The Epson is out of the running, since you are talking scope screen here. The Panny will work, if you use it's brighter modes, but you are throwing out color accuracy. Art at Projector reviews got a little over 600 calibrated, best mode lumens, mid zoom and high lamp. The JVC in the same conditions will do a little under 900 lumens. When you go to dynamic mode it is reversed, the Panny has more lumens. I am not a fan of the dynamic iris in the Panny, nor do I like the screen door that can be seen when using larger screens.
I've known you a long time in these forums, I miss your more theoretical posts which I sometimes learned from. We all learned from each other, though I know nothing about audio and am a dummy there.
Maybe you watched the Panny IRIS in Cinema Mode, the projector needs to be in Rec709 mode. Switching gears, I like the Benq w7000's IRIS because you can tweak it to your heart's desire to be as aggressive or less aggressive as you want. The problem though with the Benq's IRIS is you are starting at 700:1 to 1000:1 Native On/Off, and the IRIS can only help things so much at that native on/off start.
Pretty much it's hard for a projector to have a good IRIS if the Native On/Off is below 5000:1, but, there are some that do (Sony as we know, best IRIS gotta be Runco and Sony???)
I've watched the Runco LS-5 a little (tiny bit), not long enough to make much discernment. I didn't really see many dark scenes on it, the Sony IRIS is the best I think.
I know you can't write down theory all day though because I know how that gets (I've even had to cheat a couple of times to google some theory I forgot about some lamp ballast). I'm not too proud to admit it, I know I've been controversial a few times in here, but it really was ALL IN FUN to get discussions going. I did trigger some DEEP theory discussions by being overly BRASS a few times, but someone had to do it.
I especially liked the contrast discussion, I was wrong on a couple points, but didn't care because by the end of that Deep Contrast Thread, everyone agreed on the theory of how contrast works.
I was even reading documents about how radiologists are TRAINED to identify contrast gradients. I think some of the medical contrast theory goes even deeper than the contrast theory in projectors
