I have a friend that is using a computer as a point of sale terminal. He would like to have a 22" monitor that displays slide shows and videos. This monitor would be in addition to the one he already has that is used as the point of sale terminal. Is this something that can be done using the same computer (dual monitors) or wold he have to build another computer for the one doing the slides? The computer has an Athlon 2500+ cpu in it and an AGP card with only one analog output. I figure if there is a way to do it he would need another video card as well so I need to know what a cheap option would be. Thanks!!!
