How to Upgrade your Firmware

If you discover that the firmware is out of date, you will need to upgrade it to ensure that you have all of the latest fixes and improvements for your hardware.

To obtain a copy of the latest firmware for your device, you can contact LG support or contact us by opening a Ticket via My Account!

You can update the firmware on a webOS monitor via a USB or remotely using the Control Manager built into the webOS device.

Local Upgrade via USB

  • Create a folder in the root directory of a USB storage device.
  • Rename the folder to LG_MONITOR.
  • Copy the Firmware EPK into the folder.
  • Connect the USB to the monitor and a message will appear on screen.
  • You will receive confirmation once the update is complete.

Remote Upgrade using Control Manager

Please note that you will need to have a saved copy of the firmware EPK saved on the machine you plan to use for the remote upgrade.

  • Using a machine on the same local network as your webOS device, open a web browser and go to the private IP address for that webOS device. Please note that you must use the http protocol. For example if the private IP for your device is, you will need to enter

You may be taken to a page that confirms that the connection is insecure. To proceed you will need to select Advanced options and choose to proceed to that IP address.

  • You will be greeted with a password entry screen, which also includes a 4 digit code for authentication. Enter the password for your device and the code you can see and choose login.

If you have not used this functionality before, there will be a default password set for your device. You can find this password in the device manual!

  • You can now upload the firmware you have downloaded to your device using the Browse button to locate the EPK on your local machine.

Downgrading your Firmware

You may find on occasion that you need to revert to a previous firmware. If this should happen, you will need to override the standard settings to force the device to install an older version.

This can be completed locally on the device:

  • Follow the steps outlined above for the Local Upgrade via USB method.
  • After you connect your prepared USB to your device, press the Settings cog button on your remote control.
  • Highlight the General option and press the 7 key on your remote seven times until the Software Update page opens.
  • You will see the option to select the firmware on your connected USB. Press the Update button to start the upgrade.

You will receive a confirmation message once complete.

If your device does not automatically restart after receiving that message, please restart manually!
