What you'll need

  • HDMI or component cables: See Types of Cables Used to Connect Your Set-Top Box to Your TV to learn more.
  • An HD-ready television. (Most standard TVs have 525 horizontal screen lines and a 4:3 aspect ratio. High-definition televisions have 720 or 1,080 horizontal screen lines and a 16:9 ratio. Refer to your TV manual for information regarding 1080i and 720p.)
