Our Customers Say
  • I just wanted to follow up and say that I did end up purchasing this product. I've installed it and it works perfectly. I'm a bit of a skeptic, especially when competing products cost 3x as much. I'm very happy with this purchase, and I really do appreciate the input you provided to convince me to try it out. I'd be happy to give any review for this for the skeptic customer such as myself. Sincerely, Ian

HDTV resolutions

HDTV resolutions Resolution, or picture detail, is the main reason why HDTV programs look so good and that people make the investment.
Standard-definition programming most of us watch today has at most 480 visible lines of detail, where HDTV has as many as 1,080. HDTV looks great. It is sharper and clearer than regular TV especially on larger screen televisions. Remember in the past a big screen did not look so great. That is becuase you are taking the same information and spreading it out over a larger area. Standard television did not have the band width or information to fully fill up a larger screen.
HDTV actually comes in two different resolutions, called 1080i and 720p. One is not necessarily better than the other; 1080i has more lines and pixels, but 720p is a progressive-scan format that should deliver a smoother image that stays sharper during motion.
Another format is also becoming more well-known and now shipping on new products is : 1080p, which combines the superior resolution of 1080i with the progressive-scan smoothness of 720p.
True 1080p content is extremely scarce however, and none of the major networks have announced 1080p broadcasts.
