After receiving a call from an executive, a technician walks into a meeting room to find that the projector is not showing the s
creen of the executive's laptop. The projector shows a message that reads "No video signal". Which of the following is the FIRST thing that the technician should do?A. Adjust the laptop's screen brightnessB. Replace the projector's bulbC. Verify the VGA cable is connectedD. Ensure secondary display is enabled
No video signal means that the projector is not receiving any data from the laptop. Verifying the cable connection should be the first test you should do.
If the cable is properly connected and the projector keeps showing that error then you can move on and perform additional tests, but the first requirement for establishing a connection is that the cable is properly connected.
