So, how did I fix it? I will explain it in some simple steps, so next time you will not get panic when your external monitor will turn off in the middle of nowhere. 

How to Fix Macbook External Monitor Keeps Turning Off

1. Check Your Cable Connection

The first step in fixing your monitor turn-off issue is to check the cable connecting your MacBook to the external monitor. Ensure that the cable is securely plugged in and free from any damage. If the cable is damaged or loose, it could be the reason for your monitor turning off. Try using a different cable and see if it makes a difference. Sometimes it happens that the monitor is not connected to the MacBook and we keep getting frustrated, it might be due to a faulty cable or any other error. Just make sure, your external monitor is connected to the MacBook properly.

2. Keep Your Drivers Up-to-Date

Outdated drivers can cause problems with your external monitor, so it’s crucial to keep them updated. To do this, simply go to the Apple menu and choose “System Preferences.” From there, click on “Software Update” and see if there are any updates available for your MacBook. Updating your drivers could be the solution you need to keep your external monitor from turning off. You can also opt for manually updating the drivers of your Macbook by simply going to the official website of Apple and you will be able to update the drivers. 

3. Reset NVRAM/PRAM

NVRAM (Non-Volatile Random-Access Memory) and PRAM (Parameter Random-Access Memory) store certain settings on your MacBook. If these settings become corrupted, it can cause issues with your external monitor. To reset NVRAM/PRAM, shut down your MacBook and then hold down the Command + Option + P + R keys. Continue holding the keys until you hear the startup sound twice. This simple step could solve your monitor turn-off issue.

Sometimes, the simplest solution is the best. If your external monitor is turning off, try restarting your MacBook and see if it fixes the problem.
