Hello I am setting up this dual monitor setup. The pc is running Win7 Home Pre. with a dell STS2420L 24 inch as the main monitor and a second monitor dell 22' touch screen requires a usb connection for the touch model STS2220T. The first monitor is connected threw HDMI cable while the second is vga connection and the problem is when I touch the second monitor I see the action on the main monitor not on the touch screen, now if I go into the setting of the pc and change the setup to the touch screen is the main monitor it works but the goal was to have the main 1st monitor 24' on the desk and the touch off to the side that easy to reach to touch. it would not look right to have the 2nd touch monitor as the main monitor ... hopefully this makes sense and help would be appreciated.
