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 of the ViewSonic Pj551 LCD Projector is 400:1.
It is referring to contrast ratio. Contrast ratio is the range from blackest black to whitest white. that said "dynamic contrast" is B.S. (a huge manipulation of the numbers). Look for "Native contrast"
mega contrast ratio is a brand name of technology used by a electronics company to describe the contrast ratio of the screen
Some of the specifications of the InFocus LP70 Plus Projector are: Data compatibility: VGA, SVGA, XGA, SXGA Aspect Ratio: 4:3, 16:9 Display Technology: DLP: 0.8" XGA DDR DMD Projector Placement: Front, Rear Contrast Ratio: 1100:1 Resolution (Native, Max): XGA (1024 x 768) SXGA (1280 x 1024)
most of the cases the resolution is important when it comes to large screens contrast ratio matters!! i mean lik the very large plasma displays!!
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 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.
This is referred to as an opaque overhead projector, or sometimes simply as an "opaque projector." This is in contrast to the regular overhead projector which must have transparencies to project, an opaque projector can project an image of opaque objects such as the paper pages of a book.
You should learn the difference between CRT, LCD, and DLP overhead projectors, and know which kind you need. Look at the portability, brightness, and contrast ratio of the projectors to find one that suits you best.
