I have an iMac mid 2011 at home. When I was not home, I may need to access my mac with Screen Sharing. However the iMac display will turn itself on when I connect via Screen Sharing. The problem is I don't want to scare my family at home (with the elders and kids) as the iMac "turn itself on suddenly".
This is a problem specific for iMac. On MacBooks (Pro, Air, whatever) I can set the brightness to the lowest setting so the screen is black (i.e. the LED light is off). However on an iMac you cannot turn off the LED backlit by setting brightness. The display is still bright and everything is clearly visible even on lowest brightness setting.
Therefore these solution are not working as the display will turn on as soon as you move your mouse or hit any key on the keyboard via Screen Sharing.

Question: Is the a way to keep the iMac display off while you accessing it with Screen Sharing?
I have a workaround, but that's not perfect. With Brightness Control (freeware), I can make my screen black while everything is still visible via Screen Sharing. However it didn't turn off the LED light. A black screen with the LED backlit on is still drawing enough attention in the evening.
