Whether customers are watching TV through Xfinity X1 or Xumo Stream Box from Xfinity, we strive to offer you the best viewing experience. This mission includes access to 4K Utra HD (UHD) and enhanced 4K programming from TV networks, movie studios, and streaming services such as Netflix, Amazon Prime Video and YouTube, whenever it is available.
What is 4K TV?
Standard 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.
What is Enhanced 4K TV?
Enhanced 4K offers crisp quality, brighter colors, and immersive audio delivered like you’ve never experienced before. Enhanced 4K is also 3,840 by 2160 pixels and offers higher bitrates than traditional 4K. These higher bitrates offer even better picture quality while reducing buffering times. The result is an overall smoother, ‘enhanced’ experience.
Watching 4K and Enhanced 4K content with Xfinity TV
4K HDR set top boxes are available for X1 (XG1v4 or Xi6) (you must also have a 4K television and 4K-capable HDMI cord to watch 4K programming). Xi6 and XG1v4 set top boxes as well as the Stream app all support enhanced 4K with Dolby Atmos. Xi6 devices also support Dolby Vision.
You can use your Xfinity Voice Remote to say "4K" (or search "4K") to be taken to a 4K UHD landing page that displays all 4K programming available. With enhanced 4K, you get a next generation viewing experience of the Olympic and Paralympic Games. Feel like you’re there with our highest picture quality and immersive audio. During the 2024 Olympics Paris games from July 24 to August 11, over 400 hours of enhanced 4K content across 28 sports will be available, including a 24/7 live channel from USA Network, which will feature Dolby Atmos spatial audio.
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.
