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

7.6 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.
7.7 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.

7.2 Media Consumption

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.

7.7 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.

This monitor has disappointing ergonomics. It has a decent height adjustment and it can rotate to portrait orientation, but its tilt range is limited and it can't swivel.

The back of the monitor is very similar to other UltraGear monitors. There's a quick-release on the stand, but only very basic cable management through a clip attached to the stand.

Unfortunately, the 27GL850 has mediocre HDR peak brightness. It can't get bright enough to show off small, bright highlights in HDR content.

Note: While trying to measure the HDR real scene peak brightness, we encountered a bug, and the monitor started to flicker. We don't know why this happened, and we didn't encounter it with our other HDR tests.

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.

Incredible response time at 60Hz, better than most 144Hz monitors, which is great news for console gamers. Unlike the Overdrive setting at its max refresh rate, the recommended setting is 'Normal'. It has significantly less overshoot than the 'Fast' and 'Faster' settings and motion looks the clearest.

Unfortunately, this monitor doesn't work well with recent MacBooks. HDR doesn't work properly, as the monitor doesn't tone map properly, so it looks terrible overall. The variable refresh rate feature is completely unusable, and even the max refresh rate of 144Hz doesn't work properly with a fixed refresh rate. It works okay at 120Hz in SDR, with no major issues in that mode. Windows return to their original positions after the computer wakes from sleep, but not if you just close the lid.

There are very few additional features on this monitor. Like other UltraGear monitors, it can display a virtual crosshair on any game. There's also a 'Black Stabilizer' feature, which adjusts the gamma in dark scenes, making it easier to spot objects in the shadows.

If you want a monitor with more extra features, take a look at the Gigabyte Aorus FI27Q.

Differences Between Sizes And Variants

We tested the 27 inch 27GL850-B, which is the only size available. There are other models in LG's UltraGear lineup, some of which are listed in the table below.

If someone comes across a different type of panel or if their 27GL850 doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.

Compared To Other Monitors

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.

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.

LG 27GN800-B

The LG 27GL850-B and the LG 27GN800-B perform quite similarly overall. While the 27GN800-B has a slightly faster response time, it also has a terrible stand with very few adjustment options. That may not be a problem if you plan on VESA-mounting it, however. The 27GL850-B, on the other hand, includes two USB 3.0 ports, offering more connectivity than the 27GN800-B, if that's important to you. 

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.

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.

LG 27GP850-B

The LG 27GP850-B is better than the LG 27GL850-B, but the differences are minor and might not matter to everyone. The 27GP850-B has a slightly faster refresh rate, resulting in better motion handling and a touch less motion blur behind fast-moving objects. The 27GP850-B also has an optional black frame insertion feature, but most people won't use this when gaming anyway.

ASUS TUF VG27AQ

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.

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.

Acer Predator XB271HU Bmiprz

The LG 27GL850-B is better than the Acer Predator XB271HU Bmiprz. The LG supports HDR and can handle reflections better, which is important when there are a few lights in your room. The Acer, on the other hand, has a black frame insertion feature that helps make the image look crisper.

ASUS ROG Swift PG279Q

The ASUS ROG Swift PG279Q and the LG 27GL850-B have very similar overall performance, but they have some significant differences.
