LG OLED evo AI C6 4K TV vs LG B6 OLED evo 4K Smart TV

It has the brighter evo panel, the faster a11 Gen3 processor, four full HDMI 2.1 ports with up to 165Hz and both G-Sync and FreeSync, and a stronger 2.1-channel sound setup. The B6 keeps the same OLED contrast and Dolby Vision but runs a slower Alpha 8 processor, a 120Hz native panel and 20W 2.0 audio.

  • Choose the LG B6 if you mainly stream movies and shows in a dim room and want OLED contrast without paying for gaming extras.

What reviewers say

LG OLED evo AI C6 4K TV

  • 4.8 / 5166 ratings

Rated 4.8 out of 5 from 166 ratings, the C6 is received as a strong all-round OLED. Owners single out picture quality and gaming features; brightness in bright rooms is the recurring caveat.

What people mention
  • Picture qualityPraisedOwners describe deep blacks and vivid color as the main reason to buy.
  • GamingPraisedHigh refresh and VRR over HDMI 2.1 are called out as a big plus.
  • BrightnessMixedFine in dim rooms, but some find it dimmer than expected in daylight.
  • GlareCriticisedReflections show on the glossy screen in bright rooms.

Questions and answers

Which is better for gaming, the C6 or the B6?
The C6. It runs up to 165Hz, supports both G-Sync and FreeSync Premium, and has four HDMI 2.1 ports. The B6 tops out at 120Hz native with 144Hz VRR and lists no G-Sync or FreeSync.
Is the C6 worth stepping up to over the B6?
Yes if you watch in a bright room or game on a PC or current console. The evo panel, Alpha 11 processor and full HDMI 2.1 set are real upgrades. If you mostly stream in a dim room, the B6 covers the basics.
Do both have Dolby Vision and Dolby Atmos?
Both support Dolby Vision HDR. Only the C6 lists Dolby Atmos; the B6 has a 20W 2.0 speaker system, so plan on a soundbar for either.
Which lasts longer?
Both are OLED sets with similar panel life. The C6's brighter panel and faster processor keep it feeling current longer, while the B6's simpler hardware has fewer features to age.
Which is better in a bright room?
The C6. Its OLED evo panel with Brightness Booster pushes more light than the standard OLED panel in the B6, so reflections and daylight wash out the picture less.
Do they run the same smart TV software?
Both use LG's webOS. The C6 ships on webOS 26 with Alexa, Google Assistant, Siri and HomeKit; the B6 lists Google Assistant and Siri support.
