The B6 is the better value pick for movies and everyday streaming, with Dolby Vision, Dolby Atmos, a strong α8 processor and a 4.7 out of 5 rating from 876 owners.

What reviewers say

LG OLED C5 Series 4K TV

  • BrightnessMixedReviewers say it is bright enough for most rooms but dimmer than the G5 and high-end Mini-LED sets.
  • GamingPraisedLow lag, 144Hz and VRR are called out as reasons to buy for consoles and PC.
  • Burn-inCriticisedSome owners worry about static logos and tickers during long news or sports viewing.

  • BrightnessPraisedAutomatic brightness adjustments are called convenient.

Questions and answers

Which is better for gaming?
The C5 has the higher 144Hz refresh rate, which suits fast shooters and racing games. The B6 still covers gaming well with VRR, G-Sync and FreeSync Premium at 120Hz.
Which has the better picture?
Both use OLED panels with near-infinite contrast, so blacks and viewing angles are close. The C5 steps up with a stronger α9 processor and an anti-glare coating for bright rooms.
Is the C5 worth stepping up to?
Yes if you game at high frame rates or watch in a sunny room. If you mostly stream movies, the B6 covers Dolby Vision and Atmos and is rated well by owners.
Which lasts longer?
Neither has a published lifespan advantage. Both are OLED sets, so burn-in risk depends on how you use them; vary content and avoid static logos for hours.
Does the B6 come in more sizes?
Yes. The B6 is listed in 48, 55, 65, 77 and 83 inches. The C5 is listed only at 55 inches here.
Do both support Dolby Vision?
Yes, both support Dolby Vision. The C5 also lists HLG and HDR10+, and the B6 adds Dolby Atmos sound processing.
