Hands-on review of the LG 27GL850 144Hz IPS monitor.
The LG 27GL850 is a great 1440p monitor. It has outstanding motion handling, with one of the fastest response times we've ever measured. This results in exceptionally clear motion in any scene, with almost no blur behind fast-moving objects. In this review, we compare it to the Gigabyte Aorus AD27QD, the ASUS ROG Swift PG279QZ, and the Dell S2719DGF.

It also has outstanding low input lag for a responsive gaming experience. This monitor supports AMD's FreeSync variable refresh rate (VRR) technology, but it's also NVIDIA certified as G-SYNC compatible, so VRR works automatically with a recent NVIDIA graphics card. Unfortunately, like almost all IPS monitors, it doesn't look as good in a dark room, as it has a disappointing contrast ratio and bad black uniformity.
