LG OLED evo C4 55-inch TV vs LG B6 OLED evo 4K Smart TV

The LG C4 is the stronger TV. It uses LG's brighter evo OLED panel with the Alpha 9 Gen7 processor, and it is the set reviewers and owners consistently praise for picture quality and gaming. The B6 is a larger 65-inch OLED with the same 120Hz panel and 144Hz VRR, but it runs the lower-tier Alpha 8 Gen3 chip and a dimmer panel, so it trades some punch for screen size. Buy the C4 for the best picture at 55 inches; buy the B6 if a bigger screen matters more than peak brightness and processing.

  • Choose the LG C4 if you want the best picture quality, the brightest OLED panel and the top processor in this size class.
  • Choose the LG B6 if you want a 65-inch OLED and a larger screen matters more to you than peak brightness and the step-up processor.

What reviewers say

LG OLED evo C4 55-inch TV

  • 4.7 / 5493 ratings

Rated 4.7 out of 5 from 493 ratings, the C4 is well liked for its picture and gaming features. Owners treat it as a strong all-round home theater set rather than a budget pick.

What people mention
  • Picture qualityPraisedOwners single out the deep blacks and contrast as the reason to buy OLED.
  • GamingPraisedLow response time, VRR and four HDMI 2.1 ports get frequent praise from console players.
  • BrightnessMixedFine in dim rooms, but some find it dimmer than expected in daylight.
  • ReflectionsCriticisedThe glossy screen with no anti-glare coating shows windows and lamps.

Questions and answers

Which is better for gaming, the C4 or the B6?
The C4. It has the same 144Hz VRR ceiling but adds G-Sync and FreeSync certification, a 0.1 ms response time and the faster Alpha 9 processor. The B6 is still a good 120Hz gaming set, just less capable.
Is the B6 worth stepping up to for the bigger screen?
If screen size is your priority, yes. The B6 gives you 65 inches of OLED for a more cinematic view. You give up brightness and the step-up processor, so the C4 still wins on pure picture quality.
Which has the better picture?
The C4. Its evo panel with Brightness Booster is brighter, and the Alpha 9 Gen7 chip handles upscaling and tone mapping better. The B6 uses a dimmer panel and the Alpha 8 Gen3 processor.
Which lasts longer?
Both are OLED sets with similar panel life and the same risk of image retention if static logos sit on screen for hours. Neither has a clear durability edge; the C4's newer processor is the main long-term difference.
Do both support Dolby Vision?
Yes. Both handle Dolby Vision, HDR10 and HLG. The C4 adds OLED Dynamic Tone Mapping Pro for finer HDR adjustment.
Which is better for a bright room?
The C4, because its evo panel is brighter. Neither has an anti-glare coating, so both struggle with direct sunlight or strong window reflections.
