There's no way to do that. These are custom cables that have 
single/special D-Sub connectors on one end that pick up the video and 
vga signals, and breakout cables on the other end for plugging into the 
connections on the computer. The strange thing is, this is a much more 
expensive KVM than the one I replaced, which worked perfectly. I was 
only trying a replacement because of a different issue I'm having with 
some strange interference between my phone and my computer wiring. (When 
I sit down at my desk, the device that picks up my handset and switches 
to my headset, picks up the handset without being asked to, and at the 
same time, the mouse and keyboard freeze on my computer - but, I digress)
