NOTE
The projector is HD-ready. Its native resolution supports a pixel-perfect display of 720p source
content. However, because the projector compresses 1080p source content to fit its native
resolution, it doesn’t support a pixel-perfect display of 1080p source content.
Video system signal compatibility
The following tables list the projectors’ video system signal compatibility, particularly for signals
delivered over Composite video connectors, which the projector adjusts automatically when you
use the aspect ratio commands described in
NOTE
The 16:9 command delivers all video modes with black bands along the top and bottom edges
of the screen. The Match Input command might deliver video modes with black bands along the
top and bottom edges of the screen, depending on the input resolution.
