The LG 27GL850 is acceptable for PC gaming. Although its 144Hz refresh rate isn't ideal for competitive gaming, it's still fine for entry-level gaming and has VRR support to reduce screen tearing. It has a decent response time at any refresh rate, as any motion blur isn't overly distracting, and it has low input lag for a responsive feel. That said, it has limited picture quality as it has a low contrast ratio and doesn't get bright enough for highlights to pop in HDR.
