OTA Firmware Update:
Executing an Over-The-Air (OTA) firmware update constitutes a differential upgrade that preserves the current configuration of the display. All parameters will be retained. This procedure is advisable for applying the most recent patch to the display model. The OTA firmware update can be obtained either through the display’s system update functionality or from the download section of the product page.
Settings -> System -> System Update
Full Firmware Upgrade:
Executing a full firmware update constitutes an essential procedure that restores the display to its factory settings and reinstalls the operating system. The necessary instructions and files will be provided by ViewSonic’s technical support following initial troubleshooting and must be flashed on-site via a USB drive. A full backup is recommended prior to performing this step.
