Many MacBook users reported that the HDMI connection is not working for them. This can be an issue, especially if you want to connect your MacBook to an external display. However, there’s a way to fix that.

What to do if HDMI connect isn’t working on MacBook?

1. Check if everything is connected properly

If your HDMI connection isn’t working, make sure that your MacBook is properly connected to an HDMI device. In addition, you can try the following:

  1. Turn off the HDMI device while keeping the MacBook connected.
  2. Disconnect the HDMI cable from your MacBook.
  3. Wait for few seconds and connect the HDMI cable back to your MacBook.
  4. Now turn the HDMI device back on.

This is a simple workaround, but it might come in handy, so be sure to try it out.

2. Check the HDMI cable

If HDMI never worked on your MacBook, it’s possible that there’s an issue with your HDMI cable. Apple products work best with Apple Certified cables, and if your cable isn’t certified, you might have to replace it.

Alternatively, you can consider purchasing an Apple HDMI cable.
