Blanking Remote Screen
If you'd like to hide the screens of the computer you're accessing so nobody can view what you're doing, you can make the physical display of the screen black by following the below instructions.
Go to the Settings → Additional Settings → Display → Select Show Black Screen.
Once it is set up, the remote machine's screen will be black and display "Maintenance."
Multiple Monitors
You can switch between your monitors by clicking on the monitor icons on the top left corner, you can view all monitors on the same screen by clicking on the first icon.
If you have multiple monitors and would like to have the remote monitors replicated onto your own monitors then you'll need to have multiple instances of Ninja open.
To open up another instance of Ninja, minimise out of the current one and click on the Screen icon again.
You can move one instance of Ninja to one monitor and the other instance to your other monitor so you should see something like the below.
Then on the top left corner of one screen you select the first monitor and then on the top left of your other screen on the other instance of Ninja you select the other monitor.
It will then look something like the below where you have one screen on one monitor and another screen on the other monitor.
You can also full screen by clicking on the icon on the top right.
Remote Printing
You can remote print by clicking on the Printer icon on the top.
Now when you go to print something you'll see the printer NinjaRemote, you may have to first find it in the printers list and then select it.
This will now print to the printer that is set as the default on your own computer.
