After decades of being a gimmick confined to midnight movies, 3D has finally hit the big time, with a slew of 3D-enhanced films streaming out of Hollywood. And it's not just an IMAX theatre spectacle; it's coming to living rooms and computer displays near you.
We look at why the technology may not be as advanced as manufacturers claim
That is, provided you can afford it. 3D video at its most sophisticated requires hardware that many people don't already have: 3D-capable TVs and the electronic glasses used with them.
3D capacity on a new high-end TV may not add that much to the base price - figure on at least £1,500 for a 46in TV - but the glasses alone can run as much as £100 per pair.
Add it up for a family of four, and you're probably spending nearly £2,000.
Getting 3D capabilities on a PC is also expensive. For example, a pair of Nvidia's 3D Vision glasses are £150, but that's only part of the cost. You also need a display that can handle 3D, which generally costs around £200 to £300 for a 22in or 23in display, and your PC must have a compatible Nvidia graphics card and be running Windows 7 or Vista.
LG and other companies are planning TVs that use the type of polarised 3D seen in movie theatres, which would allow the use of glasses that cost only a few dollars - but the sets themselves could cost anywhere from £300 upwards.
So although 3D in the home has indeed become viable, it needs to be made into more than just a gimmick to justify its premium cost.
