The 4K Ultra HD resolution (3840 x 2160) delivers four times the detail of 1080p Full HD, making it well-suited for streaming 4K content, movie nights, and general daily viewing. HDR support adds enhanced contrast and a wider color palette when playing HDR-compatible content, bringing more depth to highlights and shadows.

This allows hands-free control of power, volume, channel switching, and content search through a compatible smart speaker or voice assistant. Apple users can also take advantage of AirPlay to wirelessly stream content from iPhones, iPads, and Macs directly to the TV screen. The high-speed HDMI inputs support full 2160p picture with digital surround sound for connecting game consoles, Blu-ray players, or soundbars. As a renewed unit, this TV has been professionally inspected and tested to meet working standards, offering the same feature set as new at a reduced cost.
