Belkin KVM switch w/ WinXP Pro on laptop

[Rob]

I've got three PCs in my office, so I picked up one of
these little Belkin KVM switches so that I can jump from
machine to machine, but use only one keyboard, mouse, and
monitor. My problem, though, is that my laptop (Compaq
Evo N1000V) gets confused and when I go to 1280x1024
(rather than the laptop's LCD's own 1024x768), I still
only see a physical 1024x768, but I can pan around on a
logical 1280x1024. Effectively, it shows the video just
like it would on my laptop's internal LCD that maxes out
at 1024x768. (And of course, I've Fn+4 to turn on just
the external video.) I've done some basic diagnostics:

- If I take the Belkin out of the loop and connect the
laptop directly to the monitor (a Samsung SyncMaster
170MP), it detects it fine and I see the proper
1280x1024. Everything's great. So it isn't the laptop or
the monitor. The Belkin is introducing the problem.

- When I switch to my desktops running XP/Home, they
detect the monitor and support 1280x1024 (and higher)
just fine, so it's not that the Belkin is somehow
preventing the 1280x1024 resolution.

It appears that it's a confluence of XP/Pro, my laptop,
and my Belkin switch. Are there any ways to tell Windows
to turn off that panning mode and just show the 1280x1024?

Thanks.
