Thank you Bruno and Greg. I'm sure that info is somewhere in the user
manual but I missed it and probably wouldn't have figured it out on my own.
If I go to a 59.94i project and set the Avid video output tool settings
to HDMI Color Space (Convert to RGB) and Output True Progressive and
crossconvert the output to 720p59.94; I can watch the same timeline
simultaneously on a Sony BVM CRT monitor (HDSDI) and the LP2480zx
(HDMI). Unfortunately, I don't have the calibration gizmo for the
DreamColor. Still, the images are much closer than I would have
expected. Quoting Montgomery Burns, "I know what I hate and, I don't
hate this". If it had a HDSDI input and accepted psf I'd probably be
gluing it to my console so that my boss couldn't move it to its intended
place. --J.B.
