Share a single screen/monitor in a multi-monitor setup

Is your feature request related to a problem you are facing?
I have too many monitors. I only get the option to share the entire workspace which has all monitors included or individual windows. People can't see very well what I am showing if they have a small screen.

Describe the solution you'd like
It would be really nice to be able to share a single monitor.

Describe alternatives you've considered
I tried sharing individual windows but it is not practical to keep having to switch between them.

This issue is similar to #3969. Would I need to post this at https://github.com/jitsi/jitsi-meet-electron ?

+1 to this idea.

Distribution: Ubuntu
Desktop Environment: GNOME
Package: running straight from http://meet.jit.si
Browser: Firefox

Is your feature request related to a problem you are facing?
As a dual monitor user I deliver many online presentations. I use one monitor to deliver the presentation and use the second monitor to manage the presentation (eg using google slide sof MS Powerpoint), speaker notes, other apps or views to pull into the presentation.

Currently I am limited to a specific application or all dual screen contents. It would be nice to constrain to a single monitor including all apps on that monitor.

It would also be nice to be able to share the actual jitsi application so I can take new users on a tour.

Describe the solution you'd like
When being asked for screen sharing permissions I would like to select screen#1 and Screen#2 as my left and right monitors.

Describe alternatives you've considered

• I tried sharing individual windows but it is not practical to keep having to switch between them. One example is when I run demos I use google slides to start off and then might move to another browser window. I then need to unshare and re-share. During this process my users must experience a dizzying mass of cascading windows on their screen.
• A dirty workaround hack was posted here, but looks complicated: https://github.com/Ashark/hliss
• chromium might have had a fix, but is only working in their daily build: issue https://bugs.chromium.org/p/chromium/issues/detail?id=396091#c39 daily build: https://download-chromium.appspot.com/
• tried out the latest chromium daily build. result? PASSED (see issue and link above)

Implementation Details:

• according to Feature request: Share a single screen #3969 this might also be related to browser functionality.
• About the screen capture API in Firefox: https://developer.mozilla.org/en-US/docs/Web/API/Screen_Capture_API/Using_Screen_Capture
• About Web RTC API for firefox: https://developer.mozilla.org/en-US/docs/Web/API/WebRTC_API
• Good comparison chart for media capture and streams API for various browsers: https://developer.mozilla.org/en-US/docs/Web/API/Media_Streams_API
• If Jitsi is reliant on Firefox's implementation of WebRTC API and the appropriate hooks for the already supported physical/logical displays is not possible then perhaps implementing a firefox extension to select sharing a single screen might be possible. https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions

I think this should be closed. The new version of jitsi-meet-electron seems to have this bug fixed. It worked for me for a while already.
