Better Picture Quality
The most notable benefit of HDTV is the dramatically improved picture quality. The usual resolution a normal TV can display is 525 scan lines with 480 actually being visible. The usual TV can display a resolution of about 210,000 pixels per image. High Definition TV's can go all the way up to 1920 (horizontal) x 1080 (vertical) pixels, with a total of 2,073,600 pixels per image. That is ten times
the resolution and picture quality of usual TV.
Better Sound Quality
HDTV's digital audio sounds better than a standard television's analogue sound,
just like digital CDs are superior to analogue radio. All HDTV programs use Dolby Digital sound, which is also used on DVDs. This format is used to transmit two
to six channels of audio depending on the program. With these soundtracks driving 6 speakers, Dolby Digital creates a home theatre experience rivaling
the best cinema sound.
Future Proofing Your Purchase
With more content becoming available in High Definition and the analogue
signal ceasing in 2010, deciding to purchase a HDTV effectively future proofs your investment.
