in relation to this question, I'm using the xrandr command in osx to perform operations on my external monitors. Unfortunately it does not appear to be recognising external montitors at all:

Cobrakai$xrandr  --verbose --screen 1
Invalid screen number 1 (display has 1)

Whereas it works fine for screen 0 (my native screen)

Cobrakai$xrandr  --screen 0
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 2304 x 1824, maximum 2304 x 1846

Cobrakai$

Even when other applications can tell that there are many screens (per screenshot) - how do I get xrandr to recognise the additional screens?

Turns out that at least part of the problem is that the Xrandr utility is designed only to deal with X11 windows and not native osx screens...
