This product is 3D-related. To help you get a great 3D experience, use our checklist below to ensure that you have everything you need. If you have any questions or want to learn more about 3D, we invite you to visit 3D 101--our center for everything 3D. To get started with 3D, please ensure that you have:
![]() | ![]() | A DisplayThe first--and most important--item you'll need is a 3D-ready display--whether it be a 3D HDTV, 3D projector, or 3D computer monitor. These displays usually have a higher processing power than older models as they need to display one image for each eye to create a 3D effect. |
| | ||
![]() | ![]() | A SourceWhile your display is ready for 3D playback, you still need a device to read 3D content (i.e., a movie or a show). This source can be a cable box with a subscription to a 3D channel, a 3D Blu-ray Disc player, or a PlayStation 3. |
| | ||
![]() | ![]() | ContentIn order to watch 3D, you will need to get some 3D content. This 3D content will come from the source mentioned above in the form of a 3D program, movie, or game. Please ensure that your 3D movies are in the Blu-ray 3D format, as this new format will provide the best 3D experience. |
| | ||
![]() | ![]() | 3D GlassesAll 3D HDTVs on the market require Active Shutter glasses to create the 3D effect. You will need to buy one pair of glasses for each viewer. Also make sure that the Active Shutter glasses you buy are compatible with your display--for example, buy the glasses from the same brand as your 3D HDTV. |
| | ||
![]() | ![]() | HDMI CableTo connect your source (such as a 3D Blu-ray Disc player) to your display, you'll need a hgh-speed HDMI cable. Cables with this designation--with bandwidth speeds up to 10.2 Gbps (gigabits per second)--will be able to carry the 3D signal without any loss of quality. |

![]() | With standard-definition TVs, the rule used to be that viewers would feel comfortable watching a set from a distance of 3 to 6 times the screen size in inches. With HDTV, the resolution is so much better that you can sit closer to a larger TV without noticing the pixels. So with HDTVs, the rule tends to be you can sit anywhere from 1.5 to 3 times the screen size (in inches) for the best experience. If you know the size of the room you have already, where you want to sit, and where your new HDTV should go once you get it, you can figure out the size HDTV you should get.
