Nothing new yet. redid the EFI string and verified it with DD's script just in case, made my own dsdt.aml, still no dice. I saw on another website that someone had this issue with their ATI video card, even though i have nvidia i tried their fix (one monitor with hdmi/dvi connector and one with dvi) still no go. Tried one monitor at a time and one card at a time also. continuing my never-ending google search for answers, this install will not beat me!

Update: I just switched from not having a signal to having a signal but no picture, baby steps, but progress!

Update: Success! Used Enabler for Nvidia from netkas and redid efi string. Registering now and will update 10.6.2 asap. Thanx for the guide xxxslayeriiixxx and for the help msf5042
