LG UA77 Series 50UA7700PUB 50"

★★★★★ 4.5 (457)

Equipped with the Alpha 7 AI Processor Gen8, the 50-inch 4K LED display upscales content effectively and supports HDR10 and HLG formats. It pairs a robust webOS 25 platform with 300+ free channels and multi-assistant voice control (Alexa, Google, Apple) for effortless streaming and smart home integration. This TV is best for budget-conscious cord-cutters wanting a versatile secondary display for bedrooms or small living rooms, with enough gaming features (VRR, ALLM, FreeSync) for casual console play.
