Product Information
The firmware update tool is an application used to update the firmware of a monitor. It is important to follow the firmware update pre-requisites before initiating the update process. The update process should be done with only one video input source connected to the monitor, and all other video cables should be unplugged. The Dell Display Manager (DDM) application should be exited, sleep mode should be disabled, and only one monitor should be updated at a time. The installation process involves downloading the pkg file and launching the installer, following the installation steps, and inputting the administrator password if required. The Firmware Update Utility will be launched automatically after the installation completes. The firmware update process involves initializing device status, enabling privacy permission for firmware updater in macOS 10.15 Catalina or later versions, loading the firmware file automatically or manually selecting the file, and clicking on Update to start the update. Once the updating process is completed, on-screen instructions should be followed to restart the monitor. Troubleshooting steps are provided in case of errors or issues during or after the update.
