I have a question for those knowledgeable in screen technology (Hopefully Don Stewart).
Is the enhanced black level on the Grayhawk and Blackhawk materials really in increase in measured contrast ratio over a Studiotec 1.3? Would a light meter actually give a numerically larger ratio?
I suspect that it won't and that what we percieve as improved black level is just that - perception. Now, I have no problem with being fooled into believing I am seeing more contrast. As long as the picture looks great, I'm happy. This is just a question for my own knowledge base.
I cannot see a way for the screen to differentiate between low level signals and high level signals without being a non-linear device. It would have to reflect a higher pecentage of high level brightness than that of low level brightness in order to change the actual measured contrast level.
The only other thought I have is that the screen could be pattern dependent. High intensity light would be sent back over a smaller viewing angle than low intensity light. This would also increase the measured contrast ratio on axis. I just don't lknow if either of these are realistic possibilities.
In any event, I am just looking for a scientific answer so my brian doesn't hurt when I try to figure it out by myself. I'm perfectly happy with being fooled, and in fact, I am planning to order a Firehawk for my soon to be purchased Marantz.
