      If your ViewSonic monitor displays wrong or abnormal colors, begin by checking the video cable to ensure it's properly and securely connected. Loose or broken pins in the cable connector could cause an improper connection. If issues persist, try connecting the monitor to another computer. For older graphics cards, consider contacting ViewSonic® for a non-DDC adapter.
