Probably it is a synchronisation problem. Most HP monitors are 
fixed-frequency sync-on-green, while most PC monitors have separate 
horizontal and vertical sync. The HP Xterms which I posted about in another 
message last week are sync-on-green by default, though as I discovered they 
can be reconfigured to talk to a VGA monitor by a couple of key-strokes when 
it boots (I did finally find some software for these things too, they work 
great - but HP tech support doesn't even know they ever made them!!).

If you can't find a way to blindly change the monitor settings on boot-up (or 
remotely) then you will probably need to find an HP monitor or some sort of 
`scan converter' box. Or you might be able to boot with a serial console (can 
HP boxes do that?). Good luck anyway. I'm still waiting for an HP-PA box to 
try out with Debian :-)
