		 Well, it's gonna cost a lot because DisplayPort requires an active adapter to convert to DVI/HDMI (a.k.a. one that uses electronics inside the adapter to convert the signal, rather than just wires being rerouted). Some laptops/video cards are able to compensate internally and work with the cheaper passive adapters, but a lot of them don't. 
 
Make sure you check whether your laptop/video cards requires an active adapter for DisplayPort -> DVI/HDMI conversion before you buy! 
 
I bought one earlier this year from Canada Computers so I could add a third monitor to my desktop, and it cost me like $40... feels bad man.
