Sorry, there was a problem. Please try again later.If your x1 box has a hdmi output ,your new tv will have 1 or 2 hdmi inputs to plug into.
Sorry, there was a problem. Please try again later.There should be an hdmi port either on the side, rear or bottom of the tv. Different manufacturers have different locations. Also the other end will plug directly into your xfinity box
