To finally to begin putting non-CDS, useful interferometer diagnostics (band-limited RMS of seismic motion, glitch-grams, inspiral range [when we have one]) onto the wall monitors in the control room, I had to first learn how. Here's how you do it:

From a machine running OSX (e.g. the operator2 station on the right-hand side of the operator's workstation):
- Click on a blank space on the desktop, to switch to the "Finder" toolbar along the top.
- Either
     - Select the "Go" drop-down menu
     - Select "Connect to Server" 
   Or
     - Use the "Command + K" keystroke
- enter in the server 
   vnc://video#
   where # is a number from 0 to 6, representing each vertical pair of monitors around the room. 
This opens up a screen sharing desktop akin to what you see on the wall.

It should have all the same functionality as the OSX workstation from which you've started.
