LG C6 Series OLED 4K Smart TV vs LG C5 OLED evo 4K Smart TV

Both are LG OLED evo sets with perfect blacks, Dolby Vision and four HDMI 2.1 ports, so picture quality is close. The C6 is the newer generation: the Alpha 11 Gen3 chip, a 165Hz panel, webOS 26 and built-in Gemini and Copilot assistants. The C5 runs the Alpha 9 Gen8 chip, a 120Hz panel and webOS 25, and it has far more owner feedback behind it. Buy the C6 for the brightest, fastest panel and the newest software; buy the C5 if you want the proven set and don't need the extra refresh headroom.

  • Choose the LG C6 if you want the newest OLED evo panel, a 165Hz refresh rate and the latest webOS with built-in AI assistants.
  • Choose the LG C5 if you want a well-established OLED evo set with a huge base of owner reviews and the same core picture technology.

Questions and answers

Which is better for gaming, the C6 or the C5?
Both have four HDMI 2.1 ports, 0.1ms response and G-Sync plus FreeSync Premium. The C6 adds a 165Hz panel, which helps if you play on a fast PC; the C5 tops out at 144Hz VRR.
Is the C6 worth stepping up to over the C5?
If you want the brightest panel, the newest processor and webOS 26 with built-in AI assistants, yes. If you mainly watch movies and shows, the C5 delivers the same OLED blacks and Dolby Vision.
Which has better sound?
The C5 lists a 40W 2.2-channel speaker system, which is more specific than the C6's Dolby Atmos support. Either way, a soundbar improves both.
Which lasts longer?
Both use LG OLED evo panels with OLED Care protection, and neither has a documented lifespan edge. The C5 has far more owner history behind it, while the C6 is newer.
Do both support Dolby Vision and Dolby Atmos?
Yes. Both list Dolby Vision for HDR and Dolby Atmos for audio, along with HDR10 and HLG.
Which is better in a bright room?
The C6 claims Brightness Booster Pro at up to 3.2x brighter. The C5 uses Bright Room Ready boosting with a UL-certified glare-free coating. Both handle daylight better than older OLEDs.
