It doesn't matter how good the display is if there's nothing to display
But neither is 4K on pay-TV, as we’ve yet to see a 4K channel appear on satellite or cable.
There is barely any Full HD 1080p broadcasts, at least in the UK. As far as I'm aware Freeview has none and Sky HD doesn't seem to do any Full HD channels, to my knowledge all the HD channels are 720p. I have a Full HD TV and the only time that gets used to its fullest is the occasional Blu Ray. Even in the World Cup, where TV tech gets pushed, there were only 3 games broadcast in 4K and none of those were available in the UK.
It's not just the price, it's pointless buying a TV that is 2 generations better than what is being broadcast, Netflix excepted. I think the TV manufacturers may have to realise that we just don't want to upgrade our TVs like we do our phones and they have overused "the next big thing in TV" to the point that the public just aren't interested in more TV technology. The marketing equivalent of crying wolf, we've had 'Widescreen', 'Digital', 'HD', 'Full HD', '3D' (people tried 3D but didn't care about that either) - most people have just got HDTV or Full HD TVs and have no intention of throwing them straight away.
