Here are a couple tips for in the White Lab:
-When using the computer that uses the projector, make sure that you boot the computer up first without the projector plugged into the connector on the back. Once the computer is booted up, you can plug it in and leave it plugged in.
-If a computer gives an error across the top of the screen saying there isn't a desktop source available, just click the 'Close' button on the error and double click on the big computer monitor that says 'White Lab' below it.
-When you power on a computer, it will come up with a black screen by default. This is normal. Just move the mouse or press a keyboard button and you will see the log in screen.
