Then the handshake should be taking place. Does the AE900 have the ability to switch to video/PC levels as an option? If so, try switching and whichever gives the darkest blacks is probably the correct setting. Hopefully HD DVE will be released shortly which will help clear these issues up.

I use an Accupel HD test pattern generator and the Lumagen internal patterns to do my setup, using (I'd need to verify) video levels from the XA1 and PC levels to the projector with the Lumagen handling the conversion.
