One of the most provocative ways to lure customers is by flaunting esoteric, technical terms in their faces and then by proving that these really matter to the customer, so that they feel the need and desire to buy that item. Some of these features and characteristics may be relevant, but mostly there is little reason for a host of factors being flaunted. For an average consumer looking to buy something, these factors can often be rather confusing and challenging, in that they make taking a decision harder than before. This could of course be avoided by being prepared when you go to buy something, because you already know what you are looking for.
The rapidly evolving world of HDTVs is no different from the issues listed above.
The factors that need to be looked into before buying a HDTV are listed below to enhance understanding.
One of the primary factors is the contrast ratio, which is listed almost universally, with all televisions. Essentially the contrast ratio delineates the maximum difference between the white and black pixels because a greater contrast ratio makes the picture look all the more realistic.
Another important factor is the response time exhibited by the television. The response time reflects the total delay required for a pixel to turn from one color to another and is generally chosen as the transition from white to black or the other way around. However, there are certain television manufacturers who rate response time by reporting time required for a pixel to turn from one shade of grey to another. The transition between greys is generally faster than the transition between black and white. However, the lack of a unified standard means independent response time criteria for each manufacturer. However, response times for most televisions are advanced enough so that little differences exist.
Refresh rate is another important criterion that is often under reported for most televisions. There are vast differences in refresh rate levels with the most timid starting somewhere around 60 Hz for commercial applications. The next standard arrives at some 120 Hz while the fastest standard lies at 240 Hz. The difference in image clarity especially for moving images is vastly different for 60 Hz and 120 Hz with the latter being superior. However, as the refresh rate is increased, there is no guarantee of better image manipulation. In fact, at some 240 Hz the image manipulation is so catalyzed that a certain violent shaking is experienced. The resolution is often too fast for extended viewing periods with a comfortable viewing experience. Therefore, it is generally most suitable to watch out for refresh rates of some 120 Hz, as they tend to produce clear and crisp images that agree well with the human vision system.
Size of a Television Screen
Lastly, the size of a television screen is probably the single most important factor of all. Most people tend to buy the largest television that their budgets can afford but often the results are rather unexpected. Depending on the overall location and viewing environment of the television, it is often the case that larger television screens produce straight lines when viewed too closely. Only the right size tends to produce the perfect image quality.
