LG C5 77-inch OLED evo 4K Smart TV vs LG OLED42C6PUA 42" OLED evo C6

These are the same OLED technology at opposite ends of the size range, so the choice is about the room, not the panel. The 77-inch C5 is the better movie and living-room TV: a bigger OLED evo panel, a 144Hz refresh rate, Wi-Fi 6E and four HDMI 2.1 ports. The 42-inch C6 is a newer generation with the brighter Alpha 11 processor, Dolby Vision and Atmos, and a 165Hz VRR ceiling, which suits a desk, a bedroom or a console setup. Owners of both lines praise the blacks and the gaming features; the C5's weak point is its built-in sound, and the C6's is its small size for group viewing.

  • Choose the LG C5 77-inch if you want the biggest OLED picture for a living room, watch movies with others and need Wi-Fi 6E and four HDMI 2.1 ports.
  • Choose the LG C6 42-inch if you sit close, game at high frame rates or have a small room, and want the newer processor with Dolby Vision and Atmos.

What reviewers say

LG C5 77-inch OLED evo 4K Smart TV

  • 4.9 / 52,240 ratings

Owners rate the C5 very highly, at 4.9 out of 5 from 2,240 ratings. They praise the deep blacks, the smooth 144Hz motion and the gaming features. The main complaints are brightness in bright rooms and the size and weight of a 77-inch set.

What people mention

Questions and answers

Which is better for a bright living room?
The C6 has the newer Alpha 11 processor and Brightness Booster, so it handles reflections and daylight slightly better per inch. The C5's larger panel still wins on immersion if you can control the light.
Which is better for gaming?
The C6 edges ahead with G-Sync, FreeSync Premium, ALLM and a 165Hz VRR ceiling. The C5 counters with four HDMI 2.1 ports and a 144Hz panel, which is plenty for most consoles.
Which lasts longer?
Both use OLED panels with similar lifespans and OLED care features. The C5 bundle adds a multi-year protection plan, which matters more than the panel difference.
Is the C6 worth stepping up to over the C5?
Only if size is not the priority. The C6 is a newer generation with better processing and Dolby Vision, but it cannot match a 77-inch screen for movies.
Do I need a soundbar for either?
The C5 benefits most from one given its size. The C6's speakers are well reviewed for a 42-inch set, but a soundbar still improves both for films.
