Computer Troubleshooting

[powderkeg02]

Initially I had both my tv and computer off. I connected the dvi to the tv and the hdmi to the laptop and turned them both on. I had no issue using my laptop as i tried to sync the computer to the TV. However i must have accidentally hit something in the graphics options as my laptop screen went black. I unplugged the hdmi cord from my laptop and the screen came back up. But now for some reason everytime i plug in the hdmi cord to the laptop the screen goes black. When i take it out it the screen comes back up. Did i change something that is causing this to happen? Any help would be greatly appreciated. Thanks

Possible did. 

You should be able to press the FN/F5 keys to switch back.

I tried that and it didnt do anything. Is there anything else that may be causing this problem?

Ok so I finally got it fixed and here is what I did. I held down on the fn button while the laptop was plugged to the tv. Different options came up. You can use the mouse on the computer to click the options. When i clicked the right option it now works. Try the fn and change some settings until you get the right one. Thats what I did.
