If the picture does not fit the TV screen the way you like, then you can change the Aspect Ratio.  

This procedure works for the model 8010HD and 8300HD cable boxes.

Notes: 

• Black bars on either side of the picture are caused when a TV show is broadcast in standard definition 4x3 format but displayed on a widescreen 16x9 HDTV. 
• Black bars on the top and bottom of the picture are caused when the content provider, such as Showtime or HBO, transmits a 16x9 widescreen theater movie to a standard definition 4x3 TV so that the entire width of the picture is visible. 
• In either case, you can stretch and zoom the picture to fill the entire screen. Note that stretching and zooming will cut off some of the picture or make actors suddenly look stretched sideways. Depending on the show, you may want to watch it stretched and zoomed, or leave it with black bars
