In theory, a 3840x2160 monitor would do a much better job at 
displaying the 1080p video, assuming it did scan-line interpolation 
instead of simply scan-doubling.  The same is true when feeding an 
NTSC signal into a HDTV display - the cheap ones just repeat each 
line twice (or switch to a low resolution mode and show black bars 
between successive scans) while the better ones do weighted 
averaging of the incoming signal and create a pretty good fake HD 

I've actually used a 3840x2160 26" LCD (that's about 170DPI) and 
the image is so clear you can't see the individual pixels without a 
magnifying glass.  Don't plan on driving one with a single video 
card, though.  The one I was using was being driven by FOUR 
high-powered video cards.
