High-definition television is crisper, clearer and brighter than regular broadcast programming. Comcast offers free HD channels to its customers. You need an HD cable box to receive the HD signal, and an HDTV to enjoy it. Connecting the two is a simple process and can be completed in a few minutes.

Step 1

Connect the coaxial cable from your wall to the "Cable In" port on the back for your Comcast HD box. Screw the cable in tightly.

Step 2

Plug one end of an HDMI cable into the back of the HD box. The cable goes into the port labeled "HDMI." Purchase an HDMI cable at any electronics store.

Step 3

Plug the other end of the HDMI cable into the back of your HDTV.

Tips & Warnings

  • Turn on your HD box and your television; your Comcast service should take a few minutes to load.
