I was perusing the latest offerings of glossy mailbox stuffing in my 3' x 5' single-seat reading room earlier today, and it seems like everybody is suddenly gung-ho to sell "Quad HD" TV sets, in frighteningly large screen sizes, for around 1/4 the price a "name" brand 40" Plasma cost 8 or so years ago.
So, what exactly do you DO with the bloody things, as in: "What do you do that you can't do equally well with your existing vin ordinaire 1920 x 1080 model?"
If it was a really huge screen (80 - 100 inches or so), well, yes, the finer pixel pitch would be some advantage if you insisted on sitting close up to the screen, but other that, where are you going to get video with anything like that resolution?
The only thing I can think of is a high-end video card in a recent model computer, but the only thing that could really show is "4K" stills. There are supposedly stills cameras that shoot "4K video", but if they're anything like most of the "Full HD" models I've seen, what you will invariably get is 2K or less in a 4K container.
I notice that every one of the ads has a little disclaimer pointing out that at present, there are no "UDTV" broadcasts, either over the air or on Australian cable....
Onto another page they have their budget model DVD players, with the note to the effect that: "If you only have an old CRT TV, these are the models for you...."
Quite a few people simply refuse to believe that anybody watches CRT TVs any more. Actually, for a sizable part of the Western World's population, Digital TV never really happened, they've been on PAL/NTSC via cable for many years, and a lot of them still are.
