LG OLED B6 65" 4K Smart TV vs LG C5 55-Inch OLED TV

The C5 is the stronger TV: a brighter OLED evo panel, the Alpha 9 Gen8 processor, a 144Hz refresh rate and an anti-glare coating. The B6 is a step down in panel and processing, with the Alpha 8 chip and a 120Hz panel, but it keeps the same OLED strengths: perfect blacks, Dolby Vision, four HDMI 2.1 ports and full gaming support. The C5 also rates higher with owners, 4.4 from 142 ratings against 4.1 from 63. Buy the C5 unless the B6's larger 65-inch size matters more to you than brightness and motion.

  • Choose the LG B6 if you want a 65-inch OLED and the bigger screen matters more to you than peak brightness and the fastest motion handling.
  • Choose the LG C5 if you want the better picture: a brighter OLED evo panel, the Alpha 9 processor and a 144Hz refresh rate.

What reviewers say

LG OLED B6 65" 4K Smart TV

  • 4.1 / 563 ratings

Ratings average 4.1 out of 5 from 63 buyers. Owners tend to praise the picture and gaming features for the money, while some note the sound and brightness limits of an entry OLED.

What people mention
  • Picture qualityPraisedOwners say the OLED panel delivers deep blacks and strong contrast for the money.
  • Gaming featuresPraisedBuyers like the 120Hz panel, VRR and four HDMI 2.1 ports for consoles.
  • SoundCriticisedThe 20W 2.0-channel speakers are described as thin, with a soundbar recommended.
  • BrightnessMixedSome find it bright enough for dark rooms but dim in daylight.

LG C5 55-Inch OLED TV

  • 4.4 / 5142 ratings

Owners of LG's C-series generally praise the deep blacks, accurate colors and gaming features, and the C5 continues that reputation. Complaints tend to focus on brightness in bright rooms and on the set's built-in sound rather than the picture.

What people mention
  • Picture qualityPraisedOwners describe deep blacks, rich contrast and natural colors, especially in darker rooms.
  • GamingPraisedPlayers report low lag, smooth 120Hz and 144Hz motion and working VRR with current consoles.
  • BrightnessMixedIt looks excellent in dim rooms, but some owners find it dimmer than expected in a bright, sunlit room.
  • SoundCriticised

Questions and answers

Which is better for gaming?
The C5. Its 144Hz panel and Alpha 9 processor give it an edge, though both have four HDMI 2.1 ports, VRR, G-Sync and FreeSync Premium.
Is the C5 worth stepping up to over the B6?
Yes, if picture quality matters most. The OLED evo panel is brighter, the processor is a tier higher and the panel refreshes faster. The B6 only wins on screen size.
Which has the better picture?
The C5. OLED evo boosts brightness and the Alpha 9 Gen8 handles upscaling and contrast better than the B6's Alpha 8. Both still deliver true blacks and Dolby Vision.
Which lasts longer?
Neither is rated for a set lifespan. OLED panels can dim over many years, and LG covers both with the same panel warranty terms. The C5's anti-glare coating is the only durability difference.
Do both support Dolby Vision and Dolby Atmos?
Yes. Both list Dolby Vision and Dolby Atmos, and both run LG's webOS with LG Channels.
Should I pick the bigger screen or the better panel?
Pick the B6 if you sit far from the TV and want 65 inches. Pick the C5 if you sit closer and want the brighter, faster panel.
