LG OLED evo C4 Series 4K Smart TV vs LG C3 OLED evo 65-Inch TV

Both are 65-inch LG OLED evo sets with 120Hz panels, four HDMI ports, Dolby Vision and Dolby Atmos, so the picture experience is close. The C4 is the newer generation: a faster processor, higher peak brightness from Brightness Boosting, a 0.1 ms response time for gaming, and webOS 24. The C3 is the prior generation with the a9 Gen6 chip, 40W 2.2-channel sound and webOS 23, and it remains a strong set. Buy the C4 for the brightest picture and the longest useful life; buy the C3 if you want the same OLED look and do not need the extra brightness.

  • Choose the LG C4 if you want the brightest OLED picture LG makes at this size, the newest processor and webOS, and the best gaming responsiveness.
  • Choose the LG C3 if you want the same self-lit OLED picture and 120Hz panel and are fine with the previous-generation processor and brightness.

  • LG OLED evo C4 Series 4K Smart TV: $849.00 at Amazon (last seen Nov 13)
  • LG C3 OLED evo 65-Inch TV: $1,238.91 at Best Buy (last seen Nov 12)
  • Difference: the LG OLED evo C4 Series 4K Smart TV is $389.91 cheaper than the LG C3 OLED evo 65-Inch TV at the latest prices (Nov 12 and Nov 13)

Questions and answers

Which is better for gaming, the C4 or the C3?
The C4. It quotes a 0.1 ms response time and runs the newer processor, which helps with motion and input lag. Both give you 120Hz and four HDMI ports.
Is the C4 much brighter than the C3?
Yes, but the gap shows most in a bright room and in HDR highlights. In a dark room both look close, because OLED blacks are the same.
Which lasts longer?
Neither has a stated lifespan advantage. The C4 is a year newer, so it will get webOS updates for longer. OLED panels in both can show static-image burn-in over years of news tickers or game HUDs.
Do both support Dolby Vision and Dolby Atmos?
Yes. Both handle Dolby Vision HDR and Dolby Atmos, and both have FILMMAKER MODE. The C3 states a 40W 2.2-channel speaker system; the C4 does not state wattage.
Is the C4 worth stepping up to over the C3?
If you watch in a bright room, game seriously, or keep a TV for many years, yes. If you watch mostly at night and want the same OLED look, the C3 covers it.
Do both work with Alexa and Google Assistant?
Yes. Both list Amazon Alexa and Google Assistant support, and the C3 also lists Apple Home.
