Well, you could, but there are some complications. That panel is way too big for a car, and it probably draws 30 Watts at least so you would need to run it from a AC-DC inverter. Other than that it would probably work. I'm not sure but I think some of those Dell panels require a Dell video card as well. Most folks with digital flat panels in the car are using small ones, and some of them require a special video card.
