I've just hung my HD2K projector. It will be fed by the Algolth Dragonfly scaler/processor due out in a few weeks. The Algolith HDMI Mosquito video noise reducer is due in August and I plan on using it. These two video processors will add a 300ms delay, maybe more. I'll wire as follows:

Video Chain = Source -> Mosquito -> Dragonfly -> 990 - Projector

Audio Chain = Source -> 990 w/delay
