TV programs can be created in a variety of aspect ratios or Screen Modes. The most common 
are 4:3 and 16:9. TVs or monitors most often have an aspect ratio of 4:3 or 16:9. 

To allow a wide variety of programs to be best displayed on the various TV and monitor 
shapes, your HD DVR features several Screen Mode settings. There are three categories of 
Screen Mode settings: HD to SD, SD to HD and HD to HD. In the case of HD to SD, when a 
high-definition broadcast is received and is then output by your HD DVR in standard-
definition format, the Screen Mode settings of Letterbox, Side Crop and Squeezed are 
available.

When high-definition content is received and output in standard-definition, the following 
Screen Mode settings are available:

Select Letterbox to view full 16:9 image within the 4:3 
output.

Select Side Crop to fill the 4:3 output. No black bars on 
the top and bottom are visible, but some of the video 
image is lost on each side.

Select Squeezed to fill the 4:3 output. No black bars on the 
top and bottom are visible, but the video image is adjusted 
so that objects may appear taller or thinner than normal.
