What is the difference between a dynamic and static contrast ratio of HDTV?

When buying a high -resolution TV (HDTV) is a significant consideration contrast ratio , for example 10000: 1 . The HDTV with a high ratio will produce more true blacks and will display more details in low -lit scenes. It should be quite easy to find a good contrast ratio, except that it is a catch. There are two types: dynamic and static. Understanding the difference will help simplify HDTV shopping. For example, some LCD HDTV use technology that brightens the overall picture in well -lit scenes to achieve very bright white, and darkens the overall image in low -lit scenes to achieve true, darker blacks. Measurement of the most pure white in a clearly lit scene compared to the darkest darkness in the low -lit scene results in a dynamic contrast specification.

The static contrast measures dark and light in a static shot or the highest contrast ratio reachable in the same scene simultaneously. This is a smaller number but measurement PRavdivě in terms of overall image quality. It is a measurement that the buyer should take into account more, perhaps than a dynamic contrast, but because the dynamic ratio is a higher number, it is often the number used on the HDTV specification card, especially if the static number is bad or average.

While the best judge of a good image remains its own two eyes, the specifications are suitable for comparing products that are not side by side (or when buying online). Many experts generally recommend a dynamic contrast ratio of at least 10,000: 1. Some HDTV ratios today acquaint 50 000: 1 or higher. However, as mentioned earlier, static ratio is more important.

Good StartBod for static contrast ratio is at least 1,000: 1. Some HDTVS specifications acquaint up to 1,500: 1, 2,500: 1 or even 5,000: 1. Remember that a high number can refer to a dynamic specification, although time brings upDrying to static specifications, so shoppers should surely check which type of ratio is advertised. For example, plasma HDTV tends to have a general contrast ratio than LCD.

knowledge of the difference between the two measurements emits the confusion of HDTV vision with a contrast ratio of 1,800: 1 (for example) and notes that it looks better than HDTV with 10,000: 1.

Whenever possible, shoppers should look at real displays before buying. If you buy online, they should first try to go to some local stores to see TV in action. Specifications help, but the eyes are a better judge of what will be pleasant.
