Picture Quality and Processing Power
The heart of any modern TV lies in its processor, and here Sony takes a commanding lead. The Cognitive Processor XR doesn't just upscale content—it intelligently analyzes and enhances each scene in real time, replicating how the human brain processes visuals. This results in superior depth, texture, and contrast that LG's α9 Gen 5 simply cannot match consistently. While the LG OLED77C2 offers impressive brightness thanks to its Evo panel, the Sony A80J's image processing creates a more natural, film-like image that enthusiasts crave. In side-by-side comparisons of 4K HDR content, the Sony reveals finer details in shadows and highlights without introducing artificial sharpening artifacts that occasionally plague the LG.
Color Accuracy and Viewing Angles
Both sets deliver the perfect blacks and infinite contrast that only OLED can provide, but Sony's factory calibration is noticeably superior. Out of the box, the Bravia XR A80J sits closer to the ideal color temperature and gamma curve, requiring minimal adjustment for critical viewing. LG's C2 series has improved in this regard, yet still tends to push blues and skin tones slightly off in certain presets. When viewed from extreme angles—common in large living rooms—the Sony maintains color volume and saturation better, making it the superior choice for group movie nights.
Gaming Performance and Features
Gamers will find both TVs highly capable with 4K at 120Hz, VRR, and ALLM support, but the devil is in the details. The Sony Bravia XR A80J edges ahead with its Auto HDR Tone Mapping and lower input lag in Game Mode. Its dedicated Game Menu provides quick access to picture adjustments without leaving the game, a thoughtful touch LG has yet to perfect. While the LG OLED77C2 supports the latest HDMI 2.1 features and Cloud Gaming apps through webOS, its aggressive motion smoothing can sometimes interfere with fast-paced titles unless manually disabled. For serious console gamers with PS5 or Xbox Series X, the Sony simply feels more responsive and refined.
Smart Platform and Daily Usability
Here the competition tightens. LG's webOS 22 remains one of the snappiest and most intuitive interfaces on the market, with excellent remote pointing functionality and quick app switching. Sony runs Google TV, which offers a richer selection of apps and better content recommendations powered by Google’s vast ecosystem. Voice control on both is excellent, but Sony’s integration with Google Assistant feels more seamless for smart home users. The A80J also includes better built-in calibration tools for enthusiasts who want to fine-tune their set using professional equipment.
Sound Quality
Neither TV will replace a dedicated soundbar for audiophiles, but Sony’s Acoustic Surface Audio+ technology vibrates the screen itself to create a more immersive soundstage that matches the on-screen action. The LG’s 40W 2.2 channel system is louder but lacks the precision and spatial accuracy of the Sony. Both support Dolby Atmos passthrough, yet the Sony renders height effects more convincingly when paired with compatible AV receivers.
Who Should Buy Which?
Choose the Sony Bravia XR A80J if:
- You prioritize reference-level picture processing and accuracy
- You want the most cinematic OLED experience available today
- You value better out-of-box calibration and motion handling
- You are willing to pay a premium for proven performance
Choose the LG OLED77C2 if:
- You prefer LG’s webOS interface and Magic Remote
- You want potentially higher peak brightness in well-lit rooms
- You find the LG at a significantly lower street price
- You are deeply embedded in the LG ecosystem with other devices
Final Verdict
The Sony Bravia XR A80J is the superior choice for most buyers seeking a no-compromise 77-inch OLED television. Its Cognitive Processor XR delivers tangible improvements in every aspect of picture quality that truly matter—detail, motion, and color fidelity—earning it a solid 7/10 score compared to the LG’s mediocre 5/10 in this head-to-head.
- Confirmed OLED performance with industry-leading processing
- Superior factory calibration and natural image reproduction
- Better motion handling for both sports and fast gaming
- More immersive Acoustic Surface Audio technology
- Proven 4K 120Hz gaming features with lower input lag
While the LG OLED77C2 is no slouch and may appeal to those who prioritize raw brightness or LG’s ecosystem, it falls short of the refined excellence Sony brings to the table. If you demand the best large-screen OLED experience available, invest in the Sony Bravia XR A80J—you won’t regret it. The difference is visible from the very first scene.
