I'm trying to get my BenQ FP91G+ monitor to work with my mac book pro. It works fine using the dvi cable in m windows xp machine. When I try to connect to my mbp using dvi, my mbp sees the monitor and I can change settings but the monitor stays black with an occasional "no input" message. I tried the same thing with another LCD monitor in the house (Princeton LCD19D) and the same problem. My monitor does work though with the mbp if I switch to using a vga cable and then use the dvi adapter that came with the laptop. Any ideas what could be wrong?
