OSX 'Show black screen' Issue

[christoff1992]

Hi I have been unable to remote onto my iMac whilst hiding the screen.

I have followed the steps below without success does anyone have any suggestions? or if this is a known issue with yosemite?

First Attempt:

Right Click the computer you want to edit

Click Properties

Click Advanced (lower left)

Click Drop Down under Remote Input (bottom right)

Select "Disable Remote Input and Show Black Screen"

Second Attempt:

Look at the "Actions" menu. You need to "Disable Remote Input" first, then "Show black screen" will be enabled and you can select it.
