Summary: This monitor would not connect to my iMac or my MacBook pro. I used a Cables to Go DVI-D male/male cable and a Startech MDP2DVI converter. I reset the SMC, and powered up the computer and display both ways all to no avail. The monitor would power on OK but then said no signal. I know that it is a monitor problem because I've since got an Acer monitor (S231HL) and it works fine with the same cable and converter.
