Windows starting in 640x480

This may well be a hardware problem but I just thought I'd ask if
anything in Windows 2000 configuration can affect it.

I have two systems (both win2K) operating using a 2-port KVM switch. The
switch is *not* one of those where it needs to be switched to a machine
when booting that machine (in order to detect the keyboard, video and
mouse). It is perfectly happy with the switch in either position and has
been performing flawlessly for, probably, 5 years.

Recently, however, machine-A consistently sets the video to 640x480 if
the switch is in machine-B position when booting. Keyboard and mouse are
not affected and this does not happen when booting machine-B with the
switch in machine-A position (if it did, it would pretty surely point to
the switch as the culprit).

Is there anything in Windows that might affect this?

Try removing the switch and test the result.

Sorry, Dave, I don't honestly see where you're coming from with that. I
don't think there's any question that it would work normally ... as it
does *with* the switch as long as the switch has that machine selected.

I'm trying to figure out how Windows operates. It was my impression
that, having setup a specific monitor profile, video resolution,
frequency etc, Windows simply uses those settings by default on bootup
and doesn't go through any monitor detection. Yet it would seem to be
ignoring the default setup in this case ... presumably because it's
trying to detect the monitor and not succeeding.

Yet the second machine doesn't exhibit this behaviour at all.

Your suggestion has given me an idea though. It might be instructive to
swap the channels on the switch and see if the problem stays with the
machine or follows the switch-port.
