What Everyone Should Know About Buying a Flatscreen 3D TV


3D movies have been a big draw at the box office, and a great money-maker for movie houses. Now, 3D has come to the home theater. Is it time for you to buy in? And if so, which 3D TV is right for you?

While 3D TVs have been around for some time, they are now making the move into the mainstream. Some feared that they would not offer 2D as well as 3D, and others simply decided that 2D was good enough for them. The memory of cheap paper glasses with different color lens will always stick with me.

Others disliked having to wear the glasses at home (it seems that it does not bother people at the theater.) However if you have ever experienced a great movie or a fast-moving sporting event in 3D, you will understand what all of the excitement is about.

Three Distinct Approaches

There are different underlying technologies used with the 3DTVs with the original technology predating television, but we will not worry about that. The basic function that a 3DTV is trying to do is to display offset images that are filtered separately to the left and right eye.

Basically the current generation falls into two categories- active 3DTVs and passive 3DTVs- and manufacturers tend to build one style or the other, although a third is starting to emerge, called Autosteroscopic or Auto 3D.

This where the glasses come in, although there is an option that does not require them. With glasses a user gets a filtered image for each eye, with the two images making up the 3D whole image. The active glasses use a liquid crystal technology that requires batteries. The passive, a bit newer, uses polarized lens. Both work just fine with accessories such as Blu-ray players and you don’t need to look on the peripherals to see what type of glasses they support.

The non-glass technology is called Auto-stereoscopic, or Auto 3D, and it is achieved by having pre-set viewing positions that users have to sit in while watching video. While there are a few sets available currently, it has not yet become a widespread commodity, possibly due to the regimented seating issue.

Which is better? Both the passive and active camps make pro claims about their products, and negative ones about rivals, yet the key issues that once differentiated the two camps appears to be going away as each generation improves image quality and a host of other issues.

So it is really the quality of the television and manufacturer that will make a major difference in the quality of the 3D image, and it is up to an individual to decide which of the technologies work best for them. I have tried both and at times loved both and disliked both, and it always boiled down to the quality of the system (and, once, defective glasses).

There are a few things to pay attention to aside from the 3D technology, screen size, refresh rate and the other details that a customer wants to command prior to buying. Look at how many pairs of glasses come with a set that needs glasses, and check on the availability of additional glasses. Just like sunglasses, someone is eventually going to sit on a pair and break them. Also, as televisions increasingly become hubs in a home for a range of digital uses consider if this is a feature that you will regret if you fail to ensure that the set you purchase does not include Internet access and other features. They often add little or nothing to the final cost and so it behooves you to look for these features as well.

Here are some good, representative models; prices and availability are accurate as of October 23, 2012. Check the 3D TV Department at Adorama for the latest deals and products.

A key technology from LG is its NetCast Entertainment Access that enables the 3DTV to connet to the Internet so that you can stream videos as well as actively browse the Internet all without needing to use a computer as an access point.

Samsung 46

The $1,697.99 Samsung 46" Class 1080p LED HDTV shows that even as screen sizes get a bit smaller it does not mean that there is any diminishing of features. This 46-inch display has built-in Wi-Fi that helps the television serve dual duty on the Internet and just as an entertainment device capable of showing top resolution videos.

It features a 240HZ Full HD 1080p, 1920 x 1080 resolution display that has features that many rivals do not offer. How about face recognition software that allows you to log into apps automatically?

Coby 32

Not all 3DTVs are destined for huge rooms to serve as the center of a major entertainment center. Maybe you are looking for something smaller, maybe for a bedroom dresser, a small apartment or for a guest room- then the Coby 32" ATSC LED Passive 3D TV  might just fit the bill. The 32-inch display has Full HD 1080p resolution and comes with three HDMI connections. Colby ships the passive system with four pairs of glasses.
