We have received a report from a user who is running Mac Book Pro 13-inch with external 27-inch monitor (both in landscape orientation). When they try to share their screen (call to `getDisplayMedia({ video: { cursor: 'motion', logicalSurface: true }, audio: false})`), only the primary monitor (27-inch) is listed, while the secondary monitor is not listed.

This is by design as we don’t currently have a screen picker. We will consider this need for a future update.

It's worth noticing that they can share any of the two screens, but since there is no screen picker implemented yet, the stream received from getDisplayMedia will be the display in which the browser instance is placed on when calling getDisplayMedia(). So a temporary workaround is simply move the browser window to the screen you want to share before initiating screen sharing.
