You might wonder what does 1080p and 720p mean on HDTV sets. These are called image resolutions. Do they tell something about picture quality of an HDTV? Yes, but not everything. Image resolutions tell how much image detail an HDTV can display on its screen. Higher resolution means more image detail. But it doesn’t mean that 1080p is better than 720p. Their differences are noticeable if you look at near distances. Far away, well you can’t tell it. However you might find a hard time looking for 1080p HDTV which is less than 32 inches. Big TVs are expensive and the ones with more hi-tech features cost even more. Most small models use 720p. Despite such differences, there are still many buyers either of the two resolutions.
The letter “p” at the end of the number is called progressive scan. Progressive scanning is popular to HDTVs where the lines of moving images are drawn in sequence to transmit on screen. This is the opposite of interlaced video which is used by analog TVs. But interlaced videos are also used by some HDTVs. The interlaced video’s suffix is the letter “i”.
A full 1080p resolution means that an HDTV can accept a 1080p signal and displays 1080p lines as native resolution on screen. A full 720p HDTV of course has a signal of 720p. Hence, it is obvious that 1080p can produce better picture quality than 720p. But TV manufacturers don’t make all their units display only with 1080p, as stated earlier.
