LG QNED80 55" vs Roku Plus Series 55"
LG's QNED80 commands a $300 premium by delivering superior picture quality through its Quantum Dot NanoCell technology and 700-nit brightness, matched with native 120Hz refresh rate and a snappier 10ms gaming input lag. Roku's Plus Series counters with excellent value, featuring Dolby Atmos audio, Wi-Fi 6 connectivity, and equally sharp 4K resolution—though its 60Hz native refresh and slower 13ms response time limit gaming performance. Both TVs offer comprehensive smart features and voice control, but LG's α8 AI Processor provides noticeably better upscaling and processing. For gaming enthusiasts and cinephiles seeking premium performance, the QNED80 justifies its cost. Budget-conscious buyers wanting solid everyday 4K streaming will find the Roku Plus Series delivers surprising competence at nearly half the price. Choose LG for cutting-edge features; pick Roku for intelligent spending.
