My original thread was archived here.
TL;DR I couldn't get my HDMI monitor to go dark. Tried power settings, task scheduler, batch file, monitor settings - nothing worked.
I finally figured out that my USB game controllers needed to be disabled. I have a USB hub with power buttons, so it's easy.
Now the monitor goes dark after 20 minutes (following my power setting.)
