I have a question about setting the black level while using Avia. The screen the you use to set black level has moving bars. Now, I realize that you don't want to be able to see the bar on the left; and you want to barely see the bar on the right. I can see "moving" of the bar on the right very faintly; but if I look at it straight on, I can't see it. So, my question is, do I set my black level to the point where I can actually SEE the bar or where I can only "sense" it moving because it's so very faint? I am a perfectionist and was curious.
