Running digital signage software on Pi OS 24/7 to inform people about Covid-19 and such. In the weekends and at night this is not necessary.

Is there software or a setting where I can schedule a screen off/on time?

Thanks

Schedule a cron job which disables the screensaver / energy saving (xset s off -dpms) on Monday morning, and another job which re-enables the the screensaver / energy saving (or simply reboots the system) on Friday night.

Or permanently disable the screensaver/DPMS and manage the HDMI output using tvservice --off / tvservice --preferred

    The cron job set me on the right path, got it working with:

    Monitor off: 30 17 * * 1-5 /usr/bin/vcgencmd display_power 0 Monitor on: 30 07 * * 1-5 /usr/bin/vcgencmd display_power 1
