The LG UltraGear 27GL850-B is a very good 1440p monitor. It has an outstanding response time, quicker than most 144Hz monitors we've seen so far. This results in exceptionally clear motion in any scene, with almost no blur behind fast-moving objects. It also has outstanding low input lag for a responsive gaming experience. This monitor supports AMD's FreeSync variable refresh rate (VRR) technology, and it's also NVIDIA certified as G-SYNC compatible, so VRR works automatically with recent NVIDIA graphics cards. Unfortunately, like almost all IPS monitors, it doesn't look as good in dark rooms, as it has a disappointing contrast ratio and poor black uniformity.

Our Verdict

7.8 Mixed Usage

The LG 27GL850-B is a very good monitor for pretty much any use. It's a great gaming monitor, with outstanding response time and extremely low input lag. It has wide viewing angles, good peak brightness, and good reflection handling, great for office use or watching videos with a few friends. It delivers a decent HDR gaming experience, but it's limited by its low native contrast and poor black uniformity.

Pros
  • Outstanding response time.
  • Wide viewing angles.
  • Excellent low input lag.
Cons
  • Disappointing contrast ratio and poor black uniformity.
  • Limited ergonomics.
7.8 Office

The LG 27GL850-B is a good monitor for office use. It has wide viewing angles, good peak brightness, and good reflection handling. It has a decent height and tilt adjustment, but it can't swivel, which might be an issue for some people. However, it has excellent gray uniformity, which is important for browsing the web or opening documents.

8.2 Gaming

The LG 27GL850-B is a great monitor for gaming. It has outstanding low input lag, a great resolution and size, and outstanding response time. It supports FreeSync, and is NVIDIA G-SYNC compatible, and it has a flicker-free backlight. Unfortunately, it has disappointing ergonomics, and it doesn't look as good in a dark room due to its low contrast ratio and poor black uniformity.

7.7 Multimedia

Overall, the LG 27GL850-B is a good monitor for multimedia. It has a great resolution and size, and wide viewing angles, so it's well-suited for sharing videos with your friends. Unfortunately, like most IPS monitors, it doesn't look quite as good in a dark room, as it has a disappointing contrast ratio and poor black uniformity.

7.8 Media Creation

Good monitor for media creation. The 27GL850-B has a great resolution and size, so you can see more of your work at once. It has great viewing angles, good peak brightness, and decent reflection handling. This monitor also has outstanding low input lag for a responsive desktop experience. Unfortunately, it doesn't look as good in a dark room, as it has poor black uniformity.

6.8 HDR Gaming

The 27GL850-B is decent for gaming in HDR, mainly due to the great gaming performance. It has a very low input lag and an outstanding response time, so fast-moving objects are extremely clear, with almost no blur behind them. It can display a wide color gamut in HDR, but unfortunately, it can't get bright enough to bring out highlights.

The 27GL850 has an outstanding response time at its max refresh rate of 144Hz. Our recommended Overdrive setting is 'Fast' as it has the least amount of motion blur, but there's still some overshoot in darker transitions. If that bothers you, the 'Normal' setting performs very similarly, but the response time is slower in all transitions, resulting in a bit more blur. If you want a similar gaming monitor with better response times, check out the Acer Nitro XV272U KVbmiiprzx or the LG 32GP850-B.

Compared To Other Monitors

Comparison picture

Left: Gigabyte Aorus AD27QD. Middle: LG 27GL850-B. Right: ASUS ROG Swift PG279QZ.

The LG 27GL850 is a great gaming monitor with outstanding motion handling. It has worse ergonomics than most comparable models, but if this doesn't matter for you it's a great choice. See also our reviews for the best gaming monitors, the best 1440p 144Hz monitors, and the best 27 inch monitors.

Dell S2721DGF

The Dell S2721DGF is a bit better overall than the LG 27GL850-B. The Dell has much better ergonomics, better build quality, and better reflection handling. On the other hand, the LG is more accurate out of the box, and for the two units we tested, the LG has better black uniformity, but this varies between units.

Gigabyte M27Q

The Gigabyte M27Q is a bit better than the LG 27GL850-B for most uses. Although they have similar response times, the Gigabyte has a higher refresh rate of 170Hz compared to the LG's 144Hz, resulting in a slightly smoother and more responsive gaming experience. Also, the Gigabyte's input lag is much lower at 60Hz than the LG's, making it more ideal for 60fps console gaming. For those in a well-lit room, the LG has better reflection handling, but it doesn't get as bright. The Gigabyte has more productivity features, including a USB-C port with DisplayPort Alt Mode support, an integrated KVM switch, and a Picture-in-Picture/Picture-by-Picture mode.

