As Apple products continue to grow in popularity, the ability to connect external displays to Macs has become a standard feature. Unfortunately, there are times when Macs may not detect external displays, which can be frustrating. Here are a few tips on how to fix it when Mac is not detecting an external display.

First, it is essential to determine whether the problem lies with the Mac or the external display. To do this, try using a different external monitor or connecting the current one to another device. If the display works on another device, the problem lies with the Mac.

One simple solution is to check the connections between the Mac and the external display. Ensure that all the cables are connected correctly and firmly. Replace any shoddy cables if necessary.

If the problem persists, go to the System Preferences on the Mac and click on “Displays.” Here, click on the “Detect Displays” button. This action should prompt the Mac to detect the external display.

If the Mac still does not detect the external display, resetting the PRAM or NVRAM can help. To do this, shut down the Mac and restart it. While the Mac is restarting, hold down the Command + Option + P + R keys. The Mac should restart again, and the PRAM or NVRAM will reset.

Another option to try when Mac is not detecting an external display is to update the Mac’s operating system. Ensure that the Mac is running on the latest OS version by helping the software update feature detect and install any available updates.

Finally, if none of the above steps work, it may be time to seek professional help. Visit an Apple store or authorized repair centre to have the device examined by a professional. The experts should be able to diagnose and provide a lasting solution to the problem.

In conclusion, the inability to detect an external display on a Mac can be frustrating. However, it is important to try simple solutions first, such as checking the connections between the Mac and the external display or resetting the PRAM or NVRAM. If none of these methods work, consider updating the Mac’s operating system or seeking professional help.
