Cool. Your second and third posts are great, it's just the first one you did state it "as a matter of fact".
Anyways, your right in your thinking as to what happens to the blacks when a brighter light is shining through. What your not understanding is the difference between the meaning of the word "contrast" and the meaning of "contrast ratio".
You shine a brighter bulb through the tint. It is of course brighter. Using your example, I'll try to explain my point.
Part I
Get a dark piece of tint (allows 15% of the light through). Shine a 250W bulb through it. Measure it (in theory). Now do the same thing with a piece of tint that allows 70% of the light through. Measure that. The thoretical number that is important here is the DIFFERENCE between the two measurements.
Now do the same test (in your head of course) with a 1000W bulb. The DIFFERENCE between the two pieces of tint is exactly the same with the 1000W as it is with the 250W. Sure, the dark tint looks much brighter with the 1000W, but the difference between the two is the same.
Now let's just hypothetically call the two pieces of tint in part 1 "panel A". The darker tint represents a panel's black level. The lighter tint represents the panel's white level. Lets say the difference between the two tints is 200 (made up number of course), meaning, the light tint is 200 times brighter than the dark tint, no matter how bright the light source is.
Part II
Let's try the same mental experiment with a different "panel". Panel B. This time, use a piece of tint that allows 3% of the light through (for black), and a piece of tint that allows 95% of the light through (for white). Using a 250W bulb, measure the difference between the two. You could then go ahead and measure the difference between the two using the 1000W bulb, but that would be a waste of electricity because we already know it's the same.
The difference between the dark tint and the light tint is much higher on Panel B than the differene between the two tints of Panel A. Again, the key word is difference. On Panel B, the light spot coming through the light tint is 600 times brighter than the light source coming through the dark tint. Weather it's a 4,000W Xenon, or a Bic lighter, the difference is still 600.
I hope you all now understand what contrast ratio means.
To add to that, if you want to know what happens when you raise and lower the contrast LEVEL (not contrast ratio) in your LCD's control menu, your are raising and lowering the amount of light that gets through on BOTH pieces of tint EQUALLY. Make sense?
So what happens if your picture is too bright and/or washed out looking? Lower the contrast level. Doh! But now look what you've done. Your blacks sure look black, but the picture is dim, and you can't make out dark from very dark. Your now watching "The Crow" and wondering what the heck is going on because you can't make anything out. What to do? Use a panel that has a higher contrast ratio. Then, you can raise the contrast level to get your bright image back, and your blacks are still black. And now you can make out everything in between white and black.
