Re: Newbie question about dual monitors
Hi and welcome to the forums.
The monitor will still show the desktop on the setup you have described if you swap the input from PC to TV since it's essentially a mirrored desktop. It might well be worth you investing in a cheap PCI graphics card that is capable of dual screening since then, when you want it you can have the TV as an extended desktop to your machine.
