Can you provide me more informaiton about your laptop.

To be able to use external monitor you have to click on alt and f5 it will automatically switch off your internal lcd and activate your external lcd.

Some Monitor adaptors on NB's also display external Monitors as Extensions of the desktop so you could be seeing the right thing as there is nothing on the Desktop. Have you tried looking in Display Proprieties to see what is happening there?

1. Check for a faint image on the screen
Now, you need to check if you can see a faint image on the screen. It is very possible that after the lid is closed, the backlight stays off even when you open the screen again.

2. Check for a solid color
The next thing to check is if the screen is a solid white color. If so, it is very likely a bad connection between the LCD display and the system board.

3. Connect the LCD screen to an external monitor.
If the external video is fine, then you definitely have a problem with the LCD screen or the LCD video cable.

In most cases, if your LCD screen is damaged, it is hard to avoid a trip down to the manufacturer. However, the above are just some general troubleshooting tips that you should always try before calling the manufacturer's support line.

It sounds like you will need to tell Windows to transfer the video signal to the external screen. On most laptop computers this can be done with one of the F keys or with a combo of the FN key + an F key...
