Hi, I'm trying to connect my white MacBook to a Dell 30" U3011 display with 2560x1600 resolution using a Mini DisplayPort to DisplayPort adaptor, as the Dell monitor comes with a normal DisplayPort and cable. However it doesn't seem to work, the Dell monitor screen remains blank after connecting it to MB this way. I pressed the "Detect Displays" button in the OSX Display Preference and it doesn't detect any external display. Does using Mini DisplayPort to DisplayPort adaptor works at all, on a 30" display? If not, which of the following options would work (with the native resolution): 1. Mini DisplayPort to HDMI cable? 2. Mini DisplayPort to Dual-Link DVI Adapter?
