Our Verdict
LG C7 OLED
LG B7/B7A OLED
The performance of the LG B7A and LG C7 is nearly identical. 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.
