Pressing FN and F3 at the same time will toggle the Toughbook?s display between the Toughbook?s LCD, the external monitor/projector and both simultaneously. If the LCD does not display properly or there is a ‘Video Controller’ showing with an error in the Device Manager, install /re-install the Video Driver. Download the appropriate Video Driver from Panasonic’s website by following the link below. Extract the contents of the file, then run the Setup file (accept all default settings). You may need to restart the Toughbook.
