The LG OLED55B6 is a 55-inch 4K OLED smart TV from LG's 2026 OLED lineup, in the B6 series. It's built around the alpha8 AI Processor 4K Gen3, delivering UL-verified Perfect Black and Perfect Colour with sharper 4K detail.
AI Picture Pro combines AI Super Upscaling and Dynamic Tone Mapping Pro to refine every frame to 4K with balanced brightness and detail, while AI HDR Remastering elevates SDR content to HDR-level colour, brightness, and contrast. Perfect Black holds its depth and clarity in both bright and dark rooms, and the screen is Eyesafe-verified for certified reduced blue light.
The webOS platform is a CES 2026 Innovation Award honoree for both its Multi-AI Architecture and LG Shield-secured TV OS. Full AI Hub functionality, including Multi AI Search, AI Concierge, AI Voice ID with My Page, an AI Chatbot, and Far Field Voice Recognition, becomes available once paired with the AI Magic Remote, which is sold separately on this model. The TV has been named Best Smart TV System 2025/26 by AVForums for 8 years running.
AI Object Remastering Pro automatically clarifies voices and key sounds amid background noise, and Virtual 11.1.2 Ch AI Sound creates multi-dimensional, room-filling audio. Dolby Vision with Ambient FILMMAKER MODE and Dolby Atmos deliver cinema-accurate picture and 360-degree immersive sound, and WOW Orchestra syncs with an LG soundbar for fuller surround sound.
Gaming features include up to 120Hz VRR in 4K with NVIDIA G-Sync and AMD FreeSync Premium compatibility plus HGiG mode, and 0.1ms response time with ALLM for near-instant input response. NVIDIA GeForce NOW brings 4K 120Hz HDR cloud gaming with no extra device needed, and Bluetooth Ultra Low Latency Controller support keeps cloud gaming input delay under 2.5ms.
The ultra-slim design has narrow bezels, four HDMI ports supporting 4K 120Hz, eARC, VRR, ALLM, QMS, and QFT, one USB 2.0 port, Wi-Fi 5, Bluetooth v5.3, and Ethernet.
