Dual Monitor Display KVM setup for Work Laptop and Home PC

Hello all,

I was wondering what would be the best solution to my current issue. I would like to seamlessly transition via a KVM (Keyboard Video Mouse) Switch between systems.

I have a PC that has dual display via two DVI cables (Radeon 5770), and I currently have a Dell Laptop work computer that only has a VGA out. I can get a docking station that has allows for DVI output.

As the laptop from work can change and will probably be replaced every year or so, can I assume any modern laptop & docking station will have a dual monitor display output.

Or should I look at something like this:
IOGEAR External DVI Video Adapter GUC2020DW6 USB 2.0 Interface
