Connecting your HDTV to your set-top box using HDMI

Carrying both audio and video signals, HDMI allows you to use a single cable to connect all of your components. Adam Thursby

Most set-top boxes, whether TiVo, Moxi or cable and satellite boxes, are all high-definition capable now.  If you’ve recently purchased a new HDTV to replace your older set, connecting your STB can be confusing.  In order to take full advantage of high-definition, you’ll need to change how your TV is connected.  It’s not as complicated as it seems however.  Let’s take a look at using HDMI to connect your STB to your HDTV so you can start enjoying the HD programming provided by your provider.

Since HDMI carries both audio and video signals, you’ll only need one cable to get everything to your HDTV.

Difficulty: Easy

Time Required: 5 minutes

Here's How:

  1. First, determine if your set-top box has an HDMI connection.  While most do, there are still those that providers use which, while HD-capable, will not have an HDMI out on them.  If yours does, continue reading.  If not, take a look at our article on using component cables to connect your device.
  2. Locate one of the HDMI ports on your HDTV.  Most people will use HDMI 1 as it’s easy to remember that your cable or satellite is connected to the first port.  All of the HDMI ports on an HDTV should work the same however so this is a personal choice.
  3. Switch the input on your HDTV to the HDMI port you’ve chosen.  Some won’t allow you to select the port until you’ve actually made a connection so you may have to follow the next steps first
  4. Attach one of end the HDMI cable to your HDTV and the other to your set-top box HDMI out.
  1. Be sure not to use any other connections between the STB and the HDTV.  HDMI will tend to override other connections but the opposite could be true and you won’t see anything if coax or component are used at the same time.
  2. Turn on your HDTV and STB.  If you’ve selected the correct input on the TV, you should be all set.  You can now take the time to select resolution and make any other changes needed to get the best picture.


    1. If you want to use an A/V receiver, you can do so by using two HDMI cables, connecting everything in order and again, making sure you've set your inputs correctly. An A/V receiver will allow you to take full advantage of 5.1 surround sound if the channel you're watching provides it.
