Window 7 Home Premium

On my laptop I press the fn key and then there's one of the f keys that switch from the laptop screen to the external monitor and then both as you toggle through. On my main computer, I'm having a problem with it not sending the signal to the monitor which is connected through an HDMI cable as well. I have to unplud the connector and plug it back in so that it detects the connection again. It works then, but I haven't figured out what's causing it yet.
