Our take on the 77" Class B6 Series OLED AI 4K Smart TV

The LG B6 is a 77-inch OLED TV with self-lit pixels for perfect black and wide viewing angles, plus a native 120Hz panel with a 0.1ms response time. It supports Dolby Vision, Dolby Atmos, FILMMAKER MODE and gaming features including G-Sync, FreeSync Premium and VRR. It suits movie and sports viewers who want deep contrast in a bright room and gamers who want a large, fast screen. Against LG's brighter C and G evo models it gives up some peak brightness and processing, but keeps the core OLED strengths at a lower tier of the lineup.

Questions and answers

Is the LG B6 good for gaming?
Yes. It has a native 120Hz panel, a 0.1ms response time and support for G-Sync, FreeSync Premium and VRR, plus a Game Optimizer menu.
How does the B6 compare with LG's C series?
The C series uses brighter evo panels and stronger processing. The B6 keeps OLED contrast and gaming features but gives up some peak brightness.
Does it support Dolby Vision and Dolby Atmos?
Yes. Both are supported, along with FILMMAKER MODE for director-intended picture settings.
Should I worry about burn-in?
OLED panels can retain static images over long periods. Vary content and avoid leaving news tickers or game HUDs on for hours.
