Default [Q] HDMI out while in Car Mode to Screen?

So it sounds like lots of us use car mounts and such for navigation, music, etc. I purchased REAL HDMI which allows for full (true) HDMI out to an external device, just wondering if anyone has found a car screen (touch or non, preferrably >7-10") for movies and vids and such? I just started researching screens (without the deck as it's not necessary, my device is my player) and not finding any with HDMI inputs.

Anyone else ever thought of this or have any suggestions? Thanks in advance.
