Main view not displaying presentation

idealtrucks

I've got a new computer after our old computer crashed, and now I can display the presentation to our projectors fine, but the main view in web browser is blank. Just showing the desktop image. I'm also trying to use NDI screen capture to send this to our OBS machine, and it's also just displaying the background. So, I'm assuming they are using similar technology for this. What's changed that it's not displaying the presentation in the main view? The only thing I can think of different is that I'm running on this computer as an Admin account.

I also have this same issue. I am running web remote 1.2.4. I have another location that that is running web remote 1.1.0. It seams to work. Don't know if the updated version is the issue? can I install an older version of web remote to test, and if so how?
Ok... after more testing I have never be able get the slides to display through the web remote at .../main.
When I connect NDI Tools Screen capture, as I cycle through the slides sometimes some of the slides will appear and sometimes the windows desktop shows. It is not the same slides that show, random, shows one time, desktop the next time... maybe a timing problem?

I also tried NDI tools with it and was finally able to get it to work with NDI tools fairly consistenly by running from a batch file, and disabling hardware acceleration in QT. The Main view was working with this workaround also, but then stopped yesterday during service just all of a sudden. Had worked fine during practice.

If there is someone out there (smarter than me) that would be willing to share/explain a solution this (to the 'main' output not displaying in remote web interface), our service would be very grateful. We have spent years making custom hymn overlays that only work through OpenLP and now can't display them in the service.
In addition to the previously posted testing, I have tried adding a USB graphics card to isolate the PC's onboard graphics, however that did not make any difference. Still no output of the main. The 'stage', 'cords', and 'service' views all display fine.

I run openLP through a batch file like this and it works most of the time:
@echo off
set QT_QUICK_BACKEND=software
start "" "C:\program files\OpenLP\openlp.exe"

Thank you for this. While this can be used, and does work most the time. disabling this is not ideal in our work flow.

I don't know if this is the place to post this but maybe it will get to them.
This is not a fix, but hopefully this observation will inspire someone that can, to find a permanent solution.
...With OpenLP closed, If I go into Windows Display settings and change the screen resolution on the display that is being used as the display for OpenLP to something different ex. 1280x800, then launch OpenLP (it will probably popup with "There is a mismatch between screens...").
At this point "Main" will still not display on Remote Interface. But if I then (with Open LP running) go to Windows Display settings and change the screen resolution (the display that is being used as the display for OpenLP) back to ex. 1920x1280...then after reloading the song, it then "works", until you restart OpenLP (or go into OpenLP and change screen settings).
