I have a new mac mini os 10.6, and I've been using it with an optoma pk301 projector as a monitor. I've had trouble with the projector not detecting the computer before, but have been able to resolve it by turning on and off one or both, and unplugging/plugging in the cable. I'm using an HDMI to mini-HDMI cable. Right now, neither of them seem to be able to detect each other, and I don't know why or how to fix it. I think it started when I put the computer to sleep last night. I thought that might create less problems than letting it fall asleep by just leaving it alone as I usually do, but it seems to have worsened the situation. I've tried everything I can think of. "Detect displays" doesn't work. Any suggestions? Is there some way to view more information about the displays on the mac, get it to remember my previous minitors, or tell it directly to watch the hdmi port? The projector has a manual detection cycle which takes a few seconds as it checks all the ports, I wish there was a way to just tell it which port to use.
