MacBooks are excellent devices, but their small screens can sometimes be limiting. Whether you are working, presenting, or being creative, connecting your MacBook to a larger display can make tasks much easier. The process is straightforward once you have the right accessories and know which settings to adjust.
Here is a guide on how to connect MacBook to external displays and devices, along with troubleshooting tips for common issues.
Your MacBook probably has USB-C/Thunderbolt 3 or 4 ports. That’s what you should check to determine compatibility.. You can plug straight into monitors that use USB-C, or grab an adapter for HDMI or DisplayPort.
HDMI Port: The newer 14-inch and 16-inch MacBook Pros released in 2021 and later feature an HDMI port. This means it should work with almost any current monitor or TV. If you have an older MacBook, however, you may have a Mini DisplayPort or Thunderbolt 2. In that situation, you’ll need some type of adapter.

Once you know what ports you have, grab the right cable:
USB-C to USB-C: For monitors that use USB-C connections.
USB-C to HDMI: Compatible with most standard monitors and TVs.
Connecting Your MacBook to the Monitor
Plug the cable into your MacBook, then connect the monitor.
Switch the screen on.
Your MacBook should detect the display automatically.
If nothing appears, try unplugging and replugging the cable or restarting your MacBook.
After connecting, adjust the display settings:
Go to System Settings, then select Displays.
You can either display the duplicate content on both screens or spread your work out across both for more space.
Adjust the resolution and refresh rate to achieve the best picture quality.
Drag the displays around to match their physical setup. This makes moving your mouse between screens feel natural.
The process is similar to connecting standard monitors. For most TVs and projectors, simply plug in an HDMI cable. Alternatively, you can connect wirelessly using AirPlay to an Apple TV or an AirPlay-compatible smart TV.
For older VGA projectors, a USB-C to VGA adapter is required to establish the connection.
Yes, depending on your MacBook:
MacBook Air with M1 chip supports a single external screen. MacBook Pro with M1 Pro or M1 Max: You can connect up to two or four external screens to these.
Before purchasing an extra monitor, check Apple's website to determine what your MacBook can handle.
Monitor Not Showing Up: Double-check your cables, restart your MacBook, and make sure the monitor is turned on.
Low Resolution: Try using a higher-quality cable or adjust the display settings.
No Sound on Monitor/TV: Go to System Settings, then Sound, and select Output, then choose the external display.
Flickering or Black Screen: This could be caused by a faulty adapter or cable. Swap them out for certified ones.
Your MacBook works with lots of devices other than just a screen:
External hard drives via USB-C or Thunderbolt.
Printers and scanners via USB-C adapters or Wi-Fi.
Keyboards and mice (Bluetooth or USB).
Speakers (Bluetooth, USB-C, or the headphone jack if your MacBook has one).
This makes your MacBook highly versatile for a wide range of tasks.
