The Westinghouse MX Series is a 55-inch Mini-LED 4K Roku TV with quantum-dot color, local dimming, and Dolby Vision, HDR10, and HLG support. It adds MEMC motion smoothing and HDMI 2.1 with eARC for consoles and soundbars. At $459.99 at Best Buy as of November 7, 2026, it is the only new price listed, so there is no recent range to compare against. Mini-LED at this size and price is unusual; most budget 55-inch sets are edge-lit LCD.
