A 4K Ultra HD TV has 8.3 million pixels which is four times the pixel resolution and detail compared to conventional high-definition TV (HDTV). This means bigger, more vibrant displays providing an immersive experience, which lets you get closer to the big screen without seeing pixels. Look for CTA’s 4K Ultra HD logo on TVs that meet these criteria.
Most 4K Ultra HD TVs are “Connected” or “Smart,” which means they support streaming apps. These apps can deliver 4K Ultra HD content without the need for any additional devices.

4K Ultra HD TVs contain video processing to automatically make lower resolution content look better. This means that any content received by the TV will be made to look like it has more pixels than it does. While almost all video can be upscaled to look better, final image quality will vary based on the original content quality.
