LG OLED evo C4 65-Inch 4K Smart TV vs LG B5 Series OLED TV

Both are 65-inch 4K OLEDs with 120Hz panels, four HDMI inputs, Dolby Vision and Dolby Atmos, so the picture fundamentals are close. The C4 is the stronger set: LG's Alpha 9 Gen7 processor, Brightness Booster, four full-bandwidth HDMI 2.1 ports and the Magic Remote put it ahead for movies, gaming and upscaling. The B5 runs the newer webOS 25 and Wi-Fi 6 on a step-down Alpha 8 Gen2 chip with a 20W 2.0 speaker system, so it suits buyers who want OLED contrast and the latest software without paying for the flagship processing. Owners rate the C4 highly, and the B5 is the value pick in LG's OLED line.

  • Choose the LG C4 if you want the best picture processing LG offers at this size, four gaming-ready HDMI 2.1 ports and the point-and-click Magic Remote.
  • Choose the LG B5 if you want OLED blacks and the newest webOS with Wi-Fi 6, and you can live with a step-down processor and basic built-in sound.

Questions and answers

Which is better for gaming, the C4 or the B5?
Both give you 4K at 120Hz, VRR and ALLM on all four HDMI ports, so consoles work well on either. The C4 adds the Alpha 9 processor and Brightness Booster, which help HDR games look punchier.
Is the C4 worth stepping up to over the B5?
Yes if you watch a lot of lower-quality cable or streaming and want better upscaling, or if you want the brightest OLED picture LG makes at this size. If you mostly watch 4K sources and use a soundbar, the B5 covers the basics.
Which has better sound?
Both use a 2.0 channel setup with Dolby Atmos, and neither fills a room on its own. The B5 lists 20W output; the C4's advantage is processing, not speakers. Plan on a soundbar or AV receiver with either.
Does the B5 have newer software?
Yes. The B5 ships with webOS 25 and Wi-Fi 6, while the C4 runs webOS 24 and an older Wi-Fi standard. The C4 still gets app updates, but the B5 starts on the newer platform.
Which lasts longer?
Both are OLED panels with the same burn-in risk, so lifespan depends on viewing habits more than the model. Vary content, avoid static logos or tickers for hours, and enable the screen-shift and logo-dimming settings on either set.
Which is better in a bright room?
The C4, because Brightness Booster raises peak output over the standard B5 panel. Neither matches a bright LCD in a sunlit room, so curtains still help during the day.
