That's a problem. When viewing sports and "live" shows, I turn off the iris. It's totally open allowing as much light as possible. When viewing movies, I set the iris to "auto" which allows the iris to open and close in increments depending on the brightness of the scene.
Since the iris in auto is always adjusting, it seems to be an inaccurate way of setting contrast and brightness levels. I was just wondering if there is a "right" way to calibrate auto-iris projectors or not. I'm leaning toward adjusting with the iris "off", but want to confirm this is the best way.
