response time.
  • Great peak brightness.
  • Great color accuracy out of the box.
Cons
  • Low contrast ratio and bad black uniformity.
  • Can't display wide color gamut for HDR.
7.7 Office

Good monitor for office use. The LG 27GL650F-B has wide viewing angles, great peak brightness, and decent reflection handling. The low native resolution might bother some people though, and it doesn't have a built-in USB hub. Luckily, it has great out-of-box color accuracy, so it doesn't need to be calibrated.

8.1 Gaming

The LG 27GL650F is a great monitor for gaming. It has an excellent response time, incredibly low input lag, and an excellent refresh rate with support for FreeSync variable refresh rate technology. Unfortunately, the low native resolution isn't ideal for some games, and it doesn't look as good in a dark room, as it has a low contrast ratio and poor black uniformity.

7.5 Multimedia

The LG 27GL650F-B is a good monitor for multimedia. It has excellent low input lag, wide viewing angles, and excellent gray uniformity. Unfortunately, it isn't great for watching movies in a dark room, and the low resolution isn't ideal if you want to watch higher quality videos.

7.6 Media Creation

Good monitor for media creation. The LG 27GL650F-B has great viewing angles, a fast response time, and excellent low input lag. It has an excellent SDR color gamut, but the Adobe RGB coverage might be too low for professional photo editing.

6.8 HDR Gaming

The LG 27GL650F-B is decent for HDR gaming, mainly due to its great gaming performance. It has outstanding low input lag and excellent response time, and it supports FreeSync for a nearly tear-free gaming experience. Unfortunately, HDR doesn't add much, as it can't display a wide color gamut, and can't get very bright in HDR.

The 27GL650F-B shares the same style as most other LG gaming monitors. It's mainly black with some red on the stand and on the back. There's a red circle on the back, but it's not illuminated like the 32GK850G.

Excellent response time at its max refresh rate. The recommended Overdrive setting is 'Faster' as motion looks very clear. There's still overshoot in some transitions, and if that bothers you, the 'Fast' setting has significantly less overshoot, but the response time is slower, so there's more motion blur.

The 27GL650F-B has a good response time at 60Hz, which is good news for console gamers. Unlike at 144Hz, the best Overdrive setting is 'Normal', so you might have to change your setting while gaming. This setting has the least amount of motion blur and minimal overshoot in most transitions.

Update 02/27/2020: We've clarified the text below, as G-SYNC Compatible mode only works over DisplayPort.

The LG 27GL650F-B has an excellent refresh rate, and it supports AMD's FreeSync variable refresh rate technology. It's also certified by NVIDIA as G-SYNC compatible, so it'll work with NVIDIA's adaptive sync drivers, as long as you have a recent NVIDIA graphics card, and only over DisplayPort. Certification for this monitor was added with NVIDIA Game Ready Driver version 436.30, so you might have to update your driver for it to work.

Compared to other monitors

The LG 27GL650F-B is a great budget gaming monitor. See also our reviews for the best gaming monitors, the best gaming monitors under $200, and the best gaming monitor sizes.

ASUS VG279Q
SEE PRICE
Amazon.com

The ASUS VG279Q is slightly better than the LG 27GL650F-B. The ASUS has much better ergonomics, with a 180° swivel range and a wider tilt range, so it's easier to place it in an ideal viewing position. Unlike the 27GL650F-B, the ASUS VG279Q doesn't support HDR, but this doesn't add much to the LG anyway.

LG 27GL850-B
SEE PRICE
Amazon.com

The LG 27GL850-B is slightly better than the 27GL650F-B. The 27GL850-B has a faster response time, resulting in clearer motion with less blur. The 27GL850 also has a better native resolution, so you can see more fine details in your favorite games, and it has an optional USB hub.

Acer Nitro VG271
SEE PRICE
Amazon.com

The LG 27GL650F-B is a bit better than the Acer Nitro VG271. Although they deliver similar performance overall, the LG has much better ergonomics, and it's officially certfied by NVIDIA as G-SYNC compatible, so FreeSync works automatically when connected to a recent NVIDIA graphics card.

MSI Optix G27C4
SEE PRICE
Amazon.com

The LG 27GL650F-B is much better than the MSI Optix G27C4. Although the 27GL650F-B doesn't have as high a refresh rate as the G27C4, its IPS panel has much better viewing angles, significantly better peak brightness, and better color accuracy. The 27GL650F-B also supports HDR and has better ergonomics, but its contrast ratio is much worse than the G27C4, and it has a slightly higher input lag.

Acer VG271UP
SEE PRICE
Amazon.com

The LG 27GL650F-B is a bit better than the Acer VG271UP. The LG has better ergonomics, and the unit we tested has better black uniformity. The Acer VG271UP has a higher native resolution though, so you can see more details in your favorite games.

ASUS TUF VG27VQ
SEE PRICE
Amazon.com

The LG 27GL650F-B is much better than the ASUS TUF VG27VQ. Although both have 27 inch 1080p screens, the LG has much better viewing angles for when you need to share your screen, it can get brighter, and it supports HDR content. However, gamers might prefer the higher refresh rate on the ASUS, and it has a better contrast ratio too, but the response time is much better on the LG, resulting in clearer motion handling.

Dell S2719DGF
SEE PRICE
Amazon.com

The LG 27GL650F-B is much better than the Dell S2719DGF for most uses, but the Dell is a bit better for gaming. The LG supports HDR, has better viewing angles, and an optional black frame insertion feature. The Dell has better ergonomics and a faster response time, and a higher native resolution.

Pixio PX7 Prime
SEE PRICE
Amazon.com

The Pixio PX7 Prime is slightly better than the LG 27GL650F-B. The Pixio has a faster refresh rate and a higher resolution display, as well as slightly better ergonomics. The LG has an optional black frame insertion feature, resulting in slightly clearer motion if you don't mind flicker.
