Output to multiple monitors

I have a computer with a monitor and then 2 43" TV displays mounted in the sanctuary.  Windows sees all 3 displays.  OpenLP is also able to detect 3 displays / monitors but there isn't a setting (that I have found) to direct the output to both monitors.  I have to pick one of the 3 displays.

Am I missing something or is this software not capable of simultaneously outputting to both screens?


  • OpenLP is setup to display to a single 'live' display, but Windows will allow you to duplicate your two TV displays.  Then you select either display in OpenLP and It will display to both TVs.  If you need help duplicating your screens in Windows, please remember to tell us what version of Windows you are running.

    Another option is to use a Video spliter for the two TVs.  This is more of a last resort....you said Windows sees all three displays....Try duplicating your displays in Windows!
  • JohnM,

    Thank you sir!  My video card was flaky, so, I did replace it.  Once I did that, I had stability, finally.  I was able to clone monitors 2 & 3 and OpenLP saw it as "screen 2".  I'm in business!
  • I have a similar issue. Laptop, Win 10, and a single HDMI output. I have set up display extension and it works fine with the win desktop. However, everytime I attempt to send a slide "live", it displays on the laptop display instead of the TV monitor which is upfront in the sanctuary. Repeat - all windows activities allow me to move things to the monitor and display them with no problem. But OpenLP only seems to display slides on the built-in laptop display. Where's the switch?
  • Check the settings for OpenLP.  The General Tab has a "Select Monitor for output Display".  You may have to try different settings to see what works for you.  My Windows 10 laptop with a VGA projector and an HDMI projector is set to display 2, but when I use the windows identify screens it says the HDMI projector is #3....
    I suggest you make your settings in OpenLP, save your service if you have one and restart OpenLP.  This may not be required, but if you do it this way you will see the OpenLP application on your laptop screen and the presentation screen on your display.
  • Remember that it does run web servers so you can show the Main View, Stage View and Chord View on "other" screens (devices) by connecting them to the web server host. This way you can have more screens.

  • If Web remote plugin is enabled and listens on all interfaces e.g. then link to Live view is http://localhost:4316/main (from the computer openlp runs on)
