Recently, my monitor went dead on me which could only mean one of the following:
And so I tried connecting my MacBook Pro to the monitor via HDMI but still through the same USB-C port. The monitor works, so I know 1 and 3 are out.
I tried the DisplayPort cable on another monitor. It worked so 4 is out.
Which means there is a very good chance the DisplayPort input on my monitor is the cause of current predicament.
I was about to call support but then I came across this interesting thread, which suggested that users facing DisplayPort issues disconnect the power cable from their monitors for a couple of minutes.
It makes no sense and when quizzed, the user who suggested this fix only said: “Not sure, it just happens sometimes with DisplayPort.”
I was skeptical but a couple of other users have reported positive results so I decided to try it for myself.
Miraculously, it worked! My DisplayPort came back to life.
Unfortunately, my joy was short-lived. It became unresponsive the next day, which suggests a deep-rooted problem with my monitor that requires a higher level of intervention.
Though my story doesn’t have a happy ending, if you are facing DisplayPort issues, it won’t hurt to just unplug the power for a couple of minutes and see if it comes back to life.
Specifications are not everything. It's what you do with what you have that matters.
