When connecting VZ-1 HD directly to a monitor/projector we recommend the following steps:
Plug the VZ-1 HD to a power outlet, but don't plug in the VGA cable yet to any end.
Turn on the VZ-1 HD, and then plug in the VGA cable to the VZ-1 HD.
After that, connect the VZ-1 HD to your monitor/projector using the other end of the VGA cable.
If the problem still persists, please try a different USB power adapter. You can use any USB power adapter from another working VZ-1 HD, smartphone or tablet. You can also try using different VGA cable or monitor. Lastly, you can try different resolutions using the resolution selector in the front of the camera.
