The LG OLED77C3 77" OLED 4K TV. And the Sony A90J 77" OLED 4K TV both rely on self-emissive OLED panels that deliver the same native 4K resolution, 120 Hz refresh rate. And wide color coverage, yet they diverge in processing, operating system, and sound delivery according to aggregated reviewer measurements and manufacturer specifications. Public benchmarks show the LG OLED77C3 running the more recent webOS with quicker navigation. And broader app support, while its alpha blending and motion handling receive consistent praise for everyday viewing. The Sony A90J, equipped with Acoustic Surface Audio that vibrates the screen itself, earns repeated notes for clearer dialogue. And a more integrated soundstage without requiring a separate soundbar in modest rooms. Brightness, contrast uniformity, and input lag figures sit close enough that differences often come down to user interface habits rather than raw picture metrics. Bottom line: choose the LG OLED77C3 for a fluid smart-TV experience inside the webOS environment or the Sony A90J when stronger built-in audio matters more.

Verdict: Pick LG OLED77C3 if you prioritize a straightforward Smart TV platform and prefer LG’s webOS ecosystem. Pick Sony A90J if integrated audio performance is a priority.
