Which is better for a bright living room?

The C2's anti-reflective coating and higher brightness make it the easier watch in a sunny room, and its 77-inch size fills a large wall. The B6 is fine in a dimmer room or a smaller space.

Which is better for gaming?

The B6 edges ahead with VRR up to 144Hz and its newer processor. The C2 still offers 120Hz and four HDMI 2.1 ports, so both handle current consoles well.

Is the B6 worth stepping up to over the C2?

Only if you want the newest processing and 144Hz gaming and can accept a 65-inch screen. If screen size matters more, the C2 is the stronger choice.

Which has better sound without a soundbar?

The C2. Its 2.2-channel, 60W system is fuller than the B6's 20W 2.0 setup. Neither replaces a dedicated soundbar for serious movie watching.

Both are OLED sets with similar panel life. The B6 is newer, so it will likely receive webOS updates for longer, while the C2 is a 2022 model already further into its update cycle.

LG C2 77-Inch OLED evo TV vs LG B6 OLED evo 4K Smart TV

The LG C2 is the better pick for a large, bright living room or a serious movie and gaming setup: it is 77 inches, uses OLED evo panel tech with strong anti-reflective coating, and has four HDMI 2.1 ports with 120Hz support. The B6 is a newer 2026 65-inch set with the Alpha 8 Gen3 processor, Dolby Vision, and VRR up to 144Hz, so it suits gamers who want the latest processing and a smaller room. Owners consistently praise OLED blacks and wide viewing angles on both; the C2 gives you more screen and the B6 gives you newer internals.

Choose the LG C2 if you want the biggest OLED picture for a large room and mostly watch movies, sports and streaming.
Choose the LG B6 if you sit closer, game at high frame rates, and want the newest processor and Dolby Vision support.
