It has worked in the past.
The DVI cable isn't super long. The one I substituted in is 25 ft. The installed cable goes out of the rack, over the ceiling and down into the projector. Can't imagine that the installed cable is much longer.
My rationale: 1) Bypassing the Gefen, from the Blu-Ray directly to the BlackBox splitter eliminates the Gefen and its associated cables.
2) Swapping the cables on the BlackBox eliminates the BlackBox and any cables inputting signal to it. Otherwise, the problem would have moved from the live screen to the preview monitor. Swapping these cables makes no change.
3) Substituting a DVI-D cable from the BlackBox to the projector eliminates the installed cable.
4) Toggling the "auto format" setting on the projector SHOULD have made it select the correct resolution, interlacing and format by itself. Right?
I don't remember every exact setting of the projector itself. I'll have to go through the menus and check. I'm not super familiar with the menus and settings on this projector. We've only had it for a couple of months and I haven't had much call to do anything more than operate it normally.
Can somebody walk me through what the menus and settings should be?
I can't fuss with the machine right now because there is a show running. (The Dolby DSS-200 / DCP system works correctly.) I'll have to work on this, incrementally, between shows.
Next show, on the in-between, I'll substitute the DVI cable directly from the Gefen to the DVI-D input of the projector to positively eliminate the BlackBox from the list of candidates. (I don't think my HDMI>DVI-D cable is long enough to reach but, if it is, I'll try that, too.)
Didn't think of the grounding/UPS issue. I don't think all equipment is supplied from the same source. Does the auxiliary equipment need to be simply on the same ground or does it need to be all supplied from the same SOURCE. (i.e. Off the UPS?)
The UPS is in the base of the projector/server. The auxiliary equipment is in the rack. I suppose everything could be made to be on the same circuit or ground but I don't think they would be able to be powered off the USP in the projector base, 5 or 6 feet across the room.
