Why is there no image on my ViewSonic Monitor when an external device is connected?
- ZZachary PooleAug 30, 2025
If you've connected an external device to your ViewSonic monitor but see no image, first, make sure the power is on. Then, adjust the brightness and contrast via the OSD Menu. Finally, check the connecting cable and ensure it is properly and securely connected, as loose or broken pins in the cable connector could cause an improper connection.
