Yeah I did all that, the TV's been detected, but it doesn't show up. I'm guessing my graphics card's tv-out connector must be broken, I tried it with a laptop and it worked. Oh wait, I done this but I don't really wanna extend my desktop I just want my tv to show what my laptops showing, how do I do that?On the display/Settings tab, choose AdvancedThen you should be able to change it under one of the tabs, depends on which graphics card you have I think. Probably under the display or monitor tab.
