I followed the tonymacx86 guide [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] ATI-5xxx3,XFX ref.model.,10.6.4, graphics update.

All ports send video,(2dvi,HDMI,DP) I can get dual monitor support any way (ports wise) but cannot connect 3 monitors simultaneously.

I have 2 dell u2410's and a 50"720p Panasonic plasma, dual display will work either 2 dell's or 1 dell and plasma.

When i have all 3 monitors connected and click detect displays the 2 24" dells (DVI) try and detect every minute or so,and the 50"720p display does nothing.I do not have another cpu monitor or smaller display to try as of now.

HDMI does not send audio and i cant figure it out must need additional kext or something?
