Ask HN: Dunkelflaute' turns off my monitor

I'm based in Denmark and blackout or power grid issues are a non issue here, as far as I know. I also have three state operated wind turbines when looking out the window (not that it probably matters here) but I can easily tell if the wind is blowing.

My problem is that today, and in periods during winters, we sometimes have periods of what Germans call 'dunkelflaute' - foggy weather where the turbines stall and solar panels go dark. And then my monitor turns dark! I can sometimes get it back after switching it on and off a few times, but it will soon go dark again on "those days", where I work on a laptop instead.

Previous years I didn't grok the spooky correlation/causation, but I clearly see it now.

The monitor (which I really like, Dell UltraSharp 43", running at 53 watts) is connected to a Mac Mini M4 via a HDMI cable (5 meters long). Changing the HDMI cable, the issue still persist. With a smaller Dell monitor, there are no issues. Ok, no problem, just change the monitor.

But wait... I got spooked up - is there is even such a thing as 'thin' or 'fluttering' electrical supply at this 53 watt consumption level? Is this be a first hint of a solarpunk future where data centers gobble up the "good electricity" and we are left with "leftovers"?
