When a macOS desktop computer boots, no image appears on the screen, but a chime sound is heard and normal indicator lights illuminate. The monitor is linked to the computer, and the power light is illuminated. What should the next step in the troubleshooting process be?

A Try the display on another computer or another display on this computer.

Most macOS devices will generate a chime sound after a successful bootup, so we know the issue isn't with the motherboard. Try another monitor or this display on another computer before going that route. That will immediately narrow it down. Remember that if it isn't the display, it's most likely the video card.
