just bought a new mac pro. The thing goes to sleep after 30 mins and turns off my monitor. Then when I press the ESC key, the thing comes back on but doesn't turn my monitor back on. I have to get down on my knees and get behind the mac to pull the monitor cord out and put it back in a few times until it works. Monitor works fine with all other systems. Its a viewsonic 21" VP201s Considering the lack of response on this forum to my problems with this Mac so far I'm not expecting much. Any ideas? thanks and deeply appreciate any replies.
