If a user cannot project their laptop display onto an external projector, which is the BEST first step to try?

Using the Fn key to redirect display to the external video port is a logical first step when addressing issues with projecting a laptop display onto an external projector. Many laptops have a specific function key (often in combination with the Fn key) designed to switch the output from the laptop screen to an external source, such as a projector or a second monitor. This functionality is built into the operating system to manage multi-display setups.

When a user attempts to connect to a projector, it is common that the display settings may default to the laptop's screen rather than recognizing the external device. By utilizing the Fn key along with the designated key for display output (usually marked with an icon of a monitor), the user can quickly attempt to resolve the issue without needing to delve into more complex troubleshooting steps.

Other steps, like checking the projector connection, restarting the laptop, or updating the graphics driver, can certainly be relevant in a comprehensive troubleshooting process but may be better suited for after ensuring that the correct display output method is being utilized. These options might involve more time or complexity than is necessary for a first attempt at solving the problem.
