subject: Lets Take A Closer Look At High Definition Tv [print this page] After a day of hectic schedule and tiresome work, all of us look for some kind of entertainment before hitting the hay. The popular choice is watching TV. There are many interesting programs broadcast for such people. The television has evolved from analog format to digital format and then to high definition format. High Definition TV is becoming more common and many shows are available in HD programming. We all know that the picture quality of HDTV is better than digital TV. You might be thinking of upgrading to HD. Knowing more about it before buying it would be more helpful to utilize the benefits well.
Looking at the differences between standard definition TV and high definition TV will help us know why HDTV is better. The basic difference is the resolution that both offer. SDTV offers a resolution of 720x480 pixels, whereas the resolution offered by HDTV is 1280x720 pixels or 1920x1080 pixels. In simple words, HDTV offers a larger image area, making the pictures clearer and more realistic. The next difference is the refresh rate, i.e. the rate at which the screen is refreshed. SDTV refreshes 24 times per second while HDTV refreshes 60 times per second. The next difference is the aspect ratio. SDTV has an aspect ratio of 4:3, whereas HDTV has an aspect ratio of 16:9 giving it the feel of a movie screen.
The next thing to look into is the equipment needed to watch shows in HD format. Not all shows come in HD format but most service providers offer HD programming. What devices or equipment should you have to watch programs in HD format?
An HDTV set
An antenna
A cable or satellite HDTV station
There are many varieties of HDTV available in the market such as HD in tubes, LCD, DLP, Plasma, LCOS, and CRT rear projection. If you watch a show that doesnt have HD programming, it wont be great on your HDTV as the resolution will be low. Therefore, change the resolution of your monitor while watching such programs. When you want to watch a show offered in HD programming, you can change the resolution to 1280x720 pixels.
HDTV is available both in square and rectangular shapes, in technical terms, standard or widescreen formats. Though it is said that the widescreen format is better, most programming can be formatted to fit into the standard format. Therefore, you can get the same picture quality with both formats. After getting the television set installed, the next thing you will need is an antenna, cable, or satellite service. Most Satellite TV Providers provide HD programming for even non-HD channels. However, it is not the same with cable service providers. You will have to buy a set-top cable box or a card which will let your equipment decode the HD signals.
After getting all the equipment and connections ready, the next thing you have to look into is configuration. Configuring the HDTV will let you better your TV watching experience. Some of the settings you would need to adjust are black level, contrast, and color saturation. If you have opted for a HDTV-ready set, you will have to buy a HD tuner which can convert or decode the HD signals. Additionally, you will require an indoor or outdoor antenna for such sets. Unless your antenna picks up the right HD signals, you will not be able to watch shows in HD format. Therefore, use a tuner and check your monitor resolution to ensure your TV picks up the right HD signals.
Checking all these and setting the TV in the right caliber will help you have a great TV watching experience.
