This one worked for me too! Thanks!
I am still struggling with this. Copied and pasted the code above into a new .sh file - file path: /home/pi Went into the crontab and the time came and went. I have repeated the steps multiple times to no avail - any known bugs with Pi 3 B+? Do I need to run the cron as a super user?
Thanks but, tvservice only works for all driver. It doesn work for example with "tvc4-kms-v3d" driver. Any other solution?

Nice! Using this, instead of the original rpi-hdmi.sh, works with my HDMI-to-DVI adapter-connected to an old monitor, where the original could turn it off, but not back on again.
