I have an acer 20" lcd and it has dvi-d, is that causing issues with the mac mini or is the logic board probably bad? it works on every other unit i plug it to. already reset pmu, and tried troubleshooting each device... cleaned out the whole mini and checked all the connections/seatings. did tdm, snow leopard's running on the hard drive. is there a way to run the efi 3s116 via firewire?
