>>> I have a MDD 1.45 G-4 with a nVidia gForce 4600 with a 20' newer cinema display on the DVI side and an older 20 inch Apple on the ADC side. Wen I upgraded to Leopard the newer monitor on the DVI side will all of the sudden start to get static and then go black. I turned off all energy settings and it still does it. I re-sat the card and also zapped P-ram. Nothing. Booted into Tiger and the problem goes away. ANY IDEAS?
