LG C5 Series OLED evo TV vs LG C6 Series OLED TV

The C6 is the better buy for most people. It has the faster 165Hz panel, a newer processor, and a much larger and stronger owner record (4.8 from 2,339 ratings versus 4.4 from 46). Both are 42-inch OLED evo sets with perfect black, Dolby Vision, Dolby Atmos, four HDMI 2.1 ports and 0.1ms response, so the C5 is still a fine movie and gaming TV. The C5's weak points are its cluttered webOS menus, remote failures and reports of dead lines and blocky near-black scenes; the C6 addresses the panel speed and processing but shares the same webOS complaints.

  • Choose the LG C5 if you want a proven 42-inch OLED for movies and console gaming and the C6's extra refresh headroom does not matter to you.
  • Choose the LG C6 if you want the fastest 42-inch OLED LG makes, with 165Hz, a newer Alpha processor and a far stronger owner track record.

Prices

  • LG C5 Series OLED evo TV: $795.80 at Walmart (checked today)
  • LG C6 Series OLED TV: $899.99 at Walmart (last seen Nov 9)
  • Difference: the LG C5 Series OLED evo TV is $104.19 cheaper than the LG C6 Series OLED TV at the latest prices (Nov 9 and Nov 10)

Questions and answers

Which is better for gaming, the C5 or the C6?
The C6. Its 165Hz panel beats the C5's 120Hz, and it adds Game Optimizer and Dashboard. Both have 0.1ms response, VRR, G-Sync, FreeSync Premium and four HDMI 2.1 ports.
Is the C6 worth stepping up to from the C5?
Yes for most buyers. You get a faster panel, a newer processor and a much stronger owner record. The C5 remains a solid OLED if you mainly watch movies and stream.
Which lasts longer?
There is no long-term reliability data for either. The C6 has far more owner ratings and fewer reported faults, while some C5 owners report dead lines after about six weeks.
Do both handle dark rooms well?
Yes. Both use OLED evo panels with self-lit pixels for perfect black. Some C5 owners report blocky near-black scenes; the C6 has fewer such complaints.
Which has better sound?
Neither is a standout. Both use two speakers with Dolby Atmos, and C5 owners report quiet dialogue. Plan on a soundbar for either.
Do both run the same apps?
Yes. Both run LG's webOS with major streamers and free LG Channels. The C6 ships with the newer webOS 26.
