Almost everyone who watched or at least heard about the blockbuster movie hype that was Avatar would likely be aware that the 3D format is taking the entertainment world by storm.

Watching movies in three dimension is not exactly new. But with more people exposed to the technology in recent years, now TV makers are offering consumers the chance to bring that experience home.

At the recent Consumer Electronics Show in Las Vegas in January this year, 3D TVs, or TV sets capable of displaying graphics in three dimension, was all the rage.

We show you the pros and cons of getting a set:

1. You need 3D glasses

Just like at the movies, you'll need special 3D glasses to be able to experience graphics in three dimension on your TV set.

This might prove tricky especially when there are lots of people watching the same screen - simply because there won't be enough 3D glasses to go around.

Most manufacturers have said that they will include two, at most four pairs of 3D glasses with each 3D TV set. And at US$100 (about $140) a pop, extra glasses don't come cheap.

If you're planning to watch a soccer match in glorious 3D with 20 friends, make sure that everyone brings their own pair of those special glasses, or chances are you'll be forced to switch back to HD.
