  • Slim design that mounts close to the wall
Cons

Questions and answers

Which is better for gaming?
The C6. It has four HDMI 2.1 ports, VRR up to 165Hz, a 0.1ms response time and FreeSync Premium. The B5 does 120Hz with G-Sync and FreeSync, but its HDMI version is not stated.
Is the C6 worth $500 more than the B5?
Yes if you watch in a bright room or game seriously. The evo panel, Alpha 11 Gen3 chip and HDMI 2.1 ports are real upgrades. If you watch in a dark room and want the biggest screen, the B5 saves money.
Which has the bigger screen?
The B5 listing is 77 inches wide across, against 65 inches for the C6. Check the exact model you order, because both series come in several sizes.
Which is brighter?
The C6. OLED evo with Brightness Booster is LG's brighter panel, and the Alpha 11 Gen3 processor adds better tone mapping. The B5 uses a standard OLED panel.
Do both support Dolby Vision and Dolby Atmos?
Yes. Both list Dolby Vision, Dolby Atmos and FILMMAKER MODE, and both run webOS with Netflix, Prime Video, Disney+ and YouTube.
Which lasts longer?
Neither maker publishes an hours rating, so there is no clear winner. OLED pixels dim over time on both, and the C6's brighter panel runs harder at peak brightness.
