Timid1 is right. Most LCDs are very easy to interface, they use standardized controllers. The monochrome graphical LCDs that size use the T6369C or the SED1330. I don't happen to have a color LCD, so I'd assume you'd need to do some research to find what the controller is. Chances are the interface is simple enough, and if not in a direct serial or parallel configuration, can easily be adapted to a non-VGA or DVI port. Hower, the really annoying stuff is the software. I have a T6369C LCD, and I was able to use it parallel, and USB, but I can only run PowerLCD on it, since very few programs are designed for graphical LCDs. I will probably try to make something for it when I get the chance since I have some programming skills. However, your situation would be even worse since it would be much harder to program in color, let alone a driver that would allow you to do something like extend your desktop.
