Iiyama 64 Series displays run Android 14. You install the PADS4 Viewer app on the display to show PADS4 presentations. This page explains how to set up the display, check the firmware, install the app, and set the app to start automatically. ## Before you begin ### Supported devices * Iiyama 64 Series displays ### Minimum requirements | Requirement | Minimum | | - | - | | PADS4 Server | PADS4 2025.2 or later | | Device firmware | `LU64M79-B11-18` | ### Other prerequisites * A PADS4 Server that is set up and configured. * The Iiyama remote control. * A USB flash drive. You use it to install the app. * To update the firmware, format the drive with FAT32. ### Open the Android menu To open the Android menu, press **Home** on the remote control, and then press **1**, **6**, **6**, **8**. ## Prepare the device When you turn on the display for the first time, the Configuration Wizard starts automatically. If the wizard does not start, or if someone used the display before, reset the display first. ### Reset the device Reset the display to clear the storage and prevent software conflicts. A factory reset removes all data and settings from the display. 1. Open the Android menu. 2. Select **Settings**. 3. Go to **System Tools** > **Factory Reset**, and then select **Factory Reset**. 4. Press **OK** to confirm. When the reset is complete, the **Welcome** screen appears. Continue with [Complete the first-time setup](#complete-the-first-time-setup). ### Complete the first-time setup 1. On the **Welcome** screen, select your language, and then select **Start**. 2. On the **Security Setting** screen, make sure that **SICP Network Port** is turned on. 3. On the **Network Setting** screen, select the network type, and then configure the network. 4.

Select **Settings**. 3. Select **About**. 4. Compare the firmware version with `LU64M79-B11-18`. If the version is different, [update the firmware](#update-the-firmware). ## Update the firmware Contact Iiyama Support to get the correct firmware file. Do not turn off the display during the update. 1. Format a USB flash drive with FAT32. 2. Download the firmware file from Iiyama Support, and extract it. 3. Copy the extracted firmware file to the root folder of the USB flash drive. 4. Insert the USB flash drive into the display. 5. Turn on the display. The display shows this message: `Do not power off the TV during the upgrade. Waiting...` 6. When the display asks you to, remove the USB flash drive. ## Install PADS4 Viewer Install the `PADS4WebLauncher.apk` file from a USB flash drive. You find the file on your PADS4 Server in `http(s):////apps`.

Replace `` with the IP address or host name of your PADS4 Server. Replace `` with your PADS4 domain. The default domain is `PADS4`. 1. Enter the PADS4 Server location. 2. (Optional) Enter a name for the Viewer. If you leave the field empty, the PADS4 Server generates a name. 3. Select **Start**. 4. Set **PADS4 IIyama Touch** as the Home app, and then select **Always**. The Viewer connects to the PADS4 Server. ## Start the Viewer automatically Set the app as the custom app of the display.
