4K Ultra HD

4x the resolution. 4x the detail.
The higher the resolution, the more detailed a picture can be. So for picture quality that’s really going to wow, a 4K Ultra HD Roku TV is a great choice.
4K TVs have 4x the resolution of HD TVs, delivering incredibly lifelike pictures. Tons of entertainment is available in 4K—and even HD content looks better on a 4K TV, thanks to a feature called "video upscaling". It’s a great experience you’ll love for years to come.

HDR picture-enhancing technologies

While HD and 4K Ultra HD are all about the detail, High Dynamic Range (HDR) is all about rich, vibrant color and striking contrast. You'll see clearer dark scenes and detailed bright scenes for a truly spectacular TV experience.
