CompTIA A+ 220-1101 Practice Question

You are in a conference room where a presenter is attempting to display a presentation from a laptop to a projector. The laptop and projector are both powered on, but the projector continues to display a 'No signal' message. Before checking the physical connections, which of the following should be verified FIRST to resolve this issue?

  • Switch the laptop to an external display mode using the function keys.

  • Replace the bulb in the projector as it may be too dim to display an output.

  • Confirm the projector is set to the correct input source that the laptop is connected to.

  • Adjust the laptop's screen resolution settings.
