Drivers tend to come from only two places: The equipment
maker, and the OS maker.
If you are using a conventional monitor (sold as a monitor, not a car media screen) then it plugs into the external monitor port of your computer and, if it is at all standard, the OS detects it and uses it with no fuss. (Something like 50,000 hardware
drivers ship in XP, more in Vista.)
If it is oddball hardware
...what input cable or port is it equipped with? Digital or analog input? If you can't tell, try taking it to a local high-end car stereo shop and asking them.
Touch screen is something else again, you'll need some way to put data back into the computer, a simple video connection isn't going to be two-way for the monitor.
