Support XFINITY TV Turning Closed Captioning On or Off


Learn how to turn on and off the closed caption (CC) feature online or on your TV.

Closed Caption Availability by Equipment

Turning on the closed caption feature depends on what kind of cable box and TV you have. We've outlined a few of the different setups to help point you in the right direction if you get Comcast service.
Note: Audio connections are not shown in the illustrations below.

Without using a cable box:

You’ll use the closed captioning features built into your TV. They have nothing to do with your cable service.

With Standard Definition or DTA:

You’ll need to use the closed captioning features built into your TV. It is likely that the standard definition cable box or Digital Adapter is unable to send and receive closed captioning.

On Standard Definition TV with High Definition or High Definition DVR:

You can use either the cable box or the TV to turn closed captioning on or off. If you accidentally turn closed captioning on in both, you’ll see a double layer of captions.

On High Definition or High Definition DVR:

You’ll need to use the cable box. Closed captioning should be turned off in your TV to avoid the chance of double layers of captions.

With a CableCARD:
