[SBE] multiviewer monitors

[Jonathan Solomon]

Dave-
Do you have a 1920x1200 computer monitor?  You can try feeding the MV that
to see if you can see the entire screen.  Or, feed the SDI output to a
broadcast monitor, again, just to confirm the output of the MV is correct.

I can't imagine your frustration at this point :)
