Before the update starts you can create a safety fo your data. We advise you to do that again and again just to be sure that if a failure happens, you will still get all your original settings
The updates are made for "exe" formats and you get them by double clicking. Download the file, copy it into an empty USB Stick, double click to get it and confirm with "OK". After you've done that you should find a folder in the USB STick named "autoinst".
Plug in the USB stick at the back side of the display and turn the electricity off and on to start the installation. Follow the instructions on the display... you will be asked to remove the USB stick. The display will restart then.
