If you hook up a second monitor and manage to move the ccc panel to whichever is showing a good signal, then you should be able to adjust the other monitor.
You'd need to have the second(working) monitor as extended though otherwise they will try to duplicate which isn't going to work when you have an old 4:3 monitor and your newer 16:9.
Also if no driver from Sanyo, when in device manage monitors, don't search, tell it to choose from a list of installed monitor drivers and try generic or some other sanyo model.
