LG OLED55G56LS

The LG OLED55G54LW and LG OLED55G56LS are extremely close premium OLED TVs designed for high-end home entertainment, gaming, and cinematic viewing. Both models offer a 55-inch 4K OLED panel, 120Hz refresh rate, Dolby Vision, Dolby Atmos, VRR up to 165Hz, and LG’s latest α11 AI Processor Gen2. For gamers and movie enthusiasts, the overall experience is nearly identical with deep blacks, excellent motion handling, and strong smart TV features powered by WebOS 25. The main differences are subtle and mostly related to connectivity details and mounting configuration, making this comparison more about installation preference and future-proofing rather than core performance.

Verdict

The LG OLED55G54LW is the slightly better overall choice thanks to its more complete HDMI 2.1 feature set, including QFT and QMS support across all four ports along with a more versatile 300 x 300 VESA mount. It is better suited for gamers and advanced home theater setups. The LG OLED55G56LS remains an excellent alternative for users who want the same flagship OLED picture quality and smart features at potentially better pricing or availability.
