3 things to consider when looking for the best 3D TV

Before you go shopping for a 3D television, go into the process with some basic knowledge about 3D.

Your eyes see in 3D all the time; because of the space between your eyes, your left eye has one view of what's before you and your right eye has another view. Your brain adds the two images together to make one 3D image.

So how does 3D work with movies? Well, if you've ever taken off the glasses during a 3D movie, you noticed the movie was blurry. That's because the film is simultaneously showing each scene from two different angles in two different colors. The red and green filters on the glasses separate the two images. One of your eyes sees one image and the other eye sees the other. Then your brain adds the two together to create a 3D image. A 3D TV is a high-definition TV (HDTV) that is able to display images in three-dimensions with the help of special glasses. You have three things to consider when shopping for a TV.

Step 1: Find the best 3D TV available

If you're in the market for a 3D TV, do your research. Find side-by-side comparisons of the various types of TVs, such as the best LED 3D TV or the best plasma 3D TV. Though it might seem like a mass of unintelligible numbers, pay attention to the number of USB ports, screen size, resolution in pixels and refresh rate. Do you want to show photo lists or downloaded movies? Find out whether your laptop can be hooked into the unit. Especially with high-end ultrabooks, many of the special programs will look stunning on a 3D TV. Finally, think about what size would work best for the room in which you will watch TV. With that in mind, you can decide the importance of the other features.

Step 2: Take a cold, hard look at your budget

As with any purchase, you need to set a budget. A budget for a 3D TV should include not only the TV but also the costs that come with it, such as glasses, a Blu-ray player and discs, and any cables needed to connect the various components. The best way to get a good price is to watch for ads from stores that bundle the various items. If you don't want to set up the TV yourself, look for a sale that includes free basic installation. The best 3D TV is not necessarily the fanciest, newest model, but the one that fits best your budget.

Step 3: Decide what you will want to watch

As Hollywood makes more movies in 3D, the demand to watch them at home rises. Television manufacturers are creating 3D TVs to meet that need. Television programming has yet to keep up with the trend; you won't find very many programs in 3D, but the number is growing. Surprisingly enough, the leader in 3D TV shows are sports, thanks to ESPN. Three-dimensional television brings the action to life, which is great when watching those final seconds of the big game.
