No real advice on the office, But I know more about KVM switches and video (monitor) cables than I ever wanted to. I finally got my dual monitor, two computer, single mouse keyboard, and single headset working yesterday.

I went with the iogear gcs1642 kvmp switch. Display port doesn’t play well for dual monitors, so I had to abandon my docking station and use the dsub and hdmi out ports on the laptop itself. You need a powered converter box if you want to go from vga to dvi, and it wasn’t worth it to me just to keep the dock. But display port and dvi wouldn’t work side by side. Maybe Onboard intel graphics cards are garbage, maybe it’s a limitation of the display port, I didn’t check because it didn’t matter in the end. But it runs both the dsub and hdmi ports with no issues.

Hdmi to dvi, dvi to hdmi, and dsub to dvi adapters all work just fine.
