Make sure your cable is plugged in good in the computer, and the monitor.

take a screenshot of the line showing, paste it into a new image and slide it to the right/left. if the purple line is on the screenshot it's comming from the graphics card, else it's on the monitor.

could be cable/not fully plugged or something wrong with the monitor itself.
