Connecting a cable box or set-top box to your TV is a simple process you can do on your own if you switch cable providers or upgrade your TV in your home theater. You can connect your TV to a cable box using one of three different inputs: a High-Definition Multimedia Interface (HDMI) cable, coaxial cable, or Separate Video (S-Video) cable. We’ll explain these separate connections and how to set up cable for each below.


1. HDMI Cable

HDMI is the standard cable connection for most modern TVs because it displays high-quality images. This digital cable type has a single cable line for audio and video. You can find it near the standard or Type-A port on the back of most smart TVs. HDMI ports look like trapezoidal plugs compared to the more rectangular Type-A ports.

Follow the steps below to connect your cable box to your TV using an HDMI cable:
Turn off your TV and cable box.
Make sure the wall cable connects to the cable box.
Connect the HDMI cable to the cable box port.
Attach the cable’s other end to the HDMI port on the back of your TV.

2. Coaxial Cable

A coaxial cable, or coax cable, transmits a signal through a thread at the wire’s center. It provides a clear display, but the picture quality is lower than what HDMI offers. You can use these traditional TV cables with smart TVs, analog TVs, and satellite dishes.
Cable boxes and routers have a coaxial outlet; although most TVs have one, some may not. Check the instructional manual that came with your TV if you have trouble identifying the coaxial port on the back of your device.
It’s also common for a coaxial cable to connect from your wall to your cable box and an HDMI to connect from the box to the TV.

Follow the steps below to connect your cable box and TV with a coaxial cable:
Connect your cable line from your wall to the cable box.
Screw one end of the coaxial cable to the cable box outlet.
Screw the cable’s other end to the TV.
If the cable box has a separate HDMI or Type-A cable, connect that to the TV.

3. S-Video

S-Video is an older cable type you can use with an analog TV. It transmits signals through multiple threads. S-Video cables offer a higher quality picture than composite video but still provide only a standard definition quality. Some cable boxes may not have a port for an S-Video cable, but most TVs will have an S-Video outlet.

Follow these steps to connect your cable box to a TV using an S-Video cable:
Plug the cable box into the cable outlet.
Plug the S-Video cable into the cable box outlet.
Plug the other end of the cable into the TV.

Our Conclusion

You can set up cable TV through an HDMI cord, coaxial cable, or S-Video connection. Most modern TVs require an HDMI connection. This type of connection is a go-to for cable watchers because it provides a high-quality, clear picture and sound.


FAQ How To Set Up Cable

What input should my TV be on for cable?

Your cable TV input should be HDMI. This input is the most common port for modern devices.

What is a coaxial cable?

A coaxial cable connects a TV to a cable box. It transmits audio and video and can also connect to the Internet.

Why is my cable box not getting any channels?

Your cable box might not get any channels because your cables are loose or your input and output cables are reversed. Check your connections, and if tightening or switching the wires doesn’t resolve the issue, consult your cable provider’s troubleshooting guide.

Check your TV’s display feature to know its cable resolution. Resolutions are either 720p, 1080p, or 4K.
