Some new monitors do this. My 27" Benq is the same story. It is interesting, that sometimes it displays ok (especially if I power up the monitor when the O2 is already running). After restart it is green again. SGI Visual Workstation 320 has the same issue but only in PROM (Windows starts ok). Octane2 with a 13W3-VGA cable do the same but you can fix it with the "crt_option" variable in PROM.

I have four monitors and two (newer ones) do this. Older LCD monitors are ok.
