Re: oh great - - I agree (well sort of).
I rarely watch television, so more of the same lousy programming in ultra high def will just pass me by.
However, there are several virtues to resolutions of 7680 x 4320 and higher. For starters, we're getting to the point where we can almost read a broadsheet newspaper on the screen (except the standard should also allow for an inversion to 4320 x 7680px as not everyone wants to watch widescreen movies). For all sorts of large documents: art, manuscripts, newspapers etc. this is a wonderful boon.
The other advantage of ultra high resolution screens is that it will force web creators to drastically increase the size of web page images. As it is now, web images are, in general, pathetically low resolution, over-compressed JPGs that look revolting. Super high resolution screens will put a stop to this nonsense as no none will watch the junk any longer.
For similar reasons, it will also force a rethink of the practice of lowering image resolution for copyright protection reasons. Copyright holders will now have to decide whether they want to put images on line or not.
Ultimately, cheap, lo-res cameras will go as their images will look grotty on such screens.
And finally, ultra high screen resolutions will put a stop to web editors/builders that automatically over-compress uploaded web images, hence contribute to the junk image problem. Dreamweaver for instance is one of the main culprits.
