I'm looking at upgrading the projector in our lecture theatre to fully make use of the rather nice HD amp we have in there now.

We currently have a 4000 lumens Sanyo PLC-XU110 with a 1.65-1.95:1 lens. I am looking for something which will be native widescreen, have HDMI as well as the usual inputs (VGA/DVI, composite and S-Video?), and be at least as bright. Something with a serial control port for AMX would be good too.

Any recommendations?

I suppose we could route any SD composite video via HDMI too if those connections are unavailable.
