Hi all
using 10.6.2 with evo kext i'm able to load up a Mirror display on DUAL monitors with the ATI 4870 1gb card, which has 1dvi, 1hdmi and 1vga.
booting up from a vga connected and dvi2vga connected both displays come on but they are mirrior'ed.

does anyone know how i can turn off mirror and have this expanded to use dual monitor support??
or
is there a way to make videocards that has 1dvi,1vga,1hdmi to work with dual monitor?

here is my card settings/info:

Why you use a kext and not pcefi+chameleon and graphicsenabler=yes ?
This is the best way for graphic injection!
