LG 43NU870BPLA

The Samsung UA43DUE77AKLXL and LG 43NU870BPLA are both 43-inch 4K TVs with 60Hz panels, but they take different approaches to picture, sound and gaming. Samsung uses its Crystal Processor 4K, HDR10+ support and Motion Xcelerator, while LG combines a Direct Nano LED display with the Alpha 7 AI Processor 4K Gen9, Dolby Atmos and AI-based picture processing. Both offer three HDMI 2.1 ports, eARC and smart TV platforms, making them suitable for streaming and console gaming. The LG has a stronger feature set for gamers and audio, while Samsung offers useful HDR10+ support and a familiar Tizen experience.

Verdict

The LG 43NU870BPLA is the stronger all-round choice if gaming, sound quality and advanced picture processing are priorities. Its Dolby Atmos support, VRR up to 60Hz, Game Optimizer and AI processing give it an edge for modern entertainment. The Samsung UA43DUE77AKLXL is still a compelling option for users who prefer Tizen, HDR10+ support, Samsung's ecosystem and a straightforward 4K viewing experience.
