Black or blank screen by default for certain unattended PCs

Black or blank screen by default for certain unattended PCs

I saw this as an earlier topic but it was not finished.  I see that I can on purpose blank out a remote screen, but we need the ability to have the screen blacked out on sensitive machines by default, and not to have to rely on the remote user remembering to black out the screen when they connect.

Is it possible?
