I always hear mixed opinions about what is noticable in regards to contrast/blacks on different JVCs.
For example, I was told if the iris is close to being maximally opened (which it is on my RS4810 at -3 for scope content as I use the zoom method for CIH with just under 700 hours on lamp) there would not be much of a difference compared to other JVC projectors at that same or relative level of opening/light output with the manual iris. But, if you're able to close down the iris (because of a smaller image, throw, etc) then the difference does become more noticable.
As I mentioned earlier in this thread or another, my calibrator Chad B measured something like 78,000:1 with the iris largely opened on a X700 vs 48,000:1 on the 4910. My RS4810 was about 46,000:1 although I don't recall exactly where he had the iris at. I'll be having him out for a re-cal tune-up probably in a couple of months and will see where it's at exactly.
