LG OLED55B56LA
The Sony KD-55X85L and LG OLED55B56LA are both premium 55-inch 4K TVs with 120Hz panels, Dolby Vision support, and advanced gaming features. However, they target slightly different buyers. Sony focuses on accurate picture processing, Full Array LED backlighting, and the Google TV ecosystem, making it a strong all-round entertainment choice. LG takes the lead with OLED technology, pixel-level dimming, faster response times, and gaming-focused enhancements such as G-Sync and FreeSync support. If picture quality and gaming performance are priorities, the differences become much more noticeable despite both TVs sharing similar screen size and resolution.
Verdict
The LG OLED55B56LA is the stronger overall TV thanks to its OLED panel, superior contrast, perfect black levels, wider gaming support, and near-instant response time. It is ideal for movie enthusiasts and serious gamers. The Sony KD-55X85L remains an excellent choice for users who prefer Google TV, Sony's image processing, and a Full Array LED display at a potentially lower price point. For most buyers seeking the best viewing experience, LG holds the advantage.
