if it is truly a stand alone monitor without its own software or internet connection i would need the exact model number to see if there is any way to do it. Is there a specific reason that you would need the firmware update ? I usually recommend against doing firmware updates unless there is an actual problem that you know it will solve. New updates are usually to address a specific problem and they sometimes cause new problems. Also if the update fails you are generally left with an expensive paperweight as there the machine wont run and there is no way to fix it outside of the factory.
