Your projector is HD ready. Its native resolution supports a pixel-perfect display of 720p source
content when it’s in 16:9 mode. However, because the projector compresses 1080i source content
to fit the projector's native resolution, it doesn’t support a pixel-perfect display of 1080i source
content.
Video system signal compatibility

The 16:9 on-screen display (OSD) menu setting delivers all video modes with black bands along
the top and bottom edges of the screen. The Match Input OSD setting might deliver video modes
with black bands along the top and bottom edges of the screen, depending on the input resolution.
