There's not any on the market designed for car use.
You could potentially output to a hi-def TV using DVI, however.
I see an optional single/dual DVI card offered on the Streetdeck. What I don't see anywhere are DVI monitors? Anyone aware of such a critter. I did a search and didn't come up with much except an inquiry by me ... several months ago. Thanks for any info/leads.
Or you could just use a DVI to VGA adapter and use a standard monitor...
Here's my setup, check it out.
Theres none out that I know of yet. Xenarc is making one and had a prototype at SEMA so I would think it should be coming out soon, youll have to contact them directly for details on that though.
