Dual Screen How to stop 'Zoom' Window Switching Monitors During Screen Share

If anybody is still having this issue, I don't have a fix, but we've been able to mitigate it by being careful about the order that we do things. It seems, for our system, that if the monitors are not turned on until zoom is up and running, then zoom behaves itself. You may need to try different orders of operations to find what will work for your setup. Once we started getting consistent about the order, our issues went away. Depending on the types of connections, adapters, and splitters involved, you might need to go as far as unplugging the cable until zoom is running.

Hello, just FYI this fix works for our set up:

Go into your Zoom settings -> Share Screen -> Window size when screen sharing-> Check radio button "Maintain current size" 

This ensures that zoom doesn't resize itself to overtake whatever you are sharing on internal/external monitors. 

Fyi this has worked on Windows & MacOS. Hope it also works for you! 🙂

There are a number of possibilities. However, I would need a lot more information about the screen share content. And VLC is not the best choice to do this especially since you want to show the gallery view on the same screen that has content that is being shared and you want to show the gallery view on the first display as well. It is doable, but the setup is too complex to explain here in a few words. If you would like one-on-one assistance let me know and I can assist you via Zoom. As a broadcast  and A/V engineer this is something I can solve.

So, the issue is not with JW Library or any other applications a user wants to share, it's something with Zoom that seems to be weird with how it handles monitors / dual monitor screens. I have tried from the Hall and from my home setup and it behaves the same way.




The workaround was to disable the setting to allow the host to share the monitors (I personally hate this, and it really limits things). We share the application now and that prevents the zoom window from bouncing displays. JWLibrary now has the ability to play imported images and files that are appropriate without having to go to VLC or OnlyM and it seems to work fine. That lets us keep the dual monitors setting and minimize the Library 2nd screen to display participants if there are any. 

The other workaround probably is to disable the "dual monitors" setting from the video in a meeting, but for those with two or more monitors that also limits things. 

If anyone on Zoom reads this comment the issue is if you have dual monitors enabled, when you select share screen, the "2nd screen" Zoom window gets moved to the screen you are trying to share and thus obstructing the content. 

It looks like one of the newest versions of JWLibrary lets you share the 2nd screen as an application so instead of clicking to share the "screen" you should be able to share the 2nd screen and not have the Zoom window bouncing issue during a meeting. 

Similar to many of the comments in this thread, from my extensive testing, the issue seems to revolve around the "Use dual monitor" option/feature in Zoom.

I've tried all combinations of the Screen Share options (ie. fullscreen mode, maximize window, and maintain current size).

What I've observed is, if you have the "use dual monitors" option enabled, what actually happens when you attempt to share the second screen/monitor, is that Zoom's "second" screen (the one that shows just the participants, not the controls), forcefully shifts back to the first monitor. But, it remains in fullscreen mode/view, and forcefully minimizes all other applications.

I've tested this with other applications (ie. a fullscreen picture in the Windows Photos app), not just JW Library. So the issue truly is with Zoom, how it interacts with the second monitor, and it's participant-only view.

Any news on this problem ?
I had to bounce back to V5.16 to stop zoom changing the size.
If someone accidently runs an update the problem will be back.
Is zoom working on the issue ?

Problem:

When using two screens, sharing the second screen causes the JW Library window to minimize unexpectedly.

Solution:

The issue was resolved by preventing Zoom from starting automatically when Windows boots. The following steps outline the successful procedure:

1. Disable Zoom Auto-Start:

   - Open the Zoom application.

   - Go to `Settings` (usually found by clicking on your profile picture in the top right corner).

   - Navigate to the `General` tab.

   - Uncheck the option `Start Zoom when I start Windows`.

2. Proper Startup Sequence:

   - Restart your computer.

   - Ensure all screens are connected and functioning properly.

   - Manually start the JW Library application.

   - Finally, open the Zoom application.

By following this startup sequence, the problem of applications minimizing on the second screen no longer occurs.

Hi,
This is what has helped us....has not stopped the issue 100% but has reduced how much it happens. This is a Zoom issue seems to be the concensus.
We leave Use Dual Monitors checked.....Before the meeting starts we make sure the 2nd Zoom screen(the one showing the stage and participants) is on the TV's and is maximized. Then in the Taskbar I put my cursor over that 2nd screen thumbnail and when the small preview window appears I slide my cursor up in the preview, right click to get the menu and left click on minimize. The 2nd screen gets pulled back to the Taskbar of the PC monitor. Leave it there until it is time to show that 2nd screen for someone giving a talk on Zoom. When its time for a part over Zoom I remove the spotlight for the stage and I reverse what I did earlier.....slide my cursor over the thumbnail again, slide it onto the preview window, right click to get the menu and left click on Maximize. When that part is over minimize the window again, put stage spotlight on again and click on thumbnail for Year Text.
Now when Zoom decides to take over the 2nd screen, which usually happens during a song, it only shows a black screen and we just quickly click on the JWL thumbnail to bring it back.
With a little practice it can be done very smoothly.

The best solution I found so far is to make sure you never share the projected zoom display (on monitor 2, with the speaker) to zoom.  Display the image you want to share first then share. The image will disappear, you have to reselect it hovering over the JW app selecting the second screen. But then it displays and shares properly. And when you want to go back to the speaker, stop sharing first. The second zoom screen will then pop back to the second monitor (it effectively “got out of the way” temporarily, as others have mentioned).

We have not found any solutions so far. We have tried many of the sugested solutions above, but so far non has helped us. With every update it gets worse😅 

It is comforting to know that we are not alone in this struggle. 

Actually, sometimes  we do not share everything, like pictures that the participants on zoom can see in their own publications. That way the meeting does not "pause" too many times.
