High Definition TV

The purchase of an HDTV is a significant one and should not be taken lightly. When evaluating the overall picture of an HDTV, the contrast ratio, along with screen resolution, should both be taken into consideration. However, if a person is looking for one that offers the brightest colors and darkest blacks, then the contrast ratio should be the number one priority.

The contrast ratio is defined as a measurement of the ratio between the brightest color (white) and the darkest color (black) that a television can produce. The televisions that offer the best pictures are the ones able to produce the darkest blacks and brightest whites. In most cases, it should be noted that contrast ratio tests are performed by the manufacturer.

Unlike most tests, there is not a standard method for measuring the contrast ratio because each manufacturer has their own way of calculating it. As such, it can be difficult for consumers to compare different models with one another. On the other hand, ANSI (American National Standards Institute) developed a standard test using a checkerboard panel to measure both the white and black simultaneously, but the conditions of the room will play a role in the outcome.

Another method used to measure contrast ratio in HDTV is called the “full on full off method” and it measures the ratio between a pure black and pure white screen. The test will usually produce a higher contrast ratio but it is not a good representation of realistic viewing conditions.

The average consumer does not know what produces the sharpest colors and most would not assume that contrast ratio play such an integral part. The picture on an HDTV is made up of hundreds of thousands of tiny pixels and each of them is arranged to form complete pictures. Models with the best pictures are distinguished by their precision in separating the black pixels from nearby lighter pixels. Many companies are constantly looking to refine their technology to combat what is called “light leakage” in the industry.

Plasma TV’s generally offer the highest contrast ratios when compared to other models such as LCD’s and LED’s. In fact, some plasma TV’s feature contrast ratios as high as 1,000,000 to 1. To compete with plasma LCD and LED manufacturers now feature contrast ratios that are comparable to plasma models.

One thing to remember regarding contrast ratio is that it does not play a role in how well motion is displayed. HDTV delivers an incredibly superb picture so it is important to select a television with a good contrast ratio. After all, one should not waste the features of an HDTV by using an old television with a poor contrast.

For consumers who are regular viewers of HDTV and HD movies, then televisions with high contrast ratios will be the most logical choice for their homes. No matter what type of television, whether it is plasma, LCD or LED, the screen resolution should always be taken into consideration. By considering all the facts regarding contrast ratio and resolution, people can select the right televisions for themselves.
