Guys. We have posted the manual. The only way to feed it is by one of two HDMI 1.4a inpiuts. They can not be used in tandem. One can feed a 4K signal (4096 x 2160 or 3840 x 2160) that way provided the refresh or frame rate is low. In terms of a DCI type signal, the machine won't take it in. It is not DCI compliant in terms of being able to accept a DCI signal. Of course it has the resolution in terms of pixel numbers and color space of a DCI compliant machine but that of course is only part of DCI compliancy and the rest of what is minimally needed is lacking.
Sony does have DCI compliant machines but they will cost you quite a bit more for one of them.
