Thanks Dotan for the reply. My KVM switch handles 1280x1024 with no apparent issues, and the video actually works great for all 3 boxes (no interference, great clarity of fonts, etc. as I switch). Just the keyboard and mouse are causing trouble. I'm using usb keyboard and mouse (wired) with those green and purple usb to ps/2 adapters on the back of the KVM switch, but removing those made no difference.
I work with some electrical engineers and they suggested a possible faulty circuit, or if a surge occurred at some point, a part of the power supply or mobo might be fused closed where it is supposed to stay open when the machine is turned off. This would cause some current to continue to be passed through the unit into the KVM switch, via the ps/2 ports in this case.
