LG C4 OLED TV vs LG B5 65" OLED 4K Smart TV

The LG C4 is the better TV of the two. It has a brighter OLED evo panel, the α9 Gen7 processor, four HDMI 2.1 ports with G-Sync and FreeSync, and a 144 Hz VRR ceiling for gaming. The B5 is LG's entry OLED: same self-lit panel benefits and perfect blacks, but a dimmer picture, a weaker processor and fewer gaming features. Buy the C4 for a bright room, a console or a PC; buy the B5 if you watch mostly in a dark room and want the lowest-cost way into OLED.

  • Choose the LG C4 if you game on a PS5, Xbox or PC, watch in a bright room, or want the brightest, most future-proof OLED LG makes at this size.
  • Choose the LG B5 if you watch films and streaming mostly in a dark room and want true OLED blacks without paying for gaming extras you will not use.

Questions and answers

Which is better for gaming, the C4 or the B5?
The C4. It has four HDMI 2.1 ports, G-Sync certification, FreeSync and VRR up to 144 Hz, plus a 0.1 ms response time. The B5 handles 4K 120 Hz but lacks the same certified gaming set.
Is the C4 worth stepping up to over the B5?
Yes for most buyers. The C4 is brighter, has the α9 Gen7 processor and more gaming ports, which shows in HDR highlights and daytime viewing. The B5 makes sense if you watch in a dark room and do not game.
Which has better picture quality?
The C4. Both use OLED for perfect black and wide viewing angles, but the C4's evo panel and Brightness Booster give it more punch in highlights and bright rooms.
Does either TV suffer from burn-in?
Both are OLED, so both carry some burn-in risk with static logos, tickers or desktop taskbars left on for long periods. Owners of the C4 have reported isolated cases. Vary content and use screen-shift settings.
Which is better for a bright living room?
The C4. Its higher brightness copes better with daylight, though neither has an anti-glare coating, so avoid placing either opposite a window.
Do both support Dolby Vision?
The C4 supports Dolby Vision, HDR10 and HLG. The B5's HDR support is narrower, so Dolby Vision content will not look its best on it.
