Q: What do I need to make the touchscreen work on my PC, We have the cable to go from the monitor to the computer, but need to know what kind of port or card we need to get to enable the touchscreen to work?
A: Most modern touchscreens use VGA (15-pin connector) for video and USB to control the touch interface. Most if not all machines should have both these ports available. Then you just need to install the drivers (usually on a CD with the screen) and go.
