Or is 4K just easier to create and more convenient to watch?The first mainstream 3D TVs were unveiled at CES 2010, with most manufacturers displaying 3D TV demos of various types at the international expo. The film’s financial success and superb use of 3D paved the way for the 3D films that would follow, and it no doubt convinced the major TV manufactures, content creators and broadcasters that 3D TV would be equally popular in the home.Another enabling technology was the sunglasses-style polarised 3D glasses. But if 3D cinema was being phased out gradually, why was support for 3D TV ended so abruptly, and seemingly all at once?At their core, 3D TVs are the same as 2D TVs, they simply have the extra CPU power to display two full HD 1080p images at once when in 3D mode. The major advantage Active Shutter 3D TVs had over passive ‘cinema’ 3D TVs was that each eye received a Full HD 1080p image, so the resolutions of their 3D and 2D modes were the same.They had several drawbacks, however. For a start, they were often locked to specific manufactures – for example, a pair of Samsung Active Shutter glasses wouldn’t work with a Sony Active 3D TV, and vice versa. You would lose the ability to do other things while watching TV, too, like using a smartphone, or pottering around the room, as you’d need to take off the 3D glasses to interact with your surroundings effectively.For some, the hassle of this relegated 3D to being a movie night treat (along with the surround sound and popcorn,) and not something that was used regularly.3D TV always had great potential, though – and if it had been introduced a little later in the history of TV development, closer to the arrival of 4K than HD, things might have turned out different.A 4K TV is simply a TV with a resolution of 3840 x 2160 pixels (also known as Ultra HD). Another teething issue was the lack of sufficiently high-speed internet, which meant streamed 4K content was unreliable and prone to buffering – while offline 4K Blu-ray players could be costly solutions Indeed, when 4K was first unveiled some pundits predicted these problems would hinder 4K, and that the only use for so many pixels would be to perfect 3D TV.But passive 3D at 4K resolution could have been the ideal home 3D TV solution. With such easy access to 4K content, and most high-end TVs featuring 4K screens to watch it on, it was only a matter of time until 4K TVs became the new standard.But why did 4K supplant 3D TVs instead of supplementing them?Filming native 3D content requires complex and expensive camera setups, and 2D to 3D post-production conversion is time-consuming and inconsistent.
