Hi, Buying and installing an HDTV does not mean that you will drastically improve your TV viewing. HD, as its name implies, is meant for watching content in high definition - which means that the channels that you intend to watch should also be available in HD. A number of TV channels are still not available in high definition. This effectively means that your TV stretches the SD (standard definition) images to fill its screen - resulting in a picture quality that is worse than that of your older, SD TV set. If you watch HD channels (for example Times movies), you will certainly notice the striking difference.
