Laptop Compaq 6510 + LCD projector

You need to know what key Combinations are used to switch between the internal and external Displays for the NB, so you'll need to read the Manual for the NB here or at the very least the bit about the Keyboard controls. The Listed model [i]Compaq 6510P[/i] doesn't provide enough information to search HP's Knowledge Base as there are over 300 possible entries available so you need to be more specific like [b]Proliant 6510P[/b] or whatever the Full Model name is. You can however look here for the required details.

As for the Projector it needs to be setup correctly soyou'll need to read it's user manual as well or at the very least the bit about using the projector and what you need to do to switch it on and change the default settings or switches to push for enable it to display the Signal from your computer.
