LG G4 OLED evo 4K Smart TV vs Sony Bravia XR A80K 77" OLED TV

Both are 4K OLED TVs with 120 Hz panels, so picture fundamentals are close. The LG G4 is the stronger set: a brighter evo panel, a gallery-style design meant to hang flush, four HDMI 2.1 ports for consoles and PCs, and support for Google Assistant, Alexa and Siri. The 77-inch set is a solid OLED with four HDMI ports and a large base of high ratings, but its listing gives fewer details on brightness, gaming features and design. Buy the LG if you want the best picture and gaming features; buy the 77-inch set if you want a large OLED and its specs fit your room.

  • Choose the LG G4 if you want the brightest OLED picture, four HDMI 2.1 ports for gaming, and a slim gallery design that mounts flush.
  • Choose the 77-inch 4K HDR smart TV if you want a big OLED screen with four HDMI ports and a simpler setup.

What reviewers say

LG G4 OLED evo 4K Smart TV

Reviewers rate the G4 as one of the best OLEDs of 2024, praising its brightness jump over earlier evo panels and its gaming features. Owners like the picture and the flush mount, but many complain about the price and the lack of a stand.

What people mention
  • BrightnessPraisedReviewers say the MLA panel is clearly brighter than the C4, especially in highlights.
  • GamingPraisedOwners and reviewers like the 144 Hz refresh, VRR and four HDMI 2.1 ports.
  • PriceCriticisedBuyers say the G4 costs a lot more than the C4 for a modest picture gain.
  • StandCriticisedOwners complain there is no table stand in the box, only a wall mount.

Sony Bravia XR A80K 77" OLED TV

  • 5 / 580,680 ratings

Owners rate it very highly, with 80,680 ratings averaging 5 out of 5. They praise the contrast, color and sound and treat it as a premium movie set, while a few note brightness limits and OLED care.

What people mention
  • Picture qualityPraisedOwners say the OLED contrast and color make movies look rich and detailed.
  • SoundPraisedReviewers note the panel-based audio is clear enough that many skip a soundbar.
  • BrightnessMixedSome find it dimmer than bright LED sets in sunlit rooms, though fine in dim light.

Questions and answers

Which has the better picture?
The LG G4. Its evo panel is built for higher brightness, which helps HDR highlights and bright rooms. The 77-inch set is still OLED, so blacks and contrast are strong on both.
Which is better for gaming?
The LG G4. It pairs 120 Hz with four HDMI 2.1 ports and low-latency gaming features. The 77-inch set has four HDMI ports, but its 2.1 and variable refresh support are not confirmed.
Is the LG G4 worth stepping up to?
Yes if you watch a lot of HDR content, play on a console or PC, or want a flush wall mount. If you mainly stream shows in a dim room, the 77-inch OLED covers the basics.
Which lasts longer?
Both are OLED, so panel life depends on brightness settings and static content. The LG adds features like pixel refresh and logo dimming that help protect the panel over years of use.
Can I use voice assistants on both?
Yes. Both support Google Assistant and Amazon Alexa. Only the LG G4 also lists Siri support.
Which is easier to set up?
The 77-inch set is simpler: a stand or wall mount and four HDMI inputs. The LG G4's gallery design is meant to hang flush, which takes more careful wall mounting.
