My monitor is connected via an analogue (or, if I'm lucky, uncompressed 
digital) link. Video signals tend to be highly compressible. Indeed, at 
higher resolutions the data may even become *easier* to compress.

But sure, I guess if you're trying to transmit stuff, there is only 
finite bandwidth to work with. You'd think all this would be less 
problematic for playback from disk though...

On the other hand, greating a succession of slightly higher resolution 
platforms gives manufacturers a way to charge you more money as you 
constantly upgrade all your equipment. :-P
