Check the VGA cable (the monitor cable) that connects the laptop to the board.
Make sure the laptop is duplicating the display (sending it to both the monitor and the Promethean board):
On some laptops, you can set the display by pressing F8. On other laptops, F4. One of those keys should open the display settings as shown below. Select Duplicate.
If the board is not responding when you touch it:
Check the on/off button at the left side of the board. This button should be green. If it is red, push it.
Check the USB cable connecting the laptop to the board. Try plugging the USB cable into a different port of the laptop. (Note: this often works)
