A user calls the help desk complaining that the DVI connector on their laptop is not functioning properly. The laptop’s built-in display is working perfectly, and the user reports that a technician successfully connected the user’s laptop to a projector only the previous day. What is the first thing you instruct the user to do?
  1. Make sure none of the DVI pins are bent.
  2. Check the video drivers in the device manager.
  3. Try using the Fn key to press the Toggle Display button on the keyboard.
  4. Replace the DVI cord.
Explanation
Answer: C - A user having difficulty connecting an external display to a laptop should first try the Fn key to press the Toggle Display button on the laptop’s keyboard.

Key Takeaway: Most laptops have a toggle-display button on the keyboard to make it easier for users to connect external monitors or projectors. On many laptops, the correct combination is the Fn key and the F3 key pushed together, however this varies depending on manufacturer. The other answer choices are possible solutions, but the toggle key is the first thing to try on a laptop.
