If you look closely, Trevor and I installed DVI connectors in Soundhouse A (SHA) and SHB. The second DVI output of the Mac goes to a DVI distribution amplifier. From there the video is split to go out to the LCD display in studio 1 and the two DVI connectors in SHA and SHB.
What’s the big deal, right? This allows anything displayed on the secondary monitor in the control room to also be broadcast to the soundhouses. One good application would be for audio post production. Put the Pro Tools movie window on the secondary display and now the musicians can follow along in the soundhouse as the music is scored to picture. Or actors can do dialog replacement. Or foley can be recorded to picture. Or, …you get it. Just don’t plug in a DVI display while the computer is running.
Our only trouble with the installation was being careful not to get the high resolution DVI cable stuck in the conduit. The DVI connector barely fit inside the 2 inch rigid conduit. Trevor gently pulled while I feed the cable into the conduit. When we hit a snag, I would pull back the cable a little, gently twist it and Trevor would continue the pull. For the record, the picture below is Trevor pulling cat5 cable for a USB extension system in studio 1. We pulled the DVI cables later that day.
