What in the world could that possibly mean???!!
Look, it's better to just admit you were wrong, rather than take the route of making a snide statement that assumes you are right and I'm wrong, but with absolutely nothing to back it up, or dispute what I wrote.
You claimed D-Cinema projectors, as used in Cinemas:
1. Produce perfect "no light on" black levels.
2. That they were superior in this way to consumer projectors, JVC in particular.
I explained why that is a false claim. Consumer projectors like the JVCs can produce far higher on/off contrast.
The most technically thorough consumer projector reviewers, Cine4Home
, provided the actual MEASURED (not just manufacturer's claimed specs) contrast of various JVC projectors:
There you can see a "low" of 26,000:1 all the way up to 130,000:1 measured on/off contrast!
Now look through the contrast specs for D-Cinema projectors, from Barco and Christie (or choose anyone else):
What do you see? Contrast numbers topping out around 2,100:1.
If you know ANYTHING about projection, you know what those numbers tell you: that the consumer projectors are capable of much higher contrast ratio. And thus if both the D-Cinema projector and the JVC projector are properly set up on their respective screens to show around 14 fL peak brightness or so, the consumer JVC projector will display significantly deeper black levels. This is not only an iron clad - and very basic! - technical fact, but the real world results are obvious to anyone who compares the black levels they can get at home with a JVC to Digital Commercial Cinema black levels which are clearly higher, more gray.
I would ask you to back up your assertions, as I have, with actual technical specs showing you are correct...but we both know you can't do that.
Here's what an intellectually honest participant would do at this point:
Admit he made a mistake - OR actually engage the above argument showing how it is technically incorrect.
Here's what a troll would do:
Respond with a vague snide comment meant to convey the impression the troll feels he is still correct, but that he feels no need to actually engage details of the argument showing he is wrong.
Which will it be, I wonder?
