Step 1
Start small. When trying to explain HD to someone, it will be the simplest questions that will need to be answered first in order to provide a foundation for the more complex information to follow. If the person you are speaking to is completely new to HD technology, he will probably want to know why all the HD sets are rectangular-shaped and whether that will stretch his favorite programs. It is also important to explain why the shape and form of HD TVs makes them better than regular TVs and all the different benefits of having an HD set.

Step 2
Go in to detail about picture resolution and what it means to the quality of the image. Explain how lines of contrast help sharpen picture, and give examples that reference old TVs.
-
Step 3
Explain the distinction between the different "types" of HD. Talk about the different standards for resolution, including the difference between 1080i, 1080p and 720p. Explain how the resolution can affect picture quality at various levels and how these different standards help potential buyers differentiate between sets.

Step 4
Talk about the different types of HD sets. At this stage of the conversation, your listener should know about the basics of resolution, and it is an appropriate time to talk about the difference between LCD, plasma and DLP technologies. Emphasize how, though the technology is different, the picture is still HD, and the resolution does not change. You can also bring up why some technologies are more expensive to use in an HD TV than others.

Step 5
Make sure to answer any questions. For someone who has used standard-definition TV sets, the switch to HD can be daunting, and it is important to thoroughly answer any questions he has about the new technology. Even if the question seems obvious (like "What kind of TV can I get on this thing?") make sure to answer it concisely and without insulting the intelligence of the consumer.
