Am wanting a digital cinema projector, capable of playing DCI spec content from a media block, that is also capable to display non-DCI 4K content via outboard devices connected via DVI interface. The Sony R320 does not have that capability. To do both, I'd need two projectors, e.g. an R320 and R420. Does anyone know if, once Christie ships 4K CP2230, or Barco ships 4K DP-2000, if those boxes will support 4K via DVI interface in addition to the media files-based method for DCI spec content? Thanks!
