The contrast between true black and true white on the screen. The higher the contrast ratio the better. 1000:1 is better than 700:1. An advertised dynamic contrast ration is much higher than the contrast ratio, but not a true measurement of contrast. Dynamic contrast adjusts the backlighting to give the effect of an overall brighter or darker image.
Ultra dynamic contrast ratio is the difference between the darkest and brightest image a TV can have. Ultra dynamic contrast ratio is used in LCD technology and it provides a wide range of brightness and color.
contrast ratio
mega contrast ratio is a brand name of technology used by a electronics company to describe the contrast ratio of the screen
The contrast ratio is a measure of how much light the projector can pump out. A high contrast ratio is especially important for daylight use.
The contrast ratio for the Dell S2309W is 1000:1.
A 12,000:1 contrast ratio is good, but a 50,000:1 would be better.
1500:1 is the better contrast ratio
Contrast ratio isn't standardized, so manufacturers can fudge the numbers. Consider, however, a contrast ratio over 600.
The contrast ratio of the ViewSonic Pj551 LCD Projector is 400:1.
compression ratio=uncompressed image size/compressed size
The contrast ratio is a measurement of the range of brightness can display. Theoretically, the higher the number, the better the image. A high contrast ratio means that whites will be brighter and blacks will be blacker than a lower contrast ratio. It has become an important feature because early LCD and plasma screens had a very poor contrast ratio compared to the older CRT televisions. Modern displays have largely overcome the problem and ratios of 5000 : 1 or more are quite common. However, a high contrast ratio doesn't always indicate how well the screen will display dark grays and near whites. Therefore, the real test is to look at the screen to see how the image looks. A good screen will show lots of detail in dark areas and light areas. A poor one will tend to show less detail and dark areas may show up as blacks rather than a range of grays. To make it very simple, if the picture looks good, then it is good, regardless of the published performance data.
