Setting up a projector with a MacBook is a quick and easy task that can help you take your presentations or other multimedia content to the next level. 

Whether you’re a student, teacher, office worker, or a business executive, or someone who needs a projector to showcase how to make a website an icon on Mac or how to disable notifications, for example, having the ability to project your laptop’s screen onto a larger display will undoubtedly come in handy when there is an audience in front of you.

That said, there are some specific steps and methods that must be followed when attempting to connect your MacBook to an external projector. To get the most out of this setup, here are 10 simple tips to make a projector work with your computer.


1. Check Compatibility

Before taking any action, make sure both your MacBook and the projector are compatible with each other. 

This means double-checking that both devices have the necessary ports and connections needed for setup. If not, you may need an adapter cable in order to connect them together.

2. Change Your Display Resolution

When connecting a projector to your MacBook, it’s important to make sure that your laptop’s resolution matches with the native resolution of the projector. 

To do this on your Macbook, simply go into “System Preferences” then “Displays” then “Display Resolution” and select the appropriate option for optimal performance.

3. Connect Your Devices

Once you’ve determined the compatibility and have adjusted the resolutions accordingly, it’s time to physically connect them together using either an HDMI or VGA cable (depending on which port types are available). 

Make sure you secure the connection tightly before continuing on with further steps as any loose connections may result in poor quality images being projected onto the external display.

4. Select External Display

Once you are finished with the connections between both devices, launch System Preferences again and select “Displays”. 

Here you should see both options of either using only the internal display (your laptop) or using multiple displays (both internal plus external). Choose multiple displays if you want content from both screens showing simultaneously or choose single display if only content from one screen is desired at any given time.

5. Adjust Brightness & Contrast Settings

Depending on how far away your laptop is from the projected image source, there may be some difficulty seeing what is being displayed due to brightness levels being too high or too low (as well as incorrect contrast settings). 

To fix this issue manually adjust each device’s brightness/contrast settings until you find something more suitable for viewing purposes by going back into System Preferences > Displays > Color & Brightness tab respectively.

6. Check Angle & Position

One common mistake made when projecting images from a laptop onto an external display is placing it at an awkward angle or in an odd position relative to where viewers may be sitting/standing; resulting in distorted visuals on screen (due to lens distortions caused by improper placement). 

Therefore it should always be checked whether the devices are facing each other correctly before starting up any presentation material, otherwise, such distortion will occur and ruin its overall appearance/visual appeal once shown publicly so ensure they’re positioned appropriately beforehand!

7. Power On Both Devices

After making all necessary adjustments and positioning changes have been completed it’s time to press the power button on both the MacBook and projector.

8. Enable Mirroring Option

If needed, enable mirroring mode through system preferences by considering how many windows/apps will be opened while giving a presentation. 

The feature allows the presenter to easily switch between different pieces of applications without having to worry about adjusting size scaling manually every instance.

9. Adjust Volume Settings

When outputting sound through external speakers connected directly to the computer, volume levels should also be taken into consideration, ensuring nothing is too loud or too quiet when playing back multimedia content during the presentation itself so the audience is able to hear what is being said without having strain ears order understand everything clearly.

10. Check for Updates & Warnings

Finally, before starting, make sure to check both devices for software updates or warning messages, which may prevent everything from running smoothly. 

If an update or a different type of notification shows up, take care of it. It should not require too much time depending on what the process is. Ideally, though, you want to check for these things before starting your presentation as an extra precaution.


Overall these steps should help ensure proper projector use with Macbook laptops, allowing presenters to give their best performance during presentations without worrying about technical difficulties. Following these tips should make setting up much easier as well, so don’t be afraid to try them out.
