I use Back-To-My-Mac to log into my office computer from home and vice versa. Normally, after I log into my home laptop, I darken the screen for both energy efficiency and privacy and that works fine. However, when I log into my iMac at work, I noticed the next day that the screen-darkening trick is virtually pointless as far as privacy is concerned (I share an office). The lowest brightness setting of the screen on my iMac is nowhere near a level that would prevent others from watching me work.
Is there a way to darken or hide the display on an iMac when logged in remotely? I've been searching for a solution and cannot find one.
