How do I toggle the display between the CF-51s LCD and an external monitor/projector?
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 an error in the Device Manager, install/re-install the Video Driver. Download the appropriate Video Driver from Panasonic’s website. Extract the contents of the file, then run the Setup file (accept all default settings). You may need to restart the Toughbook.
