Right click on desktop and click Screen Resolution, then, once that Window, click on Detect, at the top right corner. If 2 monitors are detected.
Then maybe the other one was turned off, try a key combo of Fn + F7

There is a possible chance that the screen died. Let's hope for the best.
It would help me if you provide more detail on the model? Are you talking about the HP Slate 500? If the screen on the slate isn't working.. RMA it.
