Consumers tend to buy a new set every seven years or so, and television manufacturers are hoping the technology will give consumers a reason to upgrade.
TV makers are also making their sets smarter. New TVs from Samsung, for instance, will recognise an expanded range of gestures so people can swipe through on-screen menus in a way that revolutionises the remote control. Ultra-HD sets come as small as new models from LG and Sony, which stretch 55 inches diagonally. And estimated prices are dropping from the tens of thousands to below $10,000, bringing these within the spending range.
