Those are fine use-cases, but I don't see how do they need anything  
special in relation to zooming/pixel density.

It seems to me that despite large physical size, outdoor screens are not  
unusual, because due to larger viewing distance the actual perceived size  
and pixel density isn't very different from normal screens.

For example the famous display ads in Piccadilly Circus in London have  
easily noticeable pixels, so they're merely a "1x" screen, not even "2x"  
yet.
