How to Connect a MacBook to a Monitor or TV

Connecting a MacBook to a monitor is simple when the cable matches the ports. The confusing part is knowing whether you need USB-C, Thunderbolt, HDMI or an adapter.

Identify Your MacBook Ports

Most modern MacBooks use USB-C or Thunderbolt ports. Some MacBook Pro models also include HDMI. Older models may use Mini DisplayPort or Thunderbolt 2.

If you are not sure, check your MacBook model and compare the port shape with Apple’s support guidance.

Check Display Support

Not every MacBook supports the same number of external displays. Open System Settings, use the Help menu for your Mac specifications, and check Display Support or Video Support.

This is especially important if you want two or more external monitors.

Choose the Right Cable or Adapter

If your monitor has USB-C, a USB-C or Thunderbolt cable may be enough. If your monitor or TV uses HDMI, use an HDMI port or a USB-C to HDMI adapter.

For high refresh rates or high resolutions, use a cable and adapter that support the display’s full capability.

Adjust Display Settings

After connecting the monitor, open System Settings and choose Displays. You can change resolution, brightness, arrangement and whether the Mac mirrors or extends the desktop.

If the Monitor Does Not Work

Make sure the display is turned on, the cable is firmly connected and the correct input is selected. In Displays settings, hold Option to reveal Detect Displays on some macOS versions.
