Since the computer detects the projector as a second display, it is likely that the projector is working properly. The issue is most likely that the computer is not outputting to the projector. This can be caused by a number of factors, including: - The projector is not selected as the primary or secondary display. - The projector is set to the wrong input mode. - The projector's cable is not properly connected. - The projector's settings are incorrect. If the issue persists after verifying the display settings, then the next step would be to update the workstation video drivers. However, this is less likely to be the issue, since the computer is able to detect the projector. The projector's bulb has burned out is the least likely issue, since the projector is able to turn on. Therefore, the most likely issue is that the display settings need to be verified.
