Question: do i need a 4k hdmi cable for xbox one s?
Answer: If you have upgraded from an HDTV to 4K UHD TV, you may need to upgrade your cable as well. Getting all those 4K UHD pixels from your Xbox One S to your TV requires use of a High Speed HDMI cable. Xbox One consoles have all shipped with a High Speed HDMI cable, including Xbox One S.
