Re: KVM switch doesn't pass PnP properties

I am using a Belkin Switch2 KVM switch to share an Acer wide screen
monitor between a laptop running Vista Business and a desktop running
XP SP3. The problem is that the desktop does not recognise the
properties of the monitor so the screen resolution is not ideal. The
res I want is 1440x900 but this does not appear in the list of
possible resolutions. I have the most up-to-date drivers for the
graphics card (Nvidia GeForce4 MX 440 with AGP8X) and the monitor but
none of the possible options (default monitor, plug and play monitor,
Acer X193W) help.

If I boot up the desktop with the monitor connected directly it uses
the correct settings and gives me 1440x900 res, but this resets if,
the next time, I boot up via the switch.

Therefore I have two questions:

1. If I boot up via the switch and XP doesn't detect the PnP
properties of the monitor is there any way I can override it and
force it to make other settings available? (Bear in mind I have
tried the Desktop|Properties|Settings|Advanced and the Nvidia Control
panel and the option I want doesn't display; neither does it show
when I click the "List all modes" button).

2. If I boot up with the monitor directly connected and get the
correct PnP settings, is there any way I can make them 'sticky' so
they are not reset next time I boot up via the KVM switch?

Thanks

I don't think so. AFAIK: This is one of those setups that insists on
seeing the monitor at boot in order to set it up, so if it's not there
things don't get set up properly. I have nVidia too but likely older
than yours so if it's not among the Advanced possibilities it's likely
somethign you'll have to put up with. Check the driver possibilities
and see if an update helps, but my feeling is it won't.
It must have to do with monitor type because it's not a problem here,
but ... I do have a smaller LCD monitor where it is a problem; thus
video card & monitor drivers are a distinct possibility.

Maybe someone else has an idea. For now, just make sure the KVM switch
is on the right one to start up, I guess.
