If your diplaying the same video you can either use a dual display capable video card or just buy a VGA splitter, there should be no limit on how many you could split to, but each split will degrade the signal with the more you add. Do a search on
http://www.pricewatch.com for a VGA splitter. Check out
http://www.earthlcds.com for lots of lcd screens.
You just need to power the screen from the car's 12 volts to get it to work in the car.

I was also wondering if anyone knew of a larger TFT LCD Screen that will work with the carpc? I have seen the 8" but I was wanting a 12-14" LCD TFT? Or maybe some screens that are not touch screen in 12-14".
