How can I use the HDMI out on my HTC EVO 3D on an external touch screen?

[AC Question]

HTC EVO 3D external touch screen

Hey guys, im looking to convert my HTC into a headunit for my sisters car-

of course i am able to power the phone and hard wire it into the car, however i would like to minimize how much of the phone i pull apart.

i am aware this unit has a HDMI out via the micro usd, but can it be used on an external touch screen? (and have the touch respond)


thanks guys
