Re: KVM switch doesn't pass PnP properties

Thanks Twayne. Just to be clear though, when I say that XP boots up
with the correct res when the monitor is "connected directly" I mean:
without the KVM switch at all. I have to roll around on the floor
under the desks and plug the monitor into the back of the PC, boot
up, then unplug the monitor and plug it into the KVM switch to be
able to use the switch as intended. :-( It's not just a matter of
the switch position while it boots. When I boot via the switch, I
always make sure that the switch is pointing to the desktop before I
turn on the computer, and leave it in that position until Windows has
started and all the preliminary stuff (checking for anti-vir updates,
etc etc) has finished.

However, it is my habit always to boot up the laptop before the
desktop (I use the laptop as my main machine now: newer and faster).
Maybe I'll try it the other way around and see if the same thing
happens.

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.

As a user of KVMs I'd appreciate hearing back what you discover.
Imagine others would be interested too.
