www.moneysupermarket.comThe truth about 3D TV
Techno junkies just love buying the latest gizmo with the 'wow' factor and showing off to their friends and neighbours no matter what the cost. But even these enthusiasts should bear a few points in mind first before rushing to the shops, if only to avoid disappointing the kids.
For starters, 3D TVs are not TVs entirely dedicated to displaying 3D images; they're super-slim high-specification HDTVs with just another feature added on top. Thankfully, you can turn the 3D feature on and off, otherwise you'd probably end up with the mother of all headaches. But they do tend to need much higher refresh rates (240Hz compared to around 100Hz of a good quality digital TV), which effectively means you get a better picture in 2D whether or not you make the most of the 3D functionality.
Secondly, although we've moved on a long way from those naff cardboard throwaway glasses with the green and red lenses, glasses are still required to watch in 3D. And because most manufacturers have adopted 'active shutter' technology, which uses liquid crystal lenses alternatively going clear and dark to match the refresh rate of the TV screen, these glasses are not only expensive but require their own power supply, too. And many are not compatible with other makes of TV.
Thirdly, the price you pay for being one of the first people to own a 3D TV (apart from the high price) is that there is comparatively little 3D content around yet, so there won't be much to show off to your neighbours. And if you want to watch 3D movies on DVD, you'll have to fork out a fortune on a dedicated 3D player.
