LG B4 4K OLED TV vs LG C5 OLED evo 4K Smart TV

Buy the C5 if you want the better picture and gaming set. Its OLED evo panel with Brightness Booster is brighter than the B4's standard OLED, and the α9 Gen8 chip handles upscaling and processing better than the B4's α8. The C5 also adds 144Hz, G-Sync, FreeSync Premium, Wi-Fi 6 and Dolby Atmos, while the B4 tops out at 120Hz, Wi-Fi 5 and 20W stereo sound. The B4 is the sensible pick if you mainly watch movies and stream, and you don't need the extra brightness or gaming features. Owners of both praise the picture; C5 buyers single out the 144Hz smoothness and brightness, while B4 owners accept dimmer HDR highlights as the trade-off for the lower tier.

  • Choose the LG B4 if you want a solid OLED for movies and streaming and don't need 144Hz, G-Sync or the extra brightness.
  • Choose the LG C5 if you game on a PC or console, watch in a bright room, or want the better processor and Dolby Atmos.

Questions and answers

Which is better for gaming, the B4 or the C5?
The C5. It runs up to 144Hz with G-Sync and FreeSync Premium, while the B4 caps at 120Hz with VRR and ALLM. Both have four HDMI 2.1 ports, so consoles work well on either.
Is the C5 noticeably brighter than the B4?
Yes. The C5 uses an OLED evo panel with Brightness Booster, which raises peak brightness over the B4's standard OLED panel. In a bright room the difference shows most in HDR highlights.
Which lasts longer?
Both are OLED sets with similar panel life. The C5 ships on webOS 25 with LG's Re:New program promising up to five years of updates, so it should stay current longer on software.
Do I need the C5 if I mostly watch movies?
Not necessarily. The B4 handles Dolby Vision and HDR10 well for movie nights. Step up to the C5 if you want more brightness, Dolby Atmos or the better α9 processing.
Does the B4 come in bigger sizes than the C5?
Yes. The B4 comes in 48, 55, 65, 77 and 83 inches, while this C5 listing is the 48-inch model. If you need a large screen, the B4 covers more sizes.
Is the C5 worth stepping up to over the B4?
For gamers and bright rooms, yes. The 144Hz panel, G-Sync, FreeSync, Wi-Fi 6 and Dolby Atmos are real upgrades. For a dim room and basic streaming, the B4 covers the essentials.
