That is correct. Using the mask as reference while adjusting Brightness means that input level 16 is adjusted to produce the darkest possible black the panel can produce. It’s similar to using Hide but is easier to compare as you’re comparing the two on the same screen rather than going back and forth with Hide.I do not really understand the use of the mask to determine the minimum brightness level of the projector.
As far as I know the mask is nothing more than a surrounding area of the panels' pixels that are turned off, true or is it something else ?
The same happens when hitting Hide, where it's the complete panels that are turned off, still true ?
So will the brightness level only modify the actual remaining image area ? And what will that do to the image pixels if projecting a complete black (0 ire) image ?
