Hi Everyone, I ported the Display Manager calls for switching resolution and they seem to work, however FN DMSetDisplayMode wants something called a Display State handle. Anyone know what this is? Since apple changed their website, I haven't been able to find the volume of inside mac that might have this info. Also as a side question, how do I find the current state of the monitor (for switching back) specifically the length, width and bit depth?
