LG C5 OLED TV vs LG OLED B6 Series 65-Inch TV

The LG C5 is the stronger TV of the two. Its α9 Gen8 processor, Brightness Booster panel, four HDMI 2.1 ports and 144Hz VRR give it more headroom for HDR and PC gaming than the B6, whose a8 Gen3 chip and 120Hz panel sit a step below. Owners praise the C5's crisp, bright picture and built-in sound, though some report buggy early software, forced ads and a non-swivel stand. The B6 is the sensible pick if you want true OLED blacks and full gaming features without paying for the C5's extra brightness and processing.

  • Choose the LG C5 if you want the brightest picture, the best processing and 144Hz gaming from LG's OLED line.
  • Choose the LG OLED B6 if you want self-lit OLED contrast, Dolby Vision and full HDMI 2.1 gaming at the lower tier of LG's range.

What reviewers say

LG C5 OLED TV

  • 4.8 / 518,000 ratings

With 4.8 out of 5 from about 18,000 ratings, owners are largely enthusiastic about the C5's picture and gaming features. They praise crisp, vivid images with deep blacks, even pixels and easy setup. The main complaints are value for money, banding in dark scenes and the fixed stand.

What people mention
  • Picture qualityPraisedOwners praise the crisp, vivid picture, rich color and perfect blacks, especially for dark-room movies.
  • BrightnessMixedMany say the high brightness makes the picture pop, but some find it less bright or colorful than competing OLEDs in well-lit rooms.
  • GamingPraisedGamers like the 144Hz VRR, low response time and four HDMI 2.1 ports.
  • ReflectionsMixedThe anti-glare coating helps, but owners still notice reflections in daylight.

LG OLED B6 Series 65-Inch TV

Owners of LG's B-series OLEDs praise the picture in dark rooms and the gaming features for the price. The recurring complaint is brightness in daylight and reflections on the glossy screen.

What people mention
  • Picture qualityPraisedOwners say the OLED panel delivers deep blacks and strong contrast, especially in dim rooms.
  • BrightnessCriticisedReviewers note the B series is dimmer than LG's C and G models and struggles in bright rooms.
  • GamingPraisedFour HDMI 2.1 ports at 4K 120Hz and low lag are called out as strong for the price.
  • ReflectionsCriticisedThe glossy screen shows reflections from windows and lamps.

Questions and answers

Which is better for gaming, the C5 or the B6?
Both have four HDMI 2.1 ports, VRR, G-Sync, FreeSync Premium and 0.1ms response. The C5 adds a 144Hz mode for PC gaming, so it edges ahead if you play on a high-refresh PC.
Is the C5 worth stepping up to over the B6?
Yes if brightness and processing matter to you. The C5's Brightness Booster and α9 Gen8 chip handle HDR and upscaling better, and it adds Wi-Fi 6E. The B6 keeps the same OLED contrast and gaming features for less.
Which has the better picture in a bright room?
The C5. Its Brightness Booster raises peak brightness, and reviewers call it impressively bright. The B6 uses a standard OLED panel and is dimmer in daylight.
Which lasts longer?
Neither has a clear edge on hardware life. The C5 ships with webOS 25 and LG's Re:New program promises up to five years of updates, which keeps it current longer on software.
Do either need a soundbar?
C5 owners often say the built-in sound is enough. The B6 has a 40W 4.0-channel system with Dolby Atmos; a soundbar helps both for serious movie watching.
Which is better for movies?
Both support Dolby Vision, Dolby Atmos and Filmmaker Mode. The C5's brighter panel and better processing give it the edge on HDR highlights and upscaled content.
