I would make sure that all the cables are securely connected to both the monitor and the pc computer (screwing the screws from the cable to the port will help hold the cable in). Beyond that, the issue is likely with the monitor and not something that can be fixed by the end user.

If the device is still in warranty (and checking the cables don't work). I would recommend sending it back to ViewSonic to have it fixed.
