I frequently VNC/Logmein to my iMac from other rooms in the house and from work. I wanted to find an elegant solution for keeping the display dark while I do this, but I couldn't come across anything. As soon as you perform any task on the computer, the display comes back to life. It's a privacy issue, because I don't want my roommate or anyone else in the house looking at what I'm doing on the computer when I'm not there. So I figured that the easiest thing to do at this point is to just turn off the backlighting. But as we all know, even the lowest brightness setting on the iMac is still pretty bright. Is there a utility that will completely turn off the iMac's backlight? I was thinking that maybe I can trick OSX into somehow thinking it's a MacBook display, which would allow me to turn the backlight all the way off. Any ideas?
