Product Snapshot

Overview

The LG OLED GX is the brand’s top tier OLED TV released in 2020. It claims its impressive color accuracy, infinite contrast ratio, and color-popping scenes are the work of its a9 Gen 3 AI 4K processor for a completely immersive viewing experience and OLED pixels that can brighten, shut off completely, or somewhere in between.

It also boasts a 120Hz refresh rate, making games smoother than ever. Read our LG OLED GX review to find out what experts have to say, then check out top-rated TVs available today.

Consensus

our Verdict

The LG OLED GX is a top-tier option for the entire range of entertainment. Its near-infinite contrast ratio and beautiful picture quality make it fantastic for movies and games—especially in the dark.

Gamers will love its 120Hz refresh rate, near-instantaneous response time, and low input lag.

It lacks HDR10+, however, and the stand is sold separately. Furthermore, there’s the risk of burn-in.

ReasonS to Buy

  • Virtually infinite contrast ratio
  • Response time is nearly instant
  • Supports VRR (Variable Refresh Rate)
  • Beautiful picture quality
  • Accurate upscaling performance
  • Has a NextGen TV ATSC 3.0 tuner

Reason to Avoid

  • No HDR10+
  • Inconsistent ABL (Automatic Brightness Limiter)
  • Risk permanent burn-in.
  • Glass surface is slightly reflective
  • Stand sold separately
