With the recent release of a plethora of 3-dimensional feature films, the desire for 3D televisions in the home has risen dramatically. If you have seen films like Disney's Up or James Cameron's Avatar with special RealD glasses, you know that 3D can make one's viewing experience much more enjoyable. In fact, Avator has been critically acclaimed to have the best visuals of any film, ever (thanks in large part to its use of 3-D).
The problem is, although people want 3D in their homes, many people don't want to dish out the money for a new, "3D-ready" LCD display. So, the concept of buying a 3D TV Converter has been introduced to the public.
These 2D to 3D converters are surprisingly inexpensive: around $100. They have been around for a while (since as early as 2004), but have not had that much popularity. But in 2009 and early 2010, the sales of these products have shown a marked increase.
The problem is, these converters offer only cheap imitations of real 3D. They don't actually make anything 3-dimensional. Rather, these converters just split the image on your TV into 2 images, then uses polarized lenses to make the image on your display "pop out". However, the converters add no depth to the image.
On real 3-D ready televisions, the background of videos look like they are flush with the TV screen, while objects on the foreground pop out. The difference between the background and the foreground is what makes watching 3D movies enjoyable. Without depth, you are just watching the same movie, except the whole thing looks slightly enlarged.
