Monitor consuming too much power

I received this message:

enter image description here

and then my external monitor shut off. Nothing else is plugged into my monitor and the monitor is plugged in to the wall outlet so the monitor should not be consuming much power from my mac.

For the USB-C cable that goes from my monitor to my mac, the end that plugs into the mac was quite hot.

It seems that one of the following is broken:

  • Mac
  • USB cable
  • monitor

Any idea which one is the cause or how to figure it out? I'll try swapping the things that I can...


Solution 1:

Replacing the USB-C to HDMI cable fixed it for me.
