I'll try this and see what happens.  I was previously trying to boot
whatever was on the system (possibly nothing!).

Hmmm..  could be.  Here's the model numbers:

Monitor: 98752A
Working HP's video: 98550A
New HP's video: 98545A

Aside from this, they look like they've got the same thing.

Thanks for the tip.  I dunno the model yet because I can't get it up an
telling me.  It just says "300" on the case.

See above.

Okay, I'll try that too!  ;-)

I've heard that the monitors are different freq, then the same, and
different resolutions, and even parity, and no parity - so I guess I'll
ahve plenty of variables to play with!  ;-)

Thank you all sincerely for the help you've given.  I appreciate it!

I'll let you know what turns up.  I think I'll try swapping the video
boards and trying to see if the other card will do it.  If this is a bad
idea, let me know quick!  ;-)
