hello. I am having a problem of connecting my Mac Book Pro (2.4 GH Intel Core Duo / Mac OS X Version 10.5.2) to Dell 30inch monitor 3007WFP. The computer recognized the monitor and external keyboard, mouse, speaker attached to the 3007WFP works perfectly but it does not display anything. When I purchased this monitor, it worked perfectly fine, but after using 2 months, I started to have this problem and now I am not able to use this big screen. I have tried 1) turn off my Mac Book Pro and connect the DVI cable and turn on the Mac Book Pro. >> failed 2) while Mac Book Pro is on and connect DVI cable to monitor >> failed 3) while connecting Mac Book Pro to 3007WFP via DVI cable, restart the Mac. >> failed Based on looking at the system preference [DISPLAY], my Mac Book Pro clearly recognizes the 3007WFP and no matter what resolution I change, 3007WFP just don't show anything but completely black. I appreciated in advance for your support and wisdom!
