      What is 4K streaming?

      4K describes the picture quality you can get while you’re streaming, as long as you have a 4K compatible TV. With 4x the pixels as standard HD picture quality, 4K is crisp and clear so you’ll experience lifelike detail.

        You can use a 4K streaming device, like Roku Express 4K, on a non-4K TV as long as it has an HDMI port, but you’ll only be able to stream in HD picture quality. Even if you don’t have a 4K TV, you can still enjoy smooth streaming with Roku Express 4K thanks to its dual-band Wi-Fi® connection.


          Do I need a 4K streaming device?
