 Yes, you are having sync-on-green trouble. The O2 (as with most SGI 
workstations) puts out both composite (normal) and Sync-on-Green. If your 
monitor can't handle SOG, it will use composite sync, but the SOG will cause a 
higher voltage to be present on the green-channel. because of this your screen 
will be a bit greener than normal. 

 The solution is to turn off SOG with setmon, the precise syntax is mentioned 
in the man-pages for setmon somewhere.
