How do you search for the perfect HDTV, you will be put up on dozens of different, that explain various types of technology, different types of display and different quality levels. A term you will need to be familiar with the screen resolution. An HDTV image consists of many small dots or "pixels" together, and the number of pixels that are used to focus the image is called a resolution. In general, the more pixels, the better, and as a HDTVhas more pixels than a normal TV that one of the things that makes it better.
There are two different levels of resolution are commonly used in modern HDTVs. The bottom is called "720p", which means that 720 rows of pixels and it is a progressive display. In a typical wide-screen HDTV, each row has 1280 pixels. The higher resolution, 1080p, means 1080 lines of pixels, usually with 1920 pixels per line.
What you may ask, is a progressive display? In aProgressive display, 30-times per second, the display shows the full picture, then deleted to make room for the next picture. The other way to show a picture, with a "built-in display. This is where the TV is moving to the even lines of the image on the screen, then the odd lines, then the even lines of the next picture, and so on. This technique has been used on a regular TV sets for decades, because it takes about half as much effort and almost looks as good as a progressive display.Now that we have better technology, but we can make all HDTV display with a progressive and bring quality to the highest level. TV shows are still broadcast as a rule, in an integrated format, because it takes less bandwidth, but a HDTV is becoming the de-interlacing "these shows in order to gradually on the screen.
If you want to get a really big HDTV, you should seriously consider 1080p resolution. Each sentence is greater than 50 inches, alower resolution will look uneasy, because you will be able to see individual pixels.
Thus, it seems that 1080p is significantly better, and 720p is not really worth considering. But there are actually some good reasons to choose 720p over 1080p:
You will only enjoy the full benefits of 1080p HDTV 1080p, if you are viewing content. Almost all TV shows are still in 720p or 1080i, so a 720p set, it will treat well.
If the screen is smaller than 50 inches, it becomes very difficult to tell the difference between 720p and 1080p. In the case of a normal viewing distance, they look basically the same.
A 1080p set will almost always more expensive than a similar set with 720p resolution built. If you do not make much difference in picture quality, why more?
If you are the big picture on your HDTV purchase, the screenResolution is only one factor. Contrast ratio, black level, the likelihood of problems, and even customer service are all more important factor than the screen resolution. Do not be an exciting feature convince you to buy at a lower.
