Macbook Pro Detects External Monitor but Shows Black Screen

by

If the Macbook pro detects external monitor but shows black screen, then there could be many possibilities.

There could be a minor issue like the connectivity of cables and maybe a preference issue. A monitor could be faulty.

Let’s look at some possible solutions.

Connect the External Monitor to your Mac and restart it

If something doesn’t work, you should restart your Mac if something doesn’t work, including an external monitor. Do not disconnect the monitor before restarting. Choose Restart from the Apple menu.

After restarting your Mac, put your Mac to sleep to see if it starts working with the external monitor. Select Sleep under the Apple menu. Wait 30 seconds and then move the mouse or press a key to wake up your Mac. You can also sleep and wake up your MacBook by closing and reopening it.

Restarting your external monitor is also recommended. If you’re switching it on and off again, you should disconnect and reconnect it to your Mac.

A compatible external monitor should be used

Most external monitors do not work with every Mac. However, even if the devices are connected via an adapter, they must run compatible software.

The manufacturer’s website will tell you your external monitor’s compatibility requirements. Check the About This Mac section of Apple to ensure your Mac meets these requirements. By clicking on the System Report button, you can access information regarding your Mac’s ports.

Although Thunderbolt 3 and USB-C may appear similar on the surface, they are not alike. Your monitor should be connected to a Thunderbolt port if it requires a Thunderbolt connection. Moreover, Thunderbolt 1 and 2 and the MiniDisplay port, which is found on older Mac models, behave similarly.

Why Is My MacBook Pro Not Detecting My Monitor?

Identify the displays attached to your Mac

Sometimes you won’t be able to use an external monitor on your Mac as the operating system is unable to detect the new display. The following suggestions may help after you’ve ruled out software updates and physical connections.

Within System Preferences, go to the Displays page. You can use the Detect Displays button on your Mac by holding down the Option key. It automatically detects new displays when you press the button.

Try restarting your Mac in Safe Mode if that does not work. Hold the Shift key while your Mac starts. During a safe mode, third-party applications and helpers are not loaded. Several maintenance tasks are also performed during this mode.

Using Safe Mode may allow you to detect external displays on your Mac. After exiting Safe Mode, you should continue to be able to use your external monitor.

Select a different port and reconnect all the cables

Unplug the cables from your Mac that connect to your external monitor. It may be necessary to clean your port before reconnecting if it is dirty. Ensure that your ports and cables are in good working order before reconnecting.

If your external monitor does not work after reconnecting it, try connecting it to a different port on your Mac. It may be possible to connect to another input if multiple ones are on display. You may wish to use spare cables if you have any lying around.

Don’t use extension cables, hubs, or adapters. Use your Mac directly to connect to your external monitor. It indicates a malfunction with the accessory you were using.

In addition, make sure both your Mac and external display are connected to power.
