LG G4 OLED evo TV vs Sony K77XR80PAEP 77-inch TV

The LG G4 is the better TV for most people: its second-generation MLA panel is noticeably brighter than the Sony Bravia 8, and it comes in five sizes from 55 to 97 inches. The Sony wins on sound and processing polish, with Acoustic Surface Audio+ and Google TV built in. Reviewers rate the G4 among the best OLEDs of its year for HDR impact; owners of the Sony praise its natural picture and built-in audio but note it is dimmer and has only two HDMI ports.

  • Choose the LG G4 if you want the brightest OLED picture, a size other than 77 inches, or four full-bandwidth HDMI 2.1 ports for consoles and a PC.
  • Choose the Sony Bravia 8 if you want strong built-in sound, Google TV with Google Assistant, and Sony's motion and upscaling processing.

Questions and answers

Which is better for a bright living room?
The LG G4. Its MLA panel holds up better against window light and gives HDR highlights more punch. The Sony is better suited to a darker room where its contrast shines.
Which has better sound without a soundbar?
The Sony. Acoustic Surface Audio+ vibrates the panel itself, so dialogue and effects come from the picture. The LG's down-firing speakers are serviceable but flat.
Is the LG G4 worth stepping up to over the Sony?
If you game on a console or PC, want a size other than 77 inches, or watch a lot in daylight, yes. If you mostly watch film in a dim room and want built-in sound, the Sony is enough.
Which is better for gaming?
The LG G4. Four HDMI 2.1 ports let you connect a console, a PC and a soundbar without a switcher. The Sony has only two HDMI ports, though both support VRR and ALLM.
Which lasts longer?
Both are OLED and age similarly. The LG's brighter panel may run hotter at high brightness, so keep brightness moderate for mixed viewing. Neither has a clear longevity edge.
Do both support Dolby Vision and Dolby Atmos?
Yes, both support Dolby Vision HDR and Dolby Atmos passthrough. The Sony's built-in Atmos effect is more convincing because of its screen-speaker design.
