There is a feature pictured above the FUNCTION keys ...one of them looks like a Laptop | Monitor. It selects between external display, external display duplicate and display extend. Depending on how you have it set, it may be Quickset enabled without having to press the Fn key in combination. Please use this key to bring the computer back to "computer only." If this answer was helpful please remember to hit the YES button and if you need further assistance don't hesitate to contact.
