In order to view the highest quality picture on your HDTV, you need High-Definition (HD) programming. You must get HD programming to get an HD picture. To view the best possible picture, you will need to upgrade your current TV service to include HD programming, if you have not already done so. An HDTV without an HD source is just an ordinary TV. There are 3 primary ways to get HD content: 1) Off-Air antenna (antenna sold separately - using the RF antenna input). To see if you are able to receive HD signals off-air and for help choosing the right antenna, visit http://www.antennaweb.org. 2) Cable - Cable customers will need to subscribe to HDTV programming from your local cable company (HD cable box required - additional monthly subscription may apply). In some cases, Networks (e.g. CBS, NBC, ABC, PBS) may be available in HD by programming the cable channels using a direct cable feed into the digital tuner. 3) Satellite - Satellite customers will need to subscribe to HDTV programming (HD satellite receiver and appropriate hardware required - additional monthly service fee may apply). Note: Digital cable or digital satellite is not necessarily HDTV. The picture quality is superior to today's analog TV signal, but most of these channels are not HDTV. You will be able to tell the difference by subscribing to HDTV programming! Contact your cable or satellite provider for further details. HDTV and today's analog television differ in resolution. HDTV uses a 1920 x 1080 pixel resolution, while analog television uses a 720 x 480 pixel resolution. This means that HDTV images are sharper and more detailed. HDTV also supports a higher frame rate, which means that images are more fluid. Additionally, HDTV supports a wider color gamut, which means that images are more vibrant. Overall, HDTV provides a better visual experience.
