I'm trying to make my host monitor black when I control it remotely. I followed these steps in my viewer software: Connection/Properties/remote screen/additional properties/ and I ticked the blank the host's screen. But it doesn't make it black and everybody can see my host monitor when I control it by viewer in another PC.
Could you please clarify if you have the Monitor Driver installed on the remote Host machine? It's required to be installed in order for the Blank the Host's screen feature to work properly.
If you're not sure about the monitor driver, you can double-check if the driver is displayed in the Windows device list:
If the driver is not installed on the remote Host machine yet, you can install it performing the following: 1. Open Settings for Host and navigate to the Driver tab. 2. Select Install: 3. Restart Host. You can install the monitor driver during the Host installation as well by selecting the corresponding checkbox on the Installations Options step:
