Overview
LG puts its self lit OLED panel and alpha eight AI processor into the B series, a big screen for films, sports and gaming. Four HDMI inputs with variable refresh support suit consoles and PCs, and webOS brings streaming apps and casting.
OLED contrast and gaming features make it a strong all rounder for dark room movies and consoles. The speakers are basic two channel, so a soundbar lifts the experience.
Who it's for
Families watching films and console gamers get deep contrast and smooth motion. Those who rely on TV speakers for movie nights will want to add audio.
Pros and cons
- Self lit OLED contrast
- Fast response time
- Four HDMI 2.1 inputs

Performance notes
Each pixel makes its own light, so dark scenes stay black without glow, and dynamic tone mapping adjusts HDR frame by frame. Gaming smoothness depends on a variable refresh source feeding the HDMI inputs.
