AHAHAHA i just spent 2 hours trying to sort it, so I went over to the TV and its not even plugged in all the way.........

So I just bought a HDMI cable so I can put a film on my computer and it go to my TV, but the TV says no signal even though it is showing up as a secondary monitor on my computer does anyone know how to fix this? I'm not bothered about being able to use both at once, just to be able to switch between them.