Samsung Odyssey G7 LC32G75T

The Samsung Odyssey G7 LC32G75T is a much better gaming monitor than the LG 27GL850-B. The Samsung has a VA panel that displays deep blacks, and it has better uniformity. It also has a 240Hz refresh rate, the response time is a bit quicker, and it's available in both a 27 and 32 inch size. However, the LG has an IPS panel with much better viewing angles.

Samsung Odyssey G5 LC27G55T

The LG 27GL850-B is much better than the Samsung Odyssey G5 LC27G55T for most uses. The LG has a much quicker response time to deliver smoother motion in fast-moving scenes. The LG uses an IPS panel that provides wider viewing angles, while the Samsung uses a VA panel that produces deeper blacks for a better dark room viewing experience. 

BenQ EX2780Q

The LG 27GL850-B is slightly better than the BenQ EX2780Q in mixed usage. Ergonomics are significantly better on the LG, as well as gradient performance. There's less color bleeding on the LG, but its black uniformity and contrast ratio are much worse than the BenQ.

ViewSonic Elite XG270QG

The LG 27GL850-B and the ViewSonic Elite XG270QG are two similar-performing monitors. The ViewSonic has a max refresh rate of 165Hz, G-SYNC support, a black frame insertion feature to help reduce motion blur, and better ergonomics. The LG supports HDR and has much better out-of-box color accuracy. Even though the LG has a max refresh rate of 144Hz, the two monitors still have a very similar response time, except the LG is quicker at 60Hz.

ASUS TUF Gaming VG27AQL1A

The ASUS TUF Gaming VG27AQL1A is better than the LG 27GL850-B. The ASUS has a 170Hz refresh rate, much better ergonomics, a BFI feature, and it gets brighter in HDR. However, the LG has a much quicker response time and better out-of-the-box color accuracy.

LG 27GL83A-B

The LG 27GL850-B and the LG 27GL83A-B have very similar overall performance and any differences can be attributed to panel variance. The 27GL850-B has better inputs as it incorporates two USB 3.0 ports, while the 27GL83A-B has no USB ports.

MSI Optix MAG274QRF-QD

The MSI Optix MAG274QRF-QD is a better gaming monitor than the LG 27GL850-B. They have similar features with a 1440p resolution, FreeSync support, G-SYNC compatibility, and a very quick response time. The MSI has a Black Frame Insertion feature, which the LG doesn't, but it has a narrow flicker range and can't be used with VRR enabled. The MSI also has much better ergonomics, including a swivel adjustment, which the LG doesn't have.

Gigabyte G27Q

The Gigabyte G27Q and LG 27GL850-B are two very good monitors, and they both have a 1440p resolution and 144Hz refresh rate. The Gigabyte gets brighter, so it does a better job at combatting glare and makes highlights stand out a bit more in HDR. On the other hand, the LG has a much quicker response time at 60Hz, so motion looks less blurry in 60fps games.

Lenovo Legion Y27q-20

Overall, the Lenovo Y27q-20 is a bit better than the LG 27GL850-B. The Lenovo has a slightly higher refresh rate, better ergonomics, and better color accuracy out of the box. However, the LG gets a little brighter in SDR and HDR, and it has better response time when running at 60Hz.

AOC CQ27G2

The LG 27GL850-B is much better than the AOC CQ27G2 for most uses. They use different panel technologies, each with their own strengths and weaknesses. The 27GL850-B has wider viewing angles, much faster response times, and higher peak brightness. The 27GL850-B supports HDR, but this doesn't add much. On the other hand, the AOC CQ27G2 has a much higher native contrast ratio, resulting in much deeper blacks.

ASUS ROG Strix XG279Q

The ASUS ROG Strix XG279Q is better than the LG 27GL850-B. The ASUS has much better ergonomics, it gets brighter, there's a BFI feature, and you can overclock its refresh rate to 170Hz. However, the LG has a lower input lag and it has wider viewing angles.

HP OMEN 27i

The LG 27GL850-B and the HP OMEN 27i perform very similarly, but the LG is slightly better overall. The LG supports HDR, although this doesn't add much. The LG has a slightly faster response time, but there's also more overshoot in our recommend 'Fast' overdrive setting. The LG is also more accurate out of the box. On the other hand, the HP is better-built, with excellent build quality.

Dell S2719DGF

The LG 27GL850-B is much better than the Dell S2719DGF for most uses, especially if ergonomics aren't important for you. The LG has much better picture quality, with wide viewing angles, much better gradient handling, and HDR support. The LG also has slightly better motion handling, with a slightly faster response time, resulting in slightly clearer motion.

Dell S3220DGF

The LG 27GL850-B and the Dell S3220DGF have very similar overall performance, with the LG being marginally better. The LG has an IPS panel with much wider viewing angles, it gets brighter, and it has better reflection handling.
