LG C3 OLED evo 77" 4K Smart TV vs LG C3 65" OLED evo TV

These are the same TV in two sizes: the LG C3 OLED evo, with the α9 Gen6 processor, 120Hz panel, four HDMI 2.1 ports and webOS 23. The 77-inch gives you a much bigger picture for a large room and a real home-theater feel; the 65-inch suits most living rooms and is easier to place. Picture quality, gaming features and build are identical, so the choice comes down to room size and viewing distance, not performance.

  • Choose the LG C3 77-inch if you sit far from the screen or want the most immersive movie and sports picture your room can take.
  • Choose the LG C3 65-inch if your seating is closer or your wall space is limited, and you want the same OLED picture in a tidier size.

  • LG C3 65" OLED evo TV: $1,183.91 at Best Buy (last seen Nov 4)

What reviewers say

LG C3 OLED evo 77" 4K Smart TV

Owners of the C3 line praise the contrast, gaming features and webOS, and most find the 77-inch size worth the jump. Complaints center on brightness in bright rooms, reflections, and the built-in speakers.

What people mention
  • Picture qualityPraisedOwners call the contrast and black levels the main reason to buy.
  • BrightnessMixedFine in dim rooms, but some find it dimmer than expected in daylight.
  • GamingPraised120Hz, VRR and low lag are cited as strong for consoles and PC.
  • SoundCriticisedThe built-in speakers are called thin, with most owners adding a soundbar.

LG C3 65" OLED evo TV

Owners and reviewers rate the C3 as one of the best-value OLEDs of its generation, praising picture quality and gaming features. Complaints center on brightness in bright rooms and on the care OLED needs to avoid burn-in.

What people mention
  • Picture qualityPraisedOwners say dark scenes show detail the LCD sets they replaced could not, with no halo around bright objects.
  • BrightnessCriticisedReviewers note the C3 dims in bright rooms and trails the G3, which limits it to dimmer spaces or controlled light.
  • GamingPraisedConsole owners report smooth 4K 120 Hz play with VRR and low lag on all four HDMI 2.1 inputs.
  • Burn-inMixedSome owners worry about static logos and tickers, and report the TV dimming them automatically.

Questions and answers

Is the 77-inch C3 better than the 65-inch?
Only in size. The panel, processor, ports and smart features are the same. The 77-inch is better if you sit far back; the 65-inch is better if your room is smaller.
Which is better for gaming?
Both are equally good. Each has a 120Hz OLED panel, VRR, ALLM, G-Sync Compatible support and four HDMI 2.1 ports, so consoles and PCs run the same on either.
How far should I sit from each?
For mixed viewing, about 7-10 feet suits the 65-inch and about 9-13 feet suits the 77-inch. Sit closer and the 77-inch can feel overwhelming.
Does the bigger one have better sound?
Not meaningfully. Both use down-firing speakers with Dolby Atmos and AI Sound Pro. A soundbar improves either one.
Is OLED burn-in a concern on both?
Yes, equally. Static logos, news tickers and game HUDs left on for hours can leave marks. Vary content and use the TV's screen-care features.
Should I step up to the 77-inch?
Step up if your seating is far back and your wall can take it. Stay with the 65-inch if the room is small or the screen would sit close.
