LG C4 OLED evo 83-inch TV vs Sony K77XR80PAEP 77-inch TV

The LG C4 is the stronger TV for most people. It has four HDMI ports, full HDMI 2.1 bandwidth on all of them, Nvidia G-Sync certification and LG's mature webOS platform, and the C-series is the set reviewers most often recommend in this class. The Sony XR80 is a step down in the lineup: two HDMI ports and a 3-out-of-5 owner rating across 1,100 ratings point to a mid-tier panel rather than a flagship. Buy the LG unless the Sony's size and assistant support matter more to you than connectivity and gaming features.

  • Choose the LG C4 if you want four HDMI inputs, G-Sync VRR for a PC or console, and the OLED picture the C-series is known for.
  • Choose the Sony XR80 if you want a 77-inch OLED with Google Assistant, Alexa and Siri built in and can live with two HDMI ports.

Questions and answers

Which is better for gaming?
The LG C4. It has four HDMI ports and Nvidia G-Sync VRR certification, which the Sony listing does not mention. The Sony's two ports also fill up fast with a console and a soundbar.
Which has the better smart TV system?
They trade off. LG's webOS is fast and has every major app but pushes more promoted content. Sony's Google TV is cleaner and adds Google Assistant, Alexa and Siri support.
Is the extra screen size worth it?
If your room can take an 83-inch set, yes. The jump from 77 to 83 inches is noticeable at normal seating distances, and the LG also adds two HDMI ports and G-Sync.
Which lasts longer?
Both are OLED panels with similar lifespans. LG's C-series has a longer track record with reviewers and owners; the Sony's 3-out-of-5 rating from 1,100 ratings is a caution flag.
Do I need an anti-glare screen?
Neither set lists an anti-glare coating. In a bright room, plan seating and curtains around reflections on both.
Is the Sony worth stepping up to?
Only if you specifically want Siri, Alexa or Google Assistant built in. On ports, gaming features and owner satisfaction, the LG is the better set.
