As someone who dislikes every significant DI / DD system he's seen so far, I'd love to see how the dynamic aspect on this works in person; though it would be more of an indulgence than anything else as likelihood of me being in a position to entertain buying something like this is slim.
Does it actually have any moving mechanical irises? Or is it all achieved by lamp dimming of the brighter unit? If the latter I can see some significant benefits are possible by not having to consider the dim pixels as the lamp dims (if they're already just being displayed by the dim projector).
How much control do you get of the peak brightness while still retaining dynamic contrast for SDR, for example? How does that work? As the overall peak luminance drops to SDR levels would both projectors still see much use?
If the bright projector and the dim projector lamps end up burning different amount of lamp hours (guessing) - how do you maintain calibration between the two projectors? Is there some kind of mechanism for this?
Very interesting tech that raises many questions.
