Display Select Problem

[jbs]

I have an IBM ThinkPad T30. When I first tried to hook up my tv as a second display monitor I went through the whole display settings and IBM control panel to properly set it up, but in the process I disabled something that doesn't seem to be possible to re-enable.

Before, when I pressed Fn+F8 a little screen popped up with the selection (LCD Only, LCD+TV, TV Only), but now the screen doesn't show up and it just cycles though the available displays each time I press the combo. I remember I disabled tha on-screen display select option, but the question is if there is a way to turn it back on?
