LED, LCD and plasma TV: 3D TV essential guide 3D-ready TVs
The big television manufacturers all have 3D TVs. We saw the first models in the shops in 2010, since then there has been a steady stream of launches.
The quality of 3D picture is highly dependent on the 3D TV
How much do 3D TVs cost?
Passive 3D TVs tend to be a little cheaper than active 3D TVs. You can find plenty of models under £500, even a few as large as 42-inches.
Although the 3D effect tends to be more enjoyable and immersive on a bigger screen, smaller screens can be fine if you are sitting near enough.
If you are viewing the TV from a distance, or from an angle, the 3D effect is likely to fade and other picture problems may materialise.

How do 3D TVs work?
3D-ready TVs polarise the original 3D pictures into separate images. They appear on screen as blurred images – but with the addition of 3D glasses, the separate images are directed to either the right or left eye, creating the impression of 3D depth.
Do I need to wear 3D glasses?
To see the 3D effect on current models, yes.
If you find wearing glasses can be uncomfortable, consider that passive 3D TVs come with glasses that are much lighter than active 3D TVs.
How many pairs of 3D glasses do I get when I buy a 3D TV?
If you buy a passive 3D TV, expect at least four pairs. LG supplies an extra pair of clip-on passive 3D glasses for spectacle wearers. In any case, passive 3D glasses cost just a few pounds each.
If you buy an active 3D TV you'll get up to two pairs usually, but sometimes none at all. Active 3D glasses are more expensive.
How about standard 2D?
All 3D TVs are happy displaying 2D pictures too, whether in standard definition or high definition.
Most also have a setting to display standard 2D TV as 3D, but our tests reveal that the 3D effect is rarely convincing or enjoyable to watch.
