When JVC's newest contrast numbers come up each year, it's often mentioned that one only achieves those numbers by closing the iris all the way and (I think) putting the projector at long throw, which most people
aren't in a position to do.
But, and this is my question, that doesn't mean that one can't see a difference in contrast across the board given a decent contrast bump, correct? In other words, we might not be able to realize the exact highest number
JVC quotes for each new jump in contrast in a new line up, but for a given iris position one would still likely get more contrast from a newer model with higher rated native contrast than an older model.
This certainly does seem to be the case with my RS55 compared to my older RS20. It was a jump from (advertised) contrast of 50,000:1 (RS20) to 80,000:1 (RS55). While I may never have gotten a full 80,000:1 contrast out of the RS55, it's increase in contrast generally speaking seemed quite apparent compared to the RS20. I never saw the type of dynamics from my RS20 that I got with my RS55.
(Similarly, I'm thinking I might see a bit of the same advance in contrast from my upcoming RS57, even if I will never use it at it's optimal contrast settings).
