Third Monitor No Longer Displays

[BigBanc]

Hi,

Successfully perform this guide (http://www.tonymacx86.com/general-help/115818-install-bootloader-extra-efi-partition.html) and It fix my issue for AMD 7970 having to boot from my integrated graphic first. Now the problem I have is that my third monitor is no longer display after applying this. Prior of this all three monitors display. Under my display setting I can see al three. I try <key>GraphicsEnabler</key> <string>No</string>

to yes and no makes no difference. any help would be appreciate

ps.. connection type Monitor 1, mini DP, monitor 2 mini DP, monitor 3 HDMI.
