What does "Image Contrast Ratio" mean?
Is Image Contrast Ratio 800:1 is good?
Answer:
what he said. to add to your question. 800:1 is not good. i reccomend 1000:1 min. don't get confused either because companies put two different types of contrast ratios in the specs: static and dynamic. static is the important one. you'll see dynamics of 10000:1 and its usually just trying to impress you with a big #.
Also, im going to go out on a limb and say that you are looking at a Vizio. Don't get it.
The contrast ratio is a metric of a display system, defined as the ratio of the luminosity of the brightest and the darkest color the system is capable of producing. High contrast ratio is a desired aspect of any display, but with the various methods of measurement for a system or its part, remarkably different values can be measured of the same subject.
Manufacturers of display devices have traditionally favoured those methods of measurement that isolate the device from the system, whereas designers of practical display systems have more often taken the effect of the room into account. An ideal room would absorb all the light reflecting from a projection screen or emitted by a CRT, and the only light seen in the room would come from the display device. With such a room, the contrast ratio of the image would be the same as the device. Real rooms reflect some of the light back to the displayed image, lowering the contrast ratio seen in the image.
Moving from a system that displays a static motionless image to a system that displays a dynamic, changing picture slightly complicates the definition of the contrast ratio, because of the need to take into account the extra temporal dimension to the measuring process. Thus the ratio of the luminosity of the brightest and the darkest color the system is capable of producing simultaneously at any instant of time is called static contrast ratio, while the ratio of the luminosity of the brightest and the darkest color the system is capable of producing over time is called dynamic contrast ratio.
