Splash Screens/No Signal

  • Hi,

    I’ve searched through the forums and not managed to find an answer. I’m looking to pick up a second hand monitor (they seem cheaper than TVs) and I’d like to use a PIR sensor to turn the monitor on and off. However, when the HDMI output of the Pi is turned off, won’t the monitor display a “No SIgnal” message or even a company splash screen?

    Can anyone confirm whether this is a genuine concern and, if so, how to avoid it?

    Thanks for your help,

  • @steve23p9835908 depends on your monitor. For most, the pi sends a “power off” signal, and you get no message.

    Really, you gotta play worth the parts you have to see how it works.

    Hi Steve,

    did you find one?
    I’ve got the same problem …

    Thanks MyMirror

    I used a BenQ and it had the option to disable the splashscreen. I’d suggest using Google for the monitor you’re looking at + “disable splash screen” or something like that, quite a lot of monitors have these options. I’d also suggest checking the power consumption.

    I used a PIR sensor to switch the monitor independently from the RasPi while the RasPi is running 24/7. Mainly because my RasPi is collecting data every 2 hours and writing it to a JSON that I want to be updated without interuption. The other reason was the screens power consumption in standby (I’m not at home for at least 10 hours every day and sleeping ~ 7 hours, so that’s min 17 hours standby every day) and the screen takes ~ 3 or 4 seconds to turn on while the RasPi takes quite a bit longer to start.

    Just be careful when selecting and setting up that PIR sensor with a switch for the monitor, not a lot are suitable for that power consumption and load and setting it up means working with the 220 V cable (or whatever voltage your country might have) – if you’re not sure what needs to be done, let a professional handle that. (Trust me, I learned the hard way …)

  • Did anybody find a way to disable the “no signal” or “hdmi1” or “analog” messages of a monitor?
    I have a Samsung 2231; it works fine with a pir, but only this stupid message …

    i had a similar issue, connecting RPI with HDMI vs. VGA had different behavior.
    To get my PIR working the way i want it, i had to use a HDMI->VGA Adapter and connected the display by VGA. Dont worry, VGA also supports FullHD Resolution.
