Hi, a) I have a laptop that has a DVI-DL port (and also 5 USB ports). b) I have bought 3 additional monitors to convert my laptop into a trading station. Each monitor has a DVI and a VGA connection point. Each laptop came with a VGA cable, but no DVI cables. So I need to buy the DVI cables myself. I don't really want to spend money on Matrox Triplehead2go - and not sure if that's the solution. What is the best way (e.g. configuration of DVI cables) to buy to extend the laptop screen to the 3 additional monitors (and creating 4 screens)? Thanks.
