The PERFECT contrast ratio is 511:1. so when you see 500:1, is it really 511:1?
if 0 is pure black, and 1 is pure white, then you can also say 0 is pure black and any other number could represent pure white since your just scaling the value representation and not the actual color spectrum. and so, if we said that 0 is pure black, and 512 is pure white, then a perfect contrast distribution of an LCD monitor should range from 1 to 511 in two step increments, so that you get 1,3,5,7...all the way up to 511, and thus producing a perfect 256 shades of RGB values that are evenly centered within the pure black to pure white spectrum.
now this ratio is assuming that your using the maximal brightness value, since you can have a smaller brightness value, such as 1/4th the maximum value, which would transform a contrast ratio of 511:1 into a (127.75):(.25).
now im assuming that the manufactorers use these rounded off numbers, like 500:1, to make it easier to remember since consumers will not easily relate to numbers like 127:1, 255:1, or 511:1.
and so, my question is simply wether i am correct. another words, when you see a contrast ratio of 500:1 on a spec sheet of a monitor (LCD), is it really a contrast ratio of 511:1, since 500 is the closest number to 511, as opposed to 450 or 550.
and please dont ask me why it matters! i have reasons that are too complex to explain.
