Guess no one knows for sure, so I will render an opinion. My "guess" is this is suitable for movies. In a panasonic uk site they offer a DVD movie player with this screen. They probably don't in the US due to our litigous nature. I'm not familiar with Porshe, but besides them the vast majority of screens are ok for movies. Poke around the Panasonic or panasonic uk sites or give them a call then post the answer here.
