I doubt it : the sound is linked to the iris moving. If I pause a movie (still image) it stays quiet. Iris touching a fan when it moves ?

can mute the sound by selecting Off."
The problem with that is two fold. 1. Your Projector should not be making that noise even with Dynamic Iris on. 2. Turning it off, you lose the Dynamic Iris which this projector needs to improve contrast. They need to replace your unit.
Thank you for checking the manual, mine is in the box at the store ..
I agree with you, DI noise should be limited to the very low motor noise, and DI is definitely needed for this PJ (IMO).

I had a projector with SmartEco before. Sure it's better than nothing, but DI is indeed way better.
I spoke a few minutes ago to my vendor at Cobra ; he heard the noise on my video and agrees it's a defect, so he will try to make BenQ accept to RMA my unit.
Even if it works, it should not be that difficult to have a 2 weeks old PJ under warranty repaired ...
