For the past few years, my computers have failed to wake up the large 4k monitor connected to my dock, which has been a source of great annoyance to me.

Just a few days ago I came across something that suggested maybe the issue was that the monitor needs HDMI 2.0+, so I bought a newer HDMI cable and now it works perfectly, so if you are having a similar problem, might be a good idea to try a newer cable.
