LG C6 Series OLED 4K Smart TV vs Sony BRAVIA 8 77" OLED TV

Both are 77-inch 4K OLEDs at 120 Hz with HDMI 2.1 and Dolby Vision, so the picture fundamentals are close. The LG C6 pushes higher brightness with its Brightness Booster Pro panel and Alpha 11 processor, and it is the lighter set to hang. The Sony BRAVIA 8 wins on sound, with an acoustic surface that uses the screen as the speaker, and on Google TV plus AirPlay and Chromecast built in. Owners rate the Sony well but not perfectly, and reviewers consistently praise LG's C-series for gaming features and value. Buy the LG for a bright room and gaming; buy the Sony if you skip a soundbar and want Google TV.

  • Choose the LG C6 if you watch in a bright room, game on a console or PC, and want the brightest picture of the two.
  • Choose the Sony BRAVIA 8 if you want theater-like sound from the screen itself and prefer Google TV with AirPlay and Chromecast built in.

What reviewers say

LG C6 Series OLED 4K Smart TV

Owners and reviewers highlight the C6 as a major step forward for bright-room OLED performance thanks to the Alpha 11 processor. It is praised for its color accuracy and gaming features, though its weight and long-term pixel care remain standard OLED considerations.

What people mention
  • BrightnessPraisedThe Brightness Booster Pro technology makes this set significantly more visible in sunlit rooms than previous generations.
  • ProcessingPraisedThe Alpha 11 AI Processor Gen3 is noted for providing a smoother, more personalized experience without lag.
  • BuildMixedWhile the flat screen is sleek, the 84 lb weight of the 77-inch unit makes mounting a heavy-duty task.

Sony BRAVIA 8 77" OLED TV

  • 4.2 / 597 ratings

  • SoundPraisedReviewers say the screen-as-speaker audio is clearer and fuller than most TVs.

  • GamingPraisedGamers like the 120 Hz panel, VRR and four HDMI 2.1 ports.

Questions and answers

Which is better for a bright living room?
The LG C6. Its Brightness Booster Pro panel is rated up to 3.2x brighter than older OLEDs, which holds up better against window light. The Sony is a standard OLED panel and will look dimmer in daytime.
Which has better built-in sound?
The Sony BRAVIA 8. Its Acoustic Surface Audio vibrates the screen itself and outputs 56 W, which is closer to a soundbar than typical TV speakers. The LG's speakers are fine for news but not for movies.
Which is better for gaming?
They are close. Both do 120 Hz with HDMI 2.1 and variable refresh rate. The Sony puts all four HDMI ports on the side, which is easier to reach, while the LG leans on its low-latency game mode and brighter panel.
Is the Sony worth stepping up to over the LG?
Only if sound and Google TV matter more than brightness. If you already own a soundbar and watch in a bright room, the LG is the stronger pick. If the TV is the whole system, the Sony's screen-speaker design earns its place.
Which lasts longer?
Neither has a clear edge on lifespan. The LG adds OLED Care features that reduce burn-in risk, which helps if you leave news tickers or game HUDs on screen. The Sony has no comparable panel-care feature listed.
Which is easier to wall mount?
The Sony. It weighs about 71 lb at 77 inches and uses a standard 300 x 300 mm VESA pattern. The LG is about 84 lb, though it ships with its mount included.
