A little bit off topic, but still seems to fit the category.
I heard that to change the lens on a Sony 4K unit, you needed to open up the actual projector with a key that only Sony technicians are allowed to have. So, for this whole first wave of projectors that Regal is installing, they are only purchasing the Real D lens (aka 2K) The Real D lens is shooting out two 2K images, but are only required to be accurate within four pixels. So even with the 4K projector, you are getting a fuzzy 2K image.
I haven't ever seen or confirmed this for myself, but I heard it from a tech who installs the projectors.
Anybody know if this is true?
Thanks, Kevin

I wasn't told specifically why they were pulled, just that they were gone (which required me to update our Information Page for the theater, which lists screen sizes, equipt., etc.).
We had a heck of a time trying to get them to identify the 4K shows as such. We have the ability to indicate Digital Cinema shows as well as a notes field in the showtimes, where they can trumpet the fact that they had Sony 4K units, but it was inconsistent at best. That meant that people didn't know that the shows were in 4K, much less Digital Cinema, so the marketing potential of the investment was completely lost.

You can not, of course, get 4K resolution out of two 2K projectors as 4K uses FOUR TIMES the amount of pixels that 2K uses, not twice as much.
But with a 4K master, you could use two projectors to give an image of a little higher than 2K, something similar (but not quite there) to say a 2.5K image.
But in practice, it's impossible to pixel-shift two external projectors with anywhere near the necessary precision, so you end up with a blurry mix of two pixel-shift images (if at all) and all you get is pbbly lower than 2K resolving power, but you could get a nice antialiasing effect and also cover up the screen door quite effectively by using two 2K's.
So yes. No matter how you look at it, 4K=much higher resolution than LieMax for everybody in the audience except those sitting in (aproximately) the last couple of rows (say 3-5) in most theaters, which shouldn't be able to tell a difference at that distance.
