does your monitor have the input connections needed for tv? you should be able to find this from your manual or from the viewsonic site. If it is so equipped you might find on your cable box an extension aerial connection for a second set. If everything is compatible you would either need to run a co-ax cable to the monitor from the box or perhaps get one of those sender units that you see advertised. I do not know of any monitor that can receive a tv signal without the help of a pc connected.
