I recently got a Dell WFP3007; lightly used. It had previously been used on a PC and I witnessed it work. I get it home to my MacPro, it doesnt work. When you plug it in, and start up the computer, you see the grey screen, then the apple logo with the spinning gear then suddenly the monitor goes to standby mode. I replaced the dual link dvi cable with a brand new one. I took my tower into the mac store, they tested everything AND replaced the video card (ATI radeon X1900 XT 512MB, ver2) I've spent hours on the phone with apple AND with DELL also trouble shot the monitor (its fine) I was actually able to get the monitor to work ok on a dell laptop, but alas, not on my MAC. (MAC OSX 10.5.6, 2 x 3 GHz Dual-core intel xeon, 4GB 667 Mhz DDR2 FB-DIMM) I see NO REASON why this shouldn't work. WTF mate? Can someone please help me? How do I make the monitor and the computer recognize one another? this is hellish.
