Product Snapshot


Intro: The LG 34GP83A-B is a mid-tier ultrawide gaming monitor that was announced in 2020, with a pledge to deliver an immersive gaming experience. The monitor’s 160Hz variable refresh rate is ideal for gaming compared to the LG 34WN80C-B’s 60Hz. It is also G Sync compatible and FreeSync supportive, making it a great pick for users who want to enjoy fast-paced game-play without any screen tearing. In addition, a super-fast 1ms response time reduces motion blur to the absolute minimum, and this allows for super smooth transitions, especially during fast-action scenes. Read through the rest of this LG 34GP83A-B review to find out what else lies in store, and how it compares to the best-rated computer monitors in the market.


our Verdict

The LG 34GP83A-B is a great choice for gamers, with its low input lag, quick response time, Variable Refresh Rate support, decent viewing angles, and high color accuracy. However, its low peak HDR brightness, poor black levels, and unergonomic stand may be a dealbreaker. The stand doesn’t allow for swiveling or pivoting, and its HDR brightness isn’t bright enough for a true cinematic experience.
