You are not the first to find this out!!!!
The colour bars were invented for NTSC
Never The Same Colour twice!!
Anyway there are some things you can do to calibarte the monitor.
I used a LUCAS Film DVD colour calibrator found on a lot of the Star Wars discs in the other functions folders and this is effective with LCD panels.
If you have your monitor conected to an edit suit there WILL be a colour bar graphic included
Or you can seek out ALAN ROBERTS posts at the DVdoctor web site he has dowloads available for just your needs
Hope that helps - Cath
