Let's just say it's going to involve a LOT of breaking things apart and putting them together and they'll never look the same again as a whole if i had to run another cable thru.
USB: What is this for? If it's just to hook the projector to a computer to do some settings, etc, then i don't need a concealed USB, i just hook up a USB whenever i need to use it or take the projector down.
CAT6: I have cat6 run to the control center where all the players, receivers, etc are located. Do i need one to the projector? All the processing are done at the 'media player' if i wanted to watch YouTube for instance, and then goes into my receiver, which then outputs via a HDMI to the projector. So, am I missing something here?
12V triggers: I intend to unplug the projector when not in use (for fear of lightning and power surge which happens a lot in my country as our grid is not protected).
USB is usually for f/w update.
CAT6 can be for f/w update or for remote control. For example, iRule uses CAT6 to control many devices and displays including most JVC and SONY PJs. MyMovies controls JVC projectors and might control SONY ones at some point.
12V is to trigger external devices automatically, for example an electric screen or curtains or back out blinds, so that these unfold/fold automatically as you switch the PJ on or off.
Thing is you never know what your next model might need, so it's a good idea to run them all just in case while the ceiling is open, especially if you can't run a duct (or a conduit as Mike likes to call them
) for easy upgrade. Make sure you test the HDMI cable with the projector at the length you're going to need, and that it's certified for 18Gbs. The Sony won't need that bandwidth as it's got a limited 10.2 GB/s HDMI 2.0 level B interface, but whatever you replace it with in a few years will need at least full HDMI 2.0 level A bandwidth (18Gb/s). We'll probably be using HDMI 2.x by then, but the bandwidth requirements are likely to stay the same for a while.
You might also want to run an HDMI cable with Ethernet as it's possible future displays will support this (it hasn't really caught yet).
