Sony BRAVIA XR8B 77" OLED TV vs LG OLED Flex

Pick the Sony K-77XR8B if you want a big, conventional 77-inch OLED with Google TV, Apple HomeKit and Dolby Atmos built in. Pick the LG OLED Flex if you want a smaller 42-inch screen that bends from flat to curved and can be used close up for gaming or a desktop setup. The Sony is the safer living-room TV; the Flex is a niche, flexible display. Owners rate the Sony well overall, while the Flex's appeal depends entirely on whether you want the bendable screen.

  • Choose the Sony BRAVIA XR8B if you want a large 77-inch OLED for movies and sports in a living room, with Google TV and Apple HomeKit built in.
  • Choose the LG OLED Flex if you want a 42-inch bendable OLED that switches between flat and curved for gaming or a desk setup.

What reviewers say

Sony BRAVIA XR8B 77" OLED TV

  • 4.4 / 5135 ratings

Rated 4.4 out of 5 from 135 ratings, the XR8B draws praise for its OLED picture and Google TV interface. Buyers mostly flag brightness and price as the sticking points.

What people mention
  • Picture qualityPraisedOwners describe deep blacks, vivid color and crisp 4K detail.
  • BrightnessCriticisedSome say the panel struggles in bright, sunlit rooms.
  • SetupPraisedBuyers report quick setup and a smooth Google TV experience.
  • SoundPraisedThe built-in speakers with Dolby Atmos are called good enough without a soundbar.

LG OLED Flex

Reviewers praise the LG OLED Flex for its unique adjustable curvature and excellent picture quality. However, many criticize its high price and the motorized mechanism as a novelty that may not justify the cost.

What people mention
  • CurvaturePraisedReviewers love the ability to switch between flat and curved modes for different content.
  • Picture qualityPraisedOwners consistently praise the OLED panel's perfect blacks and vibrant colors.
  • PriceCriticisedMany complain that the Flex costs much more than equivalent OLED TVs without the bending feature.
  • Motorized mechanismMixedSome find the motorized curvature adjustment slow and worry about long-term durability.

Questions and answers

Which is better for a living room?
The Sony. Its 77-inch screen fills a living room and it has Dolby Atmos and Google TV built in. The LG Flex is a 42-inch set better suited to a desk or small room.
Which is better for gaming?
Both run at 120 Hz on OLED panels. The LG Flex adds a curved mode that some players prefer up close, while the Sony gives you a much larger screen for couch play.
Does the LG OLED Flex really bend?
Yes. The screen motorized-switches between flat and curved. That is its main feature and the reason to consider it over a standard OLED.
Which has better sound?
The Sony. It lists Dolby Atmos and five speakers. The LG Flex does not list Dolby Atmos, so plan on a soundbar for either.
Is the Sony worth stepping up to over the LG Flex?
If you want one big TV for the whole room, yes. The Sony's 77-inch screen and Google TV make it the more complete living-room set. The Flex only wins if you specifically want a small bendable screen.
Do both have four HDMI ports?
Yes. Both list four HDMI inputs, and both are 4K OLED sets with a 120 Hz refresh rate.
