I'm curious about your last paragraph though. Unless the 5 BNC connector "RGB2" on my monitors can accept signals other than RGB/HV it would be neccessary to send a dedicated cable for each signal type. For instance monitor #1 would need cables for RGB/HV, composite, and S-Video if I want to use those signal types on the monitor. That's 3 different cables for each monitor, multiplied by 4 monitors, would be a minimum of 12 separate lines going from the Crosspoint to my monitors. Or am I missing something major that I'm going to feel dumb about?
You connections look like this (per the XM29 plus manual), right?
So since I've never owned a NEC before, I don't even know how (or if) your monitor even takes RGBS natively (manual says crap at first glance...and it doesn’t take Component either?), or if your NEC does take RGBS, if that’s ONLY through the "RGB2" connector… Or is the "RGB1" another input as well? or is that just a "throughput" like it's labeled (which I guess means output?).
Anyway, the same principles should hold true no matter what. What I've tried on other Sony, Ikegami, Panasonic, and JVC monitors is their RGBS outputs seem to be simple pass-throughs of what you feed into the inputs. You can tell this because when they're turned off they still pass that signal through, so it's definitely not being processed in any way and *should* output whatever it's fed no matter what. YMMV of course, but this is how it works on many other monitors I’ve tried.
So during normal operation (for example) your tell your Crosspoint to take a RGBS signal and throw it to Output 1 which is plugged into your NEC’s RGBS input -- and you'll get RGBS on the monitor (pretend this works as I don’t know exactly how you setup things with a NEC).
Now to get S-Video or Composite on the monitor, besides turning the monitor onto the S-Video or Composite mode, what’s to say that S-Video or Composite signal can’t travel down that SAME EXACT BNC cable you were using for RGBS? Nothing – the Crosspoint switch simply switches what you tell it to, but the problem right now is that cable is plugged into the RGBS connectors, and NOT plugged into the S-Video and Composite connectors. This is where the magic happens – and it’s stupid easy. If you run composite on the red line, simply run a short BNC cable from the Red output (of the RGBS line), to the Composite input and you have Composite running on the same cable. For S-Video – which needs 2x BNC’s (for Luma and Chroma – breakout adapters from 2x BNC’s to S-Video plug are easily available) do the same on the Green and Blue BNC output lines and plug it into the S-Video in and you’re done.
You’ll only be running one signal at a time per monitor, so as long as you turn the monitor into the correct mode before switching it on the Crosspoint, you shouldn’t even get any funkiness ever showing up on the screen….now all this is to bypass your smaller Crosspoint…which FYI my like-new Crosspoint 16x16 was $90 shipped on eBay…which would make it so you don’t have to do any of this and can run how ever many wires you want…
I'm aware of all of the capabilities of the Crosspoint, and did my research before I bought one. I would agree with you if every single one of my devices was going into my monitor's RGB2 input, that would streamline things.
