Mini-LED backlighting and QLED technology deliver deep contrast and color, while a 120Hz refresh rate with Dolby Vision IQ ensures fluid, vivid motion. Roku’s platform provides 500+ free live channels and an art mode that transforms the TV into a wall-mounted digital gallery. It’s ideal for cord-cutters and casual gamers wanting a sleek, wall-hugging design, simple smart home integration, and solid picture quality at a budget-friendly price.
