Brightness will normally hover around the 60 mark if the projector is calibrated correctly.
Contrast can be anywhere between 40 and 75, and is adjusted to attain as close to just above 10FtL as possible. The variables are the newness of the tubes, the screen size and its characteristics and the room decor and lighting control.
Lots of factors to consider which just goes to show the numbers are irrelevant in a comparison discussion
This brings up a point Im starting to notice more. Video cards are not running consistent between exact cards with exact settings so use a external reference generator to check first then reset to the actual card being ran.
The internal test patterns I dont use.
I have found brightness 60-70 and contrast 50-65 from the same model cards with the same settings. Doug
