How can I use the ClickShare Dual Sharing feature

This article explains using the ClickShare Dual Sharing feature through the ClickShare Desktop App. This functionality enables the user to simultaneously share two different pieces of content from their laptop to two displays connected to the ClickShare device. The article also covers various scenarios in which this feature can be effectively utilized. Each scenario includes a separate procedure to be followed for ClickShare Desktop App version 4.41 and higher, and for version 4.40 respectively.

Prerequisites for the ClickShare Dual Sharing feature:

1. ClickShare Desktop App version 4.40 or higher installed.
   Ensure that the new user interface is selected on the ClickShare Desktop App.
2. ClickShare Conference CX-50 Gen2 or ClickShare Bar Pro.
   Ensure that the firmware version 2.20 or newer is running on both.
   To be noted, dual cursor support is available starting from version 2.21.
3. Dual displays connected to the ClickShare device.
4. Set the display mode to Extended (default setup).
   For how-to instructions, see KB 7868 (for CX-50 Gen2) and KB 12624 (for CB Pro).
5. Windows 10 and 11 or Mac.
   
   

Scenarios for the ClickShare Dual Sharing feature:

• Scenario 1: Single user sharing two different contents from their laptop
• Scenario 2: Two users are sharing content from their laptops
• Scenario 3: Sharing content using ClickShare Dual Sharing feature in a Microsoft Teams or Zoom meeting
  
  

Scenario 1:  Single user sharing two different contents from their laptop

This procedure can be followed by a user in a meeting wishing to share two different contents from their laptop, with each content being displayed separately on dual displays connected to the ClickShare. By "single user", we are referring to you as the user.

ClickShare Desktop App version 4.41 and higher

1. Launch the ClickShare Desktop App, navigate to the first content thumbnail and click on the thumbnail to share it to the dual display.
   The shared content is duplicated and displayed side by side on both connected displays.
2. Navigate to the second content thumbnail you want to share. You’ll see a + icon will appear within the thumbnail.
   
   
   
   
3. Click on the + icon on the second content thumbnail to share it to the dual display. Hovering over the + icon will result in it being highlighted against a white circular background.
   
   
   
   This action will replace the first content with the second content on one display. Afterward, the first content will be shown on one display, while the second content will be shown on second display.
   
   
4. At this stage, if you want to share a new content (i.e. third content), clicking on its thumbnail will display a message “Click and hold to take over” on the ClickShare Desktop App interface.
   
   
   
   To share a new content you can do one of the following:
   • Unshare one of the currently shared content by clicking the red-square  stop button within its thumbnail, then navigate to the new content thumbnail and click the + icon within it to share it.
   • Long click on the new content thumbnail to replace both of the currently shared content on both displays with the new content.
     
     
   Note: At this stage, if a new user (for example, User 2) wants to share content. They just need to click on the content thumbnail on the ClickShare Desktop App interface. User 2 content will replace one of User 1 shared contents on one of the displays.
   

ClickShare Desktop App version 4.40

 
Example: representational image only

1. Launch the ClickShare Desktop App and navigate to the the thumbnail of the first content you wish to share.
2. Click the "Side by side" button on the thumbnail of the first content.
   The selected content will be displayed on both connected displays side by side.
3. Navigate to the thumbnail of the second content you wish to share and then click the "Side by side" button. 
   This action will replace the first content with the second content on one display. Afterward, the first content will be shown on one display, while the second content will be shown on second display.
4. If you want to share a new (i.e. third) content, you can either unshare one of the currently shared contents or click the "Take over display" button. Attempting to share the third content by clicking the "Side by Side" button on its thumbnail will not work and will display the following message on the ClickShare Desktop App.
   
   Unsharing a shared content:
   
   
   1. In the ClickShare Desktop App interface, navigate to the thumbnail of the content that is currently being shared on the display.
   2. Click the "Unshare" button. The selected content will be removed from the display where it is currently displayed.
   3. Navigate to the thumbnail of the third content and click the "Side by side" button. The new content will be displayed on one display.
   
   Clicking the "Take over display" button:
   
   
   1. In the ClickShare Desktop App interface, navigate to the thumbnail of the third content.
   2. Click the "Take over display" button. The content currently displayed on both displays will be replaced by the third content on both displays.
      
      
5. At this stage, if a new user (for example, User 2) wishes to share its content, it will have two options: clicking the "Side by side" or the "Take over display" button. The usability of these options for new user will depend on the total number of contents you are currently sharing.
   
   • Only one content is shared: Use "Side by side" or "Take over display" button.
   • Two contents are shared: Use "Take over display" button.

   Note: For detailed information on how two users can use the ClickShare Dual Sharing feature in a meeting, see here.
   
   

Scenario 2: Two users are sharing content from their laptops

This procedure can be followed by users in a meeting who want their shared content to be displayed separately on dual displays connected to the ClickShare. By 'two users', we are referring to 'User 1' (you) and 'User 2' (another individual user).

ClickShare Desktop App version 4.41 and higher

1. User 1 and User 2 shared their content by clicking on the corresponding thumbnail on their respective ClickShare Desktop App interface. Depending on which user shared their content first, the following will be observed on the connected displays: 
   • If User 1 shared first, their content will initially appear on both displays, then User 2's content will replace User 1's on one display, and finally, User 1's and User 2's content will be shown separately on each display.
   • If User 2 shared first, their content will initially appear on both displays, then User 1's content will replace User 2's on one display, and finally, User 1's and User 2's content will be shown separately on each display.
2. If User 1 or User 2 wants to share new content, they simply need to click on the new content thumbnail in their ClickShare Desktop App interface. This will replace their currently shared content with the newly selected content.
   Note: If either User 1 or User 2 attempts to share new content by clicking the + icon on the new content thumbnail, a notification message “Click and hold to take over” will appear on their computer desktop. The + icon within the thumbnail and the notification message will only be appearing if you are connected to a ClickShare device running firmware version 2.21. 
   
    
   
   Note: If User 1 or User 2 performs a long click on the new content thumbnail in their ClickShare Desktop App interface, it will replace both users' currently shared content on both displays with the newly selected content.
3. At this stage, if a new user (for example, User 3) wants to share their content, they need to long click on the content thumbnail in their ClickShare Desktop App interface. This action will replace the content currently shared by both users on both displays with their own content.
   Note: If the connected ClickShare device is running firmware version 2.21, the notification message “Click and hold to take over” will appear on user's computer desktop. 

ClickShare Desktop App version 4.40
