I have a 3 monitor setup where my 3rd monitor is my TV in the living room. I was hoping there was a way to set my primary monitor with something like PIP but able to control the 3rd monitor not just view it. Cloning the primary or 2nd monitor onto the 3rd doesn't seem to work either because of the different resolutions. Tried to look around a bit but all I found was a thread on viewing the monitor. Any help would be appreciated.

Also, will it be possible to have the sound directed to the TV instead of the computer speakers?
