How to Convert an HD-Ready TV to HD

Updated March 16, 2017

You have purchased a high-definition television, but now what? Simply plugging the HDTV into regular cable and using basic audio-video cables will not provide you with the crystal-clear, sharp details of a high definition broadcast. You will need additional components that do not come with the HDTV itself.

To get high-definition TV, you have to subscribe to your cable or satellite provider's high-definition cable package. This will allow you to access the HD signal source that broadcasts channels in HD. Your cable or satellite provider will then give you an HD signal box that will carry the HD signals.

Next, you have to purchase an HDMI cable. This is a special type of cable that receives the HD signal from your cable provider and displays it on your HDTV. HDMI cables are available at retail stores that sell electronics and over the Internet at web stores that sell electronic components. They come in various lengths, so measure the length necessary to get from the HD signal box to your HDTV.

Connect the HDMI cable to the HD signal box and to your HDTV. The HDMI cable has two ends that look similar to the ends on a cellphone charger or a USB device. Simply connect both ends of the HDMI cable, one into the HD signal box and the other into the HDTV.

Find the channels that broadcast HD. HD channels use separate channels than the regular broadcast. For instance, if FOX Television generally broadcasts on Channel 8, the HD FOX Broadcast might be found on channel 8-1. You will have to refer to your local area's television channel guide to find the specific channels.
