If people are considering purchasing an HDTV then they should really take the model’s contrast ratio into consideration. The contrast ratio along with screen resolution, have a major effect on the overall picture. A high contrast ratio is desired since these models produce fantastic colors that most accurately reflect “real world” conditions.

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 product tests, there is not a standard procedure for measuring the contrast ratio. Each manufacturer determines their own method to measure the ratio which makes it almost impossible to compare different models. However, ANSI (American National Standards Institute) has developed a test using a checkerboard panel to measure both the white and black simultaneously. The conditions of the room will play a role in the results of the ANSI test, but many companies now use this method to test the contrast ratio.

Another test used in measuring contrast ratio in HDTV is called the “full on full off method” which measures the ratio between a pure black and pure white screen. Furthermore, the test will produce a higher contrast ratio but is not a good representation of realistic 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.

It is important to remember that the contrast ratio does not affect how well motion is rendered or displayed. HDTV delivers a quality picture so it is important to select a television with a good contrast ratio and resolution. Moreover, one should not waste the features of HDTV by using an old television with a poor contrast.

If a person loves the experience of HDTV and HD movies then a television with a high contrast ratio is the model to buy. No matter what type of television, whether it is plasma, LCD or LED, the screen resolution should always be taken into consideration. In the end, one should factor in all of their wants and needs before purchasing a television.
