  • Excellent low input lag.
  • Ergonomic design


  • Low contrast ratio

Picture Quality

The picture quality of the LG 27GL83A-B is good. The monitor has a wide color gamut, can display vibrant HDR colors, and can be bright enough for most games in HDR.

As expected for an IPS monitor the LG 27GL83A-B has a low native contrast ratio. Sadly, blacks would look more like gray in a dark room.

The LG 27GL83A-B has good horizontal viewing angles, like most IPS monitors For reasonably large angles, the image remains accurate.


The LG 2783A is a very good monitor for virtually any use It has amazing motion and outstanding low input latency, which is perfect for gaming.

It has wide viewing angles and high peak brightness.

Design & Connectivity

The design of the LG 27GL83A-B is good with decent height and tilt adjustment, but it can’t swivel.
