Mac mini does not wake monitor after sleep

Mac mini with M1 chip was bought yesterday (22/01/2022). It never wakes the monitor after sleep. I have to turn the monitor off and on again to get it to wake. I have been using the monitor for several years with a Mid 2014 15" Mac Book Pro without any problems.


Cable: HDMI

Monitor: Dell U2713H

Mac mini 2018 or later

I have experimented with a couple of cables which I had around the house.


USB C to HDMI: The monitor goes completely black. However, it never goes into a low power state. It wakes immediately.

Certified for UHD, 4K HDMI to HDMI cable: Monitor enters low power state and wakes immediately. This is what I would expect.


Thank you everyone for your help.


It's interesting that Apple never comments on this issue and just lets everyone flail around buying cables and even replacing monitors which they believe to be at fault.
