I was wondering if we get a cable to connect our xb1's to our cable boxes? I know we get on that connects the box to the tv. Some of the unboxing videos only show one hdmi cable being provided.
You would need to use an HDMI cable included with your cable box. AT&T gave me an HDMI cable for each of my cable boxes when they installed everything in my house.
you will only get one hdmi cable.
most cable boxes will have their own hdmi cable which we can use to connect to the XB1
If you have an HD cable box, you should already have an HDMI cable going to your tv or receiver unless you're using component cables.
