LG 55" B6 OLED AI 4K UHD Smart TV Black | OLED55B65LA
The LG OLED55B65LA B6 55" OLED AI 4K UHD Smart TV is a premium 2026 OLED television designed for customers who want deep black levels, excellent contrast, fast gaming performance and a more cinematic viewing experience. With its 55-inch 4K OLED display, it is ideal for living rooms, movie nights, sport, streaming and next-generation console gaming.
Unlike standard LED TVs, OLED uses self-lighting pixels that can switch on and off individually. This delivers Perfect Black, excellent contrast and rich colour without needing a backlight, helping movies, box sets and games look cleaner, deeper and more lifelike.
Powered by LG’s Alpha 8 AI Processor 4K Gen3, the B6 uses advanced AI picture and sound processing to sharpen detail, enhance colour and optimise everyday viewing. Alpha 8 AI Super Upscaling 4K helps improve lower-resolution content, while AI Picture Pro, AI HDR Remastering, Dynamic Tone Mapping Pro, Dolby Vision, HDR10, HLG and Filmmaker Mode help compatible movies and shows look more detailed and cinematic.
The webOS 26 smart platform gives easy access to streaming apps, LG Channels, Google Cast, Apple AirPlay, Apple Home and LG ThinQ smart features. It also includes LG Shield, helping protect the smart TV experience with ongoing security support.
For gaming, the LG B6 is a major step up from standard 60Hz TVs. It supports 4K 120Hz, VRR up to 120Hz, NVIDIA G-SYNC compatibility, AMD FreeSync Premium, ALLM, HGiG, Dolby Vision Gaming at 4K 120Hz and a response time of under 0.1ms, making it a strong option for PlayStation, Xbox and PC gaming.
This model includes 4 HDMI inputs, with support for 4K 120Hz, eARC, VRR, ALLM, QMS and QFT, plus USB, Wi-Fi 5, Bluetooth 5.3, Ethernet and optical audio out. The AI Magic Remote MR26GA / MR26GB with number keys is included for point, scroll and voice control.
With 20W 2.0 channel sound, Dolby Atmos, Alpha 8 AI Sound Pro Virtual 11.1.2 Up-mix, Clear Voice Pro and WOW Orchestra support, the LG OLED55B65LA is a premium 55-inch OLED TV for movies, sport, gaming and everyday entertainment.
