The LG 27GL83A-B is a very good monitor with a 27 inch, 1440p IPS screen. It delivers a great gaming experience with extremely low input lag, an outstanding response time, and a few great gaming features. It supports AMD's FreeSync variable refresh rate technology (VRR), but it's also certified by NVIDIA to support VRR from recent NVIDIA graphics cards. It has wide viewing angles, good reflection handling, and very good peak brightness, so glare shouldn't be an issue. As a more budget-oriented model, it has a pretty basic stand, with limited ergonomics and no RGB lighting. Although it supports HDR, this doesn't really add much, as it can't get bright enough to deliver a true HDR experience and has a low contrast ratio.

Our Verdict

7.6 Mixed Usage

The LG 27GL83A-B is a very good monitor for almost any use. It has remarkable motion handling and outstanding low input lag, which is great for gaming. It performs well in an office environment with its wide viewing angles and great peak brightness. Finally, its large size and high resolution make it a great choice for those who are looking for a monitor with good performance in media creation and multimedia.

Pros
  • Wide viewing angles.
  • Excellent gray uniformity.
  • Incredible response time.
  • Outstanding low input lag.
Cons
  • Low contrast ratio.
  • Limited ergonomics with no swivel.
7.7 Office

The LG 27GL83A-B is a good monitor for office use. The 27 inch, 1440p screen is great for multitasking. The viewing angles are excellent, so you don't have to worry about the sides of the screen fading if you sit too close. Unfortunately, it isn't the easiest monitor to place comfortably due to its disappointing ergonomics, but on the upside, you can place it in a bright office without issue due to its good reflection handling and very good peak brightness.

Pros
  • Good reflection handling.
  • Wide viewing angles.
  • Excellent gray uniformity.
Cons
  • Limited ergonomics with no swivel.
8.3 Gaming

The LG 27GL83A-B is a great monitor for gaming. It has an extremely low input lag and an outstanding response time, resulting in clear motion with little blur behind fast-moving objects. It supports FreeSync variable refresh rate technology (VRR), but it's also certified by NVIDIA to support VRR from recent NVIDIA cards. On the downside, it may be difficult to place it comfortably due to its lack of swivel and limited ergonomics.

Pros
  • Good reflection handling.
  • Incredible response time.
  • Outstanding low input lag.
  • Versatile variable refresh rate feature works with most graphics cards.
Cons
  • Low contrast ratio.
  • Limited ergonomics with no swivel.
7.2 Media Consumption

The LG 27GL83A-B is a good monitor for watching videos. It has a great resolution and size, delivering a more immersive movie-watching experience. The input lag is very low, and the monitor feels very responsive. The wide viewing angles are great for watching a movie together with a friend, although you might have a hard time positioning the monitor comfortably. It's not as good in a dark room, though, as it has low contrast and bad black uniformity.

Pros
  • Good reflection handling.
  • Wide viewing angles.
  • Excellent gray uniformity.
Cons
  • Low contrast ratio.
  • Limited ergonomics with no swivel.
7.7 Media Creation

The LG 27GL83A-B is a very good monitor for media creation. The high resolution and large size make it easier to see more of your project at once. Unfortunately, it might be difficult to position the monitor to your ideal position viewing position, but once you do, you should enjoy a very responsive experience thanks to the very low input lag. Also, the image remains accurate at the sides even when you sit up close to examine the details of your work.

Pros
  • Good reflection handling.
  • Wide viewing angles.
  • Excellent gray uniformity.
Cons
  • Low contrast ratio.
  • Limited ergonomics with no swivel.

Unfortunately, the LG 27GL83A-B has disappointing ergonomics, so it might be difficult to place it in an ideal viewing position. It has a decent height adjustment, but just an okay tilt range, and it can't swivel. The back of the monitor has a red circle like other UltraGear monitors. There's a quick release button and cable management is done through a clip in the stand.

The LG 27GL83A-B has an outstanding response time, similar to the LG 27GL850. Our recommended Response Time setting is 'Fast' as it delivers the best overall performance with the least amount of overshoot. There's a tiny bit of overshoot with the 'Fast' setting, but this isn't really noticeable. The 'Faster' setting has one of the fastest rise/fall times we've ever seen, with many transitions coming in under 1ms, but it also has significant overshoot, resulting in a long trail of inverse ghosting behind fast-moving objects. The replacement model, the LG 27GP83B-B has a higher maximum refresh rate, and a slightly faster response time.

The LG 27GL83A-B has an amazing response time at 60Hz, which is great for console gaming. Unlike at its max refresh rate, the recommended Response Time setting is 'Normal', so you might have to change your setting while gaming. This setting has less overshoot and motion blur than the 'Fast' setting, but both perform very similarly.

Unfortunately, there are some serious issues when using this monitor with recent Macs, including M1 MacBook Pros. It flickers constantly if VRR is disabled or if it's enabled and running at 144Hz. Disabling Adaptive Sync from the monitor's OSD also resolved the issue. In games, it flickers if the frame rate drops below about 75fps or if it's around 120fps. Setting a framerate cap to 120fps in MacOS fixes the flicker.

Differences Between Sizes And Variants

We tested the 27 inch 27GL83A-B, which is the only size available. It's been replaced in 2021 by the LG 27GP83B-B, which is very similar overall but has a higher refresh rate. 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 27GL83A-B doesn't correspond to our review, let us know and we'll update the review. Note that some tests, like gray uniformity, may vary between individual units.

Compared To Other Monitors

The LG 27GL83A-B is a great gaming monitor with remarkable motion handling. It has worse ergonomics than most comparable models, but if this isn't an issue, it's a great choice. See also our reviews for the best gaming monitors, the best 144Hz monitors, and the best 27 inch monitors.

Gigabyte M27Q

The Gigabyte M27Q and the LG 27GL83A-B are quite similar as they're both 27 inch IPS gaming monitors with a 1440p resolution. In terms of gaming performance, the main difference is that the Gigabyte has a higher refresh rate of 170Hz compared to the LG's 144Hz, but it has a slightly slower response time. The Gigabyte is better for content creation because it has a much better SDR and HDR color gamut, as well as better accuracy out of the box. It also has more features, like a Picture-in-Picture and Picture-by-Picture mode, and a USB-C port that supports DisplayPort Alt Mode. However, the LG has wider viewing angles if you need to share your screen often, and it can rotate to portrait mode, which the Gigabyte can't.

LG 27GN800-B

The LG 27GN800-B and the LG 27GL83A-B perform fairly similarly overall. However, the 27GN800-B has a slight edge if you can overlook the stand's terrible ergonomics. Both are 1440p 144Hz  monitors, but the 27GN800-B has a faster response time at both 60Hz and the max refresh rate. It also has a wider color gamut, and its better reflection handling makes it a little more suited to bright lighting conditions. 

LG 27GL850-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.

BenQ EX2780Q

The LG 27GL83A-B is marginally better than the BenQ EX2780Q in most uses. They're both very similar in terms of performance, but the LG has much better motion handling and it has a better HDR color gamut. Out-of-the-box color accuracy is also better on the LG, but its black uniformity is significantly worse than the BenQ.
