Want to watch 4k UHD videos from the Microsoft Store?  You need to have an Xbox One S and be connected to a 4K television over HDMI 2.0a with support for HDCP 2.2. And, the device should have a 20Mbps or faster internet connection speed.

Ultra High Definition movies can be purchased by selecting the UHD option in the resolution drop down menu in the Microsoft Movies & TV Store.  A High Dynamic Range (HDR)-capable television is required to view content offered in HDR.
