User Manual LG OLED55B7P B7 OLED 4K HDR Smart TV

Verdict. Overall, the 55-inch B7 is a terrific 4K TV. Offering vibrant, dynamic HDR images, it dazzles with the best of them, and has the ability to deliver profound black depth. It doesn't need UHD to look good either - the set does a great job with regular HD.

There are no major differences other than the design. The LG C7 and the B7P variant have a 2.2 speaker setup, which can internally decode Dolby Atmos sound. The B7A variant only has a 2.0 speaker setup and can't decode Dolby Atmos internally, although the C7 and all B7 models can output Atmos to an external receiver.
