4K on Xfinity: What’s New and How to Watch

The Olympic Games Tokyo 2020 Live Coverage in 4K

Providing our customers with the best viewing experiences is a top priority and this includes giving them access to 4K UHD programming from TV networks, movie studios, and streaming services who make it available. Whether customers are watching TV through Xfinity X1 or Xfinity Flex, we strive to offer them the best viewing experience. This goal includes access to 4K UHD programming from TV networks, movie studios, and streaming services such as Netflix, Amazon Prime Video and YouTube.

Additionally, Xfinity X1 customers can watch live 4K UHD events when available, including the Olympic Games Tokyo 2020 from July 23-Aug. 8.

For the first time ever in the U.S., the Olympics will be available live in 4K Dolby Vision HDR with Dolby Atmos immersive audio, and X1 will offer customers full access. Live coverage will be available in most markets and include the Opening and Closing ceremonies and every night of NBC primetime show, which will showcase popular sports like gymnastics, track & field, swimming, diving, and beach volleyball.

Additionally, customers can catch:

  • Men’s and women’s tennis on Olympic Channel (July 24-Aug. 1)
  • Men’s golf on Golf Channel (July 29-Aug. 1)
  • Wrestling on Olympic Channel (Aug. 1-7)
  • Women’s golf on Golf Channel (Aug. 4-7)

What is 4K TV?

4K UHD resolution is four times full HD, providing a clearer, more vivid picture. Current HDTV offers 1,920 pixels (tiny dots that make up the picture) across the width of the screen - the more pixels, the sharper the image. With 4K technology, the number of pixels across the picture is doubled to 3,840 (approximately four thousand or "4K"), and the vertical scanning lines are double as well, from 1080p to 2160p.

Watching 4K content with Xfinity TV

4K HDR set top boxes are available for X1 (XG1v4 or Xi6) and Xfinity Flex (Xi6) customers (they must also have a 4K television and 4K-capable HDMI cord in order to watch 4K programming).

Customers can use their Xfinity Voice Remote to say "4K" (or search "4K") to be taken to a 4K UHD landing page that displays all 4K programming available.

When X1 or Flex is set up, it will automatically be set to the highest video output resolution possible for your TV, including 4K UHD. To make sure your box is set to 2160 resolution, say “device settings” into your voice remote and from there select “video display.” On X1 or Flex, if you choose to view On Demand content (for free, rental or purchase) that's available in 4K, playback will automatically default to the appropriate 4K color depth based on your TV’s capabilities.
