I have a new 14" MacBook Pro and an LG 27UP880 monitor.

I have the MacBook connected to the monitor with a USB C cable and that supplies power and also the MacBook can deliver the video signal through it, as it should.

When I was setting up the MacBook and installing software, I had to reboot a few times. Now, with the monitor connected and working, if I reboot the MacBook, the USB C port of the display seems to stop outputting power and the MacBook also cannot send the display to it. I tested the USB C from the monitor with another USB C device and there was no power. If I remove the power from the monitor for a few seconds and then power it again, the USB C port seems to work fine again!

Anyone else have this issue, or know what the problem could be?
