The LG 27GL83A-B is a good 1440p IPS monitor with great gaming performance. It has an outstanding response time that delivers fast-moving content with almost no blur trail, and an outstanding low input lag for very responsive gaming sessions. Also, this monitor supports FreeSync variable refresh rate technology and is G-SYNC compatible, offering a nearly tear-free gaming experience. Unfortunately, this monitor can't display deep blacks in a dark room due to the low contrast ratio, so it's not a good choice for late-night gaming. However, it can get fairly bright, suitable for most rooms, and supports HDR, although it can't get very bright in that mode.

Our Verdict

7.8 Mixed Usage

The LG 27GL83A-B is a 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 resolution and size make it a great choice for those who are looking for a monitor with good performance in media creation and multimedia.

Pros
  • Outstanding response time.
  • Excellent low input lag.
  • Good out-of-the-box accuracy.
Cons
  • Disappointing contrast ratio and poor black uniformity.
7.8 Office

The LG 27GL83A-B is a good monitor for office use. It has a high resolution and size that favors multitasking. The viewing angles are excellent, and this is good news if you often share your work with a colleague. Unfortunately, it isn't the easiest monitor to place comfortably due to its disappointing ergonomics, but on the upside, you can place it a bright office without issue due to its good reflection handling.

8.2 Gaming

The LG 27GL83A-B is a great monitor for gaming. It has an extremely low input lag and an outstanding response time that delivers a crisp image regardless if it's displaying fast-moving content or not. It supports FreeSync for nearly tear-free gaming, but on the downside, it may be difficult to place it comfortably due to its lack of swiveling.

7.7 Multimedia

The LG 27GL83A-B is a good monitor for consuming multimedia. It has great resolution and size and displays most content at its native resolution. The input lag is very low and the monitor feels very responsive. The wide viewing angles favor watching a movie together with a friend, although you might have a hard time positioning the monitor comfortably.

7.8 Media Creation

Very good monitor for media creation. The high resolution and large size on the LG 27GL83A-B allow you to watch more of your project on your screen. Unfortunately, it'll take you a little longer to position the monitor to your ideal 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.

6.9 HDR Gaming

The LG 27GL83A-B is a decent monitor for gaming in HDR, mainly due to the great gaming performance. The low contrast ratio prevents it from displaying deep blacks in a dark room where HDR is meant to be watched. On the upside, it displays a wide color gamut in HDR, but its brightness is just decent and can't deliver highlights as it should.

  1. Update 8/31/2020: We rechecked our color gamut results, as they seemed strange, but we arrived at the same results as before.
  2. Update 6/4/2020: We retested FreeSync over HDMI, and updated our results below.
  3. Update 2/17/2020: Converted to Test Bench 1.1.

The 27GL83A-B looks like every other monitor in LG's UltraGear lineup. It's mainly black with a red circle on the back and the stand has wide-set feet. It's designed as a gaming monitor, but fits nicely into any office environment.

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.

Good out-of-the-box color accuracy. Most colors are fairly accurate and the color temperature is extremely close to the 6500K target. Unfortunately, the gamma curve doesn't follow the target curve well, so dark scenes are darker than they should, and bright scenes are brighter.

The 27GL83A-B has excellent post-calibration color accuracy. Any remaining errors can only be observed with the aid of a colorimeter and aren't noticeable in normal content. Gamma follows the target curve almost perfectly, and the color temperature is almost spot on the 6500K target.

Outstanding response time, similar to the 27GL850. The recommended Overdrive setting is 'Fast' as motion looks very clear on it. There's some overshoot in darker transitions, and if that bothers you, the 'Normal' setting has a lot less overshoot, but there's more motion blur.

The 27GL83A-B has an amazing response time at 60Hz, which is great for console gaming. Unlike at its max refresh rate, the recommended Overdrive 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.
