I have an IMAC 2.8 ghz intel core 2 duo computer and a Sanyo PLV Z60 Projector. The images on the projector are very dark no matter what I do. I run Mini DVI out to DVI and then DVI to HDMI into the projector. I have an IMAC G5 that runs to the same projector through VGA input and the images look great. Any help would be appreciated. Chris
