Mini Display Port Stopped Working (MacBook Air)

I have a MacBook Air (2015) plugged into an external HP Monitor via Mini Display to HDMI. It worked for a year and has just recently stopped working. If i restart the computer a few times and do the Command + Option + P + R reset it sometimes works, but not every time. Any suggestions to get the mini-display port working properly again?

Reset SMC by following the directions applicable to your MacBook here ➔ How to Reset SMC. If that does not solve things then-
Reset NVRAM/PRAM by following the directions applicable to your MacBook here ➔ How to Reset NVRAM/PRAM. If that does not solve things then-
Enter ➔ Safe Mode and see if the screen issue still exists in Safe mode. Log out of Safe Mode and then reboot computer. If that does not solve things then-
Finally if none of the above works then you can enter ➔ macOS Recovery Mode and reinstall the macOS and see if that solves it.

if Axel's advice did not work,

check to see if the plug fully plugged in?

sometimes i don't plug mine all the way in and get frustrated , then i realize the TV part is not in all the way.

could be the chords itself as well, or the setting in monitor needs tweaking.
