Force Vista (and XP) to start at a fixed resolution?

[NeilF]

I have two machines which share a KVM switch (ie: keyboard, mouse & monitor). The annoying thing is if I boot the machine to Window loggon without the monitor switched to it, then its resolution is kaka and the easiest thing to do is to reboot the machine so it detects the monitor.

Is there a way with Vista and/or XP to force them to start at a certain resolution etc? (even if no monitor is attached)

I would also like to know, my HTPC will not default to 1080p when it comes out of sleep.
