I currently have a desktop computer that I've got two 22" monitors (1680x1050) running on. I'm in the market to get a new machine, and I would like it to be a laptop so I can pick up and go any time or when I'm home, be able to hook it up to my two monitors and be able to run them as extensions to my desktop.
I've been out shopping and everyone is telling me that a laptop can't do that. One salesperson was telling me of a possible device that I could plug two monitors into so that when the laptop is connected to it the laptop would see it as one wide monitor. Does such a device exist? If so, can I get some direction as to where I can look online to aquire one?
At that point I would also need to have laptop with a powerful enough video card to support such a large monitor as would be produced by merging the two 22" monitors together into one. I would also appreciate some pointers as to what kind of laptop that would need to be and where I could find one.
