Apple also advises adjusting the screen resolution in System Preferences.

If using more than one monitor in a ‘daisy chain’, unplug all monitors and test using just one.

Unplug the video cable (if using a separate monitor) and plug it back in.

Remove all display extenders and switches, and any other devices between the Mac and monitor.

Confirm that all cables are connected securely.

Check the power supply to the Mac (and the power to the display if using a separate unit).

If your display isn’t working the advice is to: If you think it’s a problem with your monitor, then take a look at thisĪpple Support document for advice on troubleshooting a display. It is possible that your Mac does turn on, but doesn’t boot up because it can’t access the display – if that’s the case you are most likely having trouble with the display hardware (rather than a broader startup issue). Have a listen to your Mac to see if it’s making any sounds during boot-up. You could have a problem with the display you have plugged in, rather than the Mac itself.
