LG OLED C6 65-inch TV vs LG B5 Series 65" OLED TV

The LG C6 is the stronger TV of the two. It has a brighter evo panel with Brightness Booster, the faster a11 Gen3 processor, a 2.2-channel speaker system with Dolby Atmos, and a newer webOS with AI assistants. The B5 uses a standard OLED panel and the Alpha 8 Gen2 chip, so it is dimmer in bright rooms and has weaker built-in sound. Both are 65-inch 4K OLEDs at 120Hz with Dolby Vision, four HDMI ports and VRR, so the B5 still delivers perfect blacks and wide viewing angles. Owners rate the C6 higher, and the B5 is the sensible pick only when the C6's extra brightness and processing are not worth the step up to you.

  • Choose the LG OLED C6 if you watch in a bright room, want the brightest OLED picture LG makes at this size, and care about stronger built-in sound and faster processing.
  • Choose the LG OLED B5 if you mainly watch in a dark room and want core OLED picture quality, Dolby Vision and 120Hz gaming without paying for the brighter panel.

Questions and answers

Which is better for a bright living room?
The C6. Its evo panel with Brightness Booster holds up better against daylight and reflections. The B5 is dimmer and looks its best in a darker room.
Is the C6 worth stepping up to over the B5?
Yes if you want more brightness, faster processing and better built-in sound. If you watch mostly at night and use a soundbar, the B5 covers the basics well.
Which is better for gaming?
Both are 120Hz OLEDs with VRR. The C6 adds FreeSync Premium and a faster processor, so it edges ahead, but the B5 handles consoles well with G-Sync and ALLM.
Do both support Dolby Vision and Dolby Atmos?
Yes. Both handle Dolby Vision, HDR10 and HLG, and both decode Dolby Atmos. The C6 has the better speaker array to make use of Atmos.
Which lasts longer?
Both use OLED panels with similar lifespans, and the C6 adds OLED Care to protect the display. Neither has a meaningful durability edge in normal use.
Do both have the same ports?
Both have four HDMI inputs. The C6 adds two USB ports, Ethernet and optical audio, while the B5 lists eARC for soundbars.
