My Mac, all of a sudden, cannot connect with my external display monitor.
I spent a few hours troubleshoot and FINALLY my screen is back.
Below are 5 resolutions from my research and testing. Not all of them are working on me, but no harm to give a try.
My Device
- MacBook Air (Retina, 13-inch, 2019)
- macOS Catalina Version 10.15.4
- HDMI cable to connect with my Philips External Monitor / TV
#1 Restart the machine
Like all the technology issues, restart your machine
Result for me: Negative
I would still recommend this as a first step because restart can somehow magically solve your problem.
#2 Update macOS
- Go to the Apple on your top left corner
- Click About This Mac
- Click Software Update
- Update your Mac into the latest version of iOS
- Restart your Mac
