Rats, I keep missing posts to this list for some reason.

I don't see why you are puzzled.

If a frequency above 20KHz resonates with one below, we can and will
notice that.

We do not have to be able to detect something directly to notice its
affects.

Likewise a resolution far higher than what the human eye might be able
to specifically detect can still affect the bits we *can* detect.

Again, I don't see what is puzzling about that at all.

In any case, I can refuse the idea that extra pixels don't matter very
easily:

Print technology far exceeds display capabilities, yet we certainly can
see the benefit.  We long ago passed the point where the human eye could
detect the extra pixels, but nevertheless the printouts keep getting
better.

The same will happen for display technology.

True, but that isn't what I'm talking about.

Consider a display with 10K pixels across in a 17 inch screen.  Sure, we
cannot see those pixels, but we might very well notice the color
differences made possible by the extra information.

OK, but again not what I meant.

Think about how high requencies can reinforce lower ones, or otherwise
affect the sound.

Also think about how frequencies outside our range can affect materials
nearby, inducing in them affects which we can pick up, or even feel
physically if we are present at a live show.

Just to clarify: reflective technology is quite different from generated
light technology.

Reflective "colors" in a way are everything *except* the color we see,
while with something like a display, the color we see really is what is
being generated (or generated by combinations).

Theory:

Upper management has some defect in their brains which suppresses the
autonomic system that keeps humans breathing, and they are really
suffereing from oxygen depravation rather than simple stupidity.

That would help explain how their behavior differs in being bizarre in
addition to vanilla stupidity.

Now combine low oxygen with excessive amounts of whiteboard marker
fumes...
