• If the vCast receiver app prompts for an upgrade key after a potential RMA replacement this is caused by Viewsonic not having entered the new display into their vCast servers.

• Trying entering this code if prompted for an update key as shown in the image. "ZBCCTA7G"

• If this code does not resolve the issue then a case must be submitted.

• Pin code entered could be incorrect. Double check that the pin code entered is what is currently shown on the display and check for "0"s instead of "O"s

• Make sure the vCastSender program on the laptop is up to date with the latest firmware from the Company Portal. It may at times need to be uninstalled and re-installed if the error persists

• If the cast fails with a "waiting for the receiver to accept" error then try casting again and watch the Viewsonic display. A popup at the bottom of the screen should show with a button to "Allow" the cast that must be pressed on the screen.

If the above methods do not help then there is a way to clear the data on the vCastReceiver app from the Viewsonic that may help resolve some issues.
