Manufacturers continue to add new content to their offerings, keeping customers current through firmware updates, and making a bit of research a prudent step in your buying decision.

3D Technology Checklist

This product is 3D-related. To help you get a great 3D experience, use the checklist below to ensure you have everything you need. 3D viewing requires:

A Display
First, you'll need a 3D-ready display--whether it's a 3D HDTV, 3D projector, or 3D computer monitor. These displays have more processing power than standard 2D models for displaying 3D images in rapid succession.
A Source
Your display may be ready for 3D playback, but you'll still need a device to read 3D content. This can be a cable box with a subscription to a 3D channel, a 3D Blu-ray Disc player, or a PlayStation 3 system.
3D Content
3D content--the actual entertainment, in other words--will be played back using the source mentioned above, whether it's a 3D broadcast from your cable provider, a 3D Blu-ray Disc, or a 3D video game.
3D Glasses
For now, the vast majority of 3D HDTVs require glasses for 3D viewing. Many use powered "active shutter" glasses, others polarized "passive" glasses. You'll need one pair per viewer, and they'll have to be compatible with your display, whether they're the same brand, or a pair of "universal" glasses designed to work across brands.
HDMI Cable
To connect your source (such as a 3D Blu-ray Disc player) to your display, you'll need a high-speed HDMI cable. Cables with this designation feature bandwidth speeds up to 10.2 Gbps (gigabits per second), for carrying the 3D signal without any loss of quality.

If you want to get more information about 3D, shop our 3D products, watch videos, or interact with other customers, we invite you to visit 3D 101, our customer center about everything 3D.

Sony KDL-55NX720 3D Viewers
Enjoy 3D action with razor-sharp detail.

Enjoy an immersive, realistic movie and gaming experience in Full HD 1080p using Sony's 3D active glasses and connecting a compatible 3D Blu-ray Disc Player or PlayStation 3 gaming console.

Sony's 3D glasses are adjustable and comfortable, designed with side panels to block out excess light that can create an annoying glare on other glasses. Better yet, they fit over prescription eyewear, and feature batteries that last up to 100 hours.

When viewed through the active shutter glasses, the on-screen image is precisely synchronized and delivered with the image intact, for an optimum 3D viewing experience. And since each frame you see is shown at Full HD resolution, the 3D action comes alive with razor-sharp detail.

In fact, from the moment you turn on the NX720, you'll notice a sharp, vibrant picture, whether you're enjoying 2D or 3D content. Sony's video processing technologies work together to deliver breathtaking picture quality with reduced visual noise, enhanced color and overall image detail, even on 1080p sources such as PlayStation 3 systems and Blu-ray Disc players.
