        Thanks this is very useful information that I didn’t know before.
        I have issued the sudo tvservice -o command and it did indeed shut down my monitor.
        But what I am trying at the moment is to have it shutdown and wakeup the monitor with a usb webcam now.
        That’s what I’m struggling with.
        Cheers

          One interesting thing I like about the second way is it seems easy :) lol.

          Would it be possible to say have the screen come on 6-9am in the morning Monday to Friday then come on again 4-10pm as everyone out at work or school during the day. Than say set it so that its on 8am till 10pm on a saturday and sunday when everyone is usually about.

          Thanks

            Sure, this is possible. For the beginning it seems easy, because u needn’t any optional hardware :)

            For your understanding how cronjobs works u should note the following:

            * * * * * user executive_command
            ┬ ┬ ┬ ┬ ┬
            │ │ │ │ │
            │ │ │ │ └──── Weekday (0-7, Sunday is 0 or 7)
            │ │ │ └────── Month (1-12)
            │ │ └──────── Day (1-31)
            │ └────────── Hour (0-23)
            └──────────── Minute (0-59)
            

            So for your special wish ^^it should look like this:

            # /etc/crontab: system-wide crontab
            # Unlike any other crontab you don't have to run the `crontab'
            # command to install the new version when you edit this file
            # and files in /etc/cron.d. These files also have username fields,
            # that none of the other crontabs do.
            
            SHELL=/bin/sh
            PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
            
            # m h dom mon dow user  command
            17 *    * * *   root    cd / && run-parts --report /etc/cron.hourly
            25 6    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
            47 6    * * 7   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
            52 6    1 * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )
            0 6,16  * * 1,2,3,4,5   root  /home/pi/monitor_on.sh
            0 9,22  * * 1,2,3,4,5   root  /home/pi/monitor_off.sh
            0 8     * * 6,7   root  /home/pi/monitor_on.sh
            0 22    * * 6,7   root  /home/pi/monitor_off.sh
            #
            

            Or if you don’t want to create the *.sh files u can also just type the directly command.
            Like this:

            0 6,16  * * 1,2,3,4,5   root  /usr/bin/tvservice -p
            0 9,22  * * 1,2,3,4,5   root  /usr/bin/tvservice -o
            0 8     * * 6,7   root  /usr/bin/tvservice -p
            0 22    * * 6,7   root  /usr/bin/tvservice -o
            

            Last thing is the extremely easiest way because u just need to modify the crontab. there is nothing else needed at all.
            Just put these commands in your crontab and u are done ^^

                { exec(‘xset dpms force on’, null); }
                { exec(‘xset dpms force off’, null); }

                These commands do work. I just tested them on my desktop machine with a monitor connected through DVI and a laptop. Displays are immediately turned off (standby) and on. Here’s the laptop.
