LG OLED B6 65" 4K Smart TV vs LG C6 Series OLED 4K Smart TV

The LG C6 is the stronger TV: its Alpha 11 processor, Brightness Booster Pro panel and 165Hz refresh put it a clear step above the B6's Alpha 8 chip and standard OLED brightness. The B6 is still a true OLED with 120Hz, four HDMI 2.1 ports and Dolby Vision, so it covers gaming and streaming well. Buy the C6 if you watch in a bright room or want the best picture LG makes at this size; buy the B6 if you want OLED blacks and 120Hz gaming and can accept dimmer highlights and a smaller 65-inch panel versus the C6's 55-inch listing here.

  • Choose the LG B6 if you want a 65-inch OLED with 120Hz, four HDMI 2.1 ports and Dolby Vision, and you mostly watch in a dim or controlled room.
  • Choose the LG C6 if you want LG's brightest OLED panel, the faster Alpha 11 processor and 165Hz motion, and a 55-inch size fits your room.

What people mention

Questions and answers

Which is better for a bright living room?
The C6. Its OLED evo panel with Brightness Booster Pro is rated up to 3.2x brighter than a standard OLED, so it holds up better against window light. The B6 is better suited to a dim or controlled room.
Is the C6 worth stepping up to over the B6?
Yes for picture quality. The Alpha 11 chip, brighter panel, 165Hz refresh and webOS 26 are real upgrades. Step down to the B6 only if you need the larger 65-inch screen or want to spend less.
Which is better for gaming?
Both have four HDMI 2.1 ports, VRR and 120Hz 4K gaming. The C6 adds a 165Hz panel and the faster processor, so it edges ahead. The B6 still covers consoles and cloud gaming well.
Which lasts longer?
Both use LG OLED panels with similar lifespans. The C6 adds OLED Care, which helps protect the panel over time. Neither has a meaningful durability advantage otherwise.
Do both support Dolby Vision and Dolby Atmos?
Both support Dolby Vision, HDR10 and HLG. The C6 lists Dolby Atmos; the B6's built-in audio is a 20W 2.0 channel setup, so a soundbar helps either way.
Which has the better smart TV system?
The C6 runs webOS 26, one generation newer than the B6's webOS 24. Both cover Netflix, Prime Video, YouTube and Disney+, but the C6 gets the newer interface and features.
