This screen lets you choose one of two settings, the default Standard Screen–4:3 or Wide 
Screen–16:9. If you have a normal television, you should leave this setting at the default. 
If you have a wide screen set, select “Wide Screen–16:9.” Doing this allows programs 
transmitted in a wide screen format to fill the wider screen. If you are unsure of the correct 
setting, leave it at the default Standard Screen–4:3. If this is the wrong setting for your 
television, programs in wide screen format may appear 'squashed' horizontally—people 
would seem very tall and thin.

Movies are generally made in a wider format than standard television images. Movie 
images on television deal with the difference in one of the following three ways:

. The edges of the movie are carefully edited to make it fit 

the television format. This format is unaffected by the TV Aspect Ratio setting.

. The full width of the movie image is displayed. On standard TVs, this leaves a 

black margin on the top and bottom of the image. Some wide screen TVs can eliminate the 
margins and make Letterbox fill the screen. (See the owner's manual for your wide screen 
TV.) This format is unaffected by the TV Aspect Ratio setting.

. This method allows the DVR to choose how to display the image. If TV 

Aspect Ratio is set to Wide Screen, the DVR displays a wide screen image. If TV Aspect 
Ratio is set to Standard, the DVR displays a Letterbox image.
