On most laptops there is a function key to use

1. only your laptop monitor,

2. only the external monitor or

3. both laptop and external monitor

It is usually a function key that makes you cycle through these options; pressing the key once makes you go from 1 to 2, 2 to 3 or 3 to 1, pressing it twice makes you go from 1 to 3, 2 to 1 or 3 to 2 etc.

Please refer to your laptop's user manual.

Another method is to use the "display" or "connect to projector" selection in the control panel.

If you have Windows seven, before connecting the projector:

1. Open up control panel

2. Search connect to a projector

3. Click the blue text saying: "Connect to a projector"

4. Select Duplicate

If you don't have Windows 7 but your provider is Microsoft then

search a bit in Control Panel
