iR we don't need to do nothing more that this :

edit :

/Library/Preferences/SystemConfiguration/com.apple.Boot.plist

with :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Kernel</key>
<string>mach_kernel</string>
<key>Kernel Flags</key>
<string></string>
<key>Boot Graphics</key>
<string>Yes</string>
<key>Graphics Mode</key>
<string>1920x1080x32</string>
</dict>
</plist>

Make sure you run ARD and Remote access , or what I suggest is to make a nice clean new OSX installation in one of your zilion HD and try that .

I'm pretty sure it going to work .
