Your projector is HD Ready. Its native resolution supports a pixel-perfect display of 720p source
content. However, because the projector compresses 1080i source content to fit its native
resolution, it doesn’t support a pixel-perfect display of 1080i source content.
Video system signal compatibility
The following tables list the projector’s video system signal compatibility, particularly for signals
delivered over S-Video and Composite video connectors, which you can adjust by using the aspect
ratio commands described in Adjusting projector settings on page 14.
