How to blank screen on remote computer?

I’d like to somehow set up the Vine VNC server so that when I remote in, the physical monitor is blanked/locked somehow so people can’t see what I’m doing. Is this possible?

Vine Server doesn’t support that feature at this time.
It’s a good request that we get occasionally and so we hope to add it down the road.

One idea to consider is to set up a second user account, make sure both accounts are logged in, and display the user that you are not using on the physical display. Your VNC session will not be visible.
