Throwing on "Mouse Trails" or "Pointer Trails" in Control Panel, Mouse, Pointer Options may help you see the pointer if you can't.

Other than that, Zarak - you get NOTHING on the TV at all? Just black? Is there a setting for refresh & resolution, etc for the second display? If so, try changing it to something your TV will handle (labelled 640x480-60Hz or 720x486-60Hz)?
