The LG 27GN950-B is a fantastic 4K IPS monitor that has a low input lag, a low response time, and HDR support. But watch out for its poor native contrast ratio and terrible black levels.

Product Snapshot

Overview

The LG 27GN950-B is a high-end model released in December 2020. Unlike the older LG 27GL850, it features a 4K IPS display that promises to deliver better viewing angles and response time than VA monitors. In addition, LG assures seamless tear-free gaming with this monitor, as it supports all of the VRR methods like adaptive sync, NVIDIA G Sync, and AMD FreeSync Premium Pro. So, it is really well-positioned for PC gamers looking for a 4K monitor with an unrestricted budget. To learn more about reviewers’ opinions, continue reading our LG 27GN950-B review below.
