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. |
Internet-Ready Television
Internet-ready TVs use your broadband connection to deliver dynamic content, whether it's streaming video from Netflix, new music from Pandora, or a quick glance at today's weather forecast.
Although there is overlap, each manufacturer offers a unique bundle of free or paid services, including streaming video and music, social networking apps, online photo galleries, news and financial updates, weather info, sports scores, and a variety of other smartphone-like applications.
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.
Learn more about Internet TVs, how they work, what services are offered by different manufacturers, and exactly what you'll need to get started at our Internet TV 101 customer center.
