I have three computers hooked up to the same monitor via KVM switch. on a Windows 7 desktop, the monitor says "1280x1024" is acceptable but on the other two computers (both XP) it says "no signal" if I climb above 1024x768! they were all set to "1280x1024" to begin with and I had to Google how to lower it because of the issue. why can one computer be set higher than the others all of a sudden? and what do I need to do to get them back to all 1280x1024?

The monitor might support that resolution but the graphics card on the computer may not. What is the make and model of the computer.Have you tried updating the graphics driver of the XP computers?

 

There may be a driver available for XP on the monitors support site.

the graphics card can indeed support that resolution because it was initially set to that resolution and now thinks it cannot handle it after KVM switch installed

Make sure the adapter setting is set to 60HZ refresh. I am not sure this matters as the trouble began with the KVM install. Right click on the desktop, Properties > Settings > Advanced < Monitor Is the Name of the Monitor shown or only generic?

Sounds like there is an issue with how the KVM passes the video signal.  If you connect the monitor directly can you set the resolution to 1280 x 1024?
