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 HDTV Digital Receiver will cycle to the next available aspect ratio choice.

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 (4:3 Monitor receiving 16:9 source signal)
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 HDTV Digital Receiver may, in some cases, change the aspect ratio from Zoom to Full.
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.
Sidebar Aspect
4:3 pictures will be viewed on a wide aspect TV screen with vertical bars on both sides of the picture.
Note: See following page for illustrations of the various aspect ratios.
