Overview
Not an LED-backlit set, this LG is an OLED whose pixels light themselves for true blacks and rich contrast. An AI processor tunes picture and sound to the content, and Multi View splits the screen in two.
OLED contrast plus gaming features like VRR, G-Sync and four full-speed HDMI inputs make it a strong all-rounder. Built-in sound is the weak spot, with a simple two-channel setup.
Who it's for
Console gaming, movie nights and sports in a living room or bedroom suit a mid-size OLED. People who need loud, full audio without extra gear should budget for a soundbar.
Pros and cons
- Self-lit OLED contrast
- Four HDMI 2.1 inputs
- Very fast response
- G-Sync and FreeSync
- Short parts and labor warranty
- Glare in very bright rooms
Performance notes
Self-lit pixels switch off completely, which gives true blacks and crisp highlights side by side. A native fast refresh and near-immediate pixel response keep motion sharp in games and sports.
