Is it possible to force a Windows XP or Windows Vista machine to a resolution of 1680x1050 using a KVM switch?

[techs]

I have two separate setups that both use a single 22 inch monitor connected to two computers using a KVM switch.
The problem is unless I have the KVM set to the monitor that is booting Windows doesn't detect the monitor and scales back the resolution (interestingly to different rates with different computers).
So if I try and boot the computer that the KVM is currently set to, I may get anything from 640x480 to 800x600. I can then force it to 1680x1050 using the Catalyst control center (3 of the computers are using ATI cards). The fourth computer with onboard graphics seems capable of always remember 1400x900 whether the computer is connected or not and I can use that resolution on that computer)

So, is there any way to force the computers to boot at 1680x1050 even when it doesn't detect the monitor as hooked up because the KVM is set to the other computer?

Hmm, what KVM switch do you have? I have a cheap little USB Trendnet KVM switch connecting 3 machines to a small 15in LCD and they all get the 1024x768 resolution easily enough.

I have an iogear that is capable of very high resolutions. that doesn't seem to be the problem. It seems when windows doesn't detect a monitor hooked up on boot, it won't let the higher resolutions be loaded.

Tried going into CCC on the displays manager and click on "Force"?

I did it using these directions two months ago:

It was for the exact same issue, machines couldn't see the correct monitor capabilities through the KVM. Just set a custom res for 1680x1050 and then show all modes & you'll be set.

I will give that a try. Thanks

And, Davegod, yes I can use Force, but that's not really the problem. Even when it boots up without the monitor detected I can still just click Detect and it will change the resolution to what I want. The problem is it boots up incorrectly and scrambles my desktop and is just plain annoying to have to keep fixing.

BINGO. Solution works.
Thanks Viper GTS, this has been a major inconvenience for me and no one has been able to solve it, until you.
I bow before your geeky greatness!
