I have a Hanns-G 22in monitor that I'm trying to connect to my new Macbook Pro. There's a DVI cable connected from the monitor to the macbook pro with a little converter cable. I've tried what seems like every iteration of sleeping, turning off, and turning on both the laptop and the monitor to no avail. The monitor always remains black as if it's connected to nothing. I know the monitor is good, too, as I use it for my PC on a daily basis. I'm a new mac user and I'm not sure how to troubleshoot a problem like this.
