Aspect Ratio Selection
The STB changes the normal aspect ratio {picture display shape) in response to the
source signal and monitor format of your TV. You can also change the aspect ratio for
your personal viewing preference. To select an aspect ratio, press the ASPECT
button on your remote control and the STB will cycle to the next available aspect ratio
choice. The following table shows the available aspect ratios.
Monitor Format
Source Signal 16:9 4:3
16:9 Full (No Scaling)
Full - Zoom - Letbox (Letterbox) -
Shrink
4:3 Full - Zoom - Sidebar - Expand Full (No Scaling)
Full Aspect
16:9 or 4:3 picture will be displayed in the center of the viewing screen at full screen
width and height.
Zoom Aspect
The picture will be expanded uniformly (width and height) to fill the viewing screen.
The picture will be cropped, either horizontally or vertically to fit the viewing screen.
The cropped portion of the original picture will be lost from view.
Note: To properly view Closed Captioning, the STB may, in some cases, change the aspect
ratio from Zoom to Full.
Letbox (Letterbox) Aspect
Video formats with aspect ratios greater than 16:9 will be displayed at the proper
width, so no video information is lost. Bars will appear above and below the picture.
Shrink Aspect
The source aspect ratio will be maintained and the picture will shrink into full view on
the screen.
Sidebar Aspect
4:3 pictures will be viewed on a wide aspect TV screen with vertical bars on both sides
of the picture.
Expand Aspect
4:3 pictures will be viewed on a wide aspect TV screen with the picture digitally
“stretched” to fill the screen.
Note: See following page for illustrations of the various aspect ratios.
