I am tuned to a high-definition channel, however the picture is not displayed in full screen. What is wrong?
Not all programs are in high-definition format and therefore programs will not always be full-screen. Not every show currently broadcast by a HD station is in HD format. You can assume that if you are getting a picture on the HD channel, then your equipment is functioning properly. You may want to check your HD monitor (TV set) settings (consult the HD monitor’s user manual).
