Letterbox (4x3)
When letterbox images are setup for a 4:3 aspect ratio screen, the black at the top and
bottom of the image are the result of the difference between the original aspect ratio
of the movie (1.85:1) and the 4:3 (1.33:1) aspect ratio of the display.

Multiple Sources

In the following example, a proportionally enlarged 4:3 image is placed to the left of
a 16:9 display, and allows the placement of three additional 4:3 sources to the right.

HDTV uses a 16:9 aspect ratio, but HDTV also requires that the signal is 1080i, or
720p. The C2N-DVP4DI accepts1080i but it must be in an RGB format, not
component format (Y, P , P

for 16:9: 1280 x 720p and 1365 x 768.

DVD Disks

Most available DVD disks are not formatted in a 16x9 aspect ratio. They are
generally 1.85 or 2.35. When viewed on a 16x9 display, they appear in a letterbox
format (although the black area is slightly smaller than the 4x3 letterbox).
To display a full screen image, the DVD disk must be formatted as HDTV (16x9
aspect ratio).
