If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, may be your problem.

It also could be the settings. Check the "Graphic Properties" settings by right clicking on the desktop background then click on it. Make sure you open it up in "Advanced Mode" and then check that the laptop is set to show the screen on two displays.
