      Hi,
      for my new magic mirror I have a SyncMaster TA550 monitor / tv. The problem is that after the PIR sensor stops the signal on the screen I have the message: without signal, check the connection …
      Can anyone help me how I can disable this message?
      Thanks,

        @george u cannot disable the message, it is part of the tv firmware.

        this is why you need to use different commands to turn off the TV and NOT the HDMI port.

        none of my TVs support this capability, so I hide all the modules instead

            @george NONONO :-) . first try out a bit more.
            I think MMM-NewPIR has integrated several possibilities of turning off the monitor or hdmi.
            Play with these, you might be successful.
            I think my monitor (also a syncmaster) can behave both ways however you swithc it off.

                @george i just replied to someone else on discord

                there are different commands to turn on/off display devices… and they work in different places
                tvservice is a pi only command
                https://www.raspberrypi.org/documentation/raspbian/applications/tvservice.md
                vcgencmd is one to control the hdmi port (turn off, and display MAY show ‘no input’)
                https://www.raspberrypi.org/documentation/raspbian/applications/vcgencmd.md
                and cec-utils (cec-client) can control the tv on the end of the hdmi cable (for cec compliant devices)
                https://pimylifeup.com/raspberrypi-hdmi-cec/

                tv service works on pi4 to turn off hdmi port, but not back on.
                vcgencmd worked on pi 4, but montior displayed no input, cec-utils worked turned off/on monitor

                [11:45 AM]
                the PIR module has to use the right commands… I thought NEWPir supported cec-client… but haven’t tried it…

                sam — Today at 11:58 AM
                New-PIR does support the CEC commands, and vcgencmd and tvservice…
                using mode in the module config screen section screen: { } I think
                5 modes are available:

                • mode: 1 - use vgencmd (RPI only)
                • mode: 2 - use dpms (version RPI)
                • mode: 3 - use tvservice (RPI only)
                • mode: 4 - use HDMI CEC
                • mode: 5 - use dpms (linux version for debian, ubuntu, …)

                my advice to the other user was to logon to the pi via ssh and try the commands as documented in the links to figure out which on works and then use the mode in the NEW-Pir module config
