Shutting Down Projector causes display issues

Beuph

Hi! If I shut down my projector before exiting OpenLP, OpenLP detects a display change and will overlay the the presentation screen over the controls screen on the main monitor of my laptop. Reconnecting the projector doesn't solve the problem. Somehow I've been able to fix it, but I can't ever replicate exactly what I did to fix it. When I do have the projector on, I can't access the menus or specifically, the Screens settings to make the secondary screen the presentation screen again.

Any suggestions? Fortunately this has only happened to me, the more tech-y of my team. But if one my team gets stuck here and I can't help, we're in trouble!

Thanks much!

Hey Brad,

There's an option in the display settings, "Display if single screen" -- uncheck that, and it might get around your issue.

It would be great if there could be an option to disable the automatic detection of display changes in v3 so that OpenLP remembers a particular configuration of displays.

Otherwise, depending on what order you set things up in, OpenLP is continuously changing its display setup and you keep having to go in to the options to reset it.

For example if someone accidentally unplugs the projector, OpenLP reconfigures itself to show on your laptop screen, then when the projector is connected again, you have to go into the options to make it work. Or if the projector is unplugged at the end of the service before OpenLP is shut down, the next time you start OpenLP you have to reconfigure the display options again.

I may have missed something here but v2 didn't do that, it would remember the last setting even if the displays were not the same. This was easier for the tech team as it didn't matter what order things were plugged in / started up.

The option to disable the automatic screen detection (changes) would be really helpful to avoid this issue of OpenLP config getting corrupted.
(I'll test the unchecking of the single screen option)

We find that if Windows didn't see the second monitor screen or if the projector gets turned off it becomes a pain to get the settings back to normal.

If the settings are fixed and final it would be good to be able to save it as WORKING CONFIG. Then effectively it said for the hardware or OS to get to the correct state and all is fine

v2.4.6 of OpenLP was actually really dumb when it came to screen settings. The fact that it "remembered" the settings was more like a pleasant side-effect 😆

With v3.0 we tried to be a little more intelligent with the screen settings, but ultimately that removed the "remember" side-effect. It is my eventual goal to have an actual formal "remember" system, but that's not going to make it into v3.1.

Thanks for the reply raoul . That will be a nice "side effect"to look forward to.

While we look forward to the ability to turn-off the auto detection/auto config (or decline it updating the confid after it detected a change), we have been doing a little testing to see how to work around the issue of losing access to the desktop when it is covered with the full screen Display.

As you already know setting up and disconnecting everything in the correct order keep things working fine. But if someone disconnects the TV or other display component (we have many interfaces before it hits the TVs), then you usually have an issue with OpenLPs config...
... Turns out this is a simple method:

The Display (Presentation) screen in on the Laptop and covers the OpenLP Window
Use ALT+TAB to select the OpenLP Window (note when you "select" it, the window is still behind the Display
Use ALT+F4 to close the Display
TVs, Projects MiraScreen, etc are connected and powered up, all showing the same background. (We have a HDMI extender hub with a MiraScreen wireless display as the input so that we split the signal across multiple TVs)
Connect the Laptop to the MiraScreen wireless display, or HDMI (Extended)
OpenLP should pop-up to state it detected a the screen setup changed (Click OK)
OpenLP should now be displaying correctly

I attach a PDF guide with the same instructions and screenshots if that helps.
