Sharing your screen
To start a screen sharing pairing session, click the screen icon to the right of one of your contact's names to initiate a Tuple call. Once they accept the call, you'll be sharing your screen:
Note: You'll only be able to start a call if the user is online and available (indicated by a green dot next to their avatar).
Sharing part of your screen
To start a call sharing only part of your screen, right-click (or Control-click) on your contact's name:
If you're already on a call, you can share part of your screen by selecting the sub-option "Share Part of Screen":
Once you choose to share part of your screen, you'll see a dotted line indicating which part of the screen you're about to share. You can drag the handles of the rectangle to change its size, or drag the rectangle itself to move it around your screen:
If you'd like to share exactly half of your screen, these icons in the menu bar will divide your screen into equal parts:
We also provide preset sizes for some common screen aspect ratios, in case you'd like to optimize your sharing area to fit your pair's display exactly:
If you'd like to change the size of your sharing area without changing its dimensions, you can hold Shift and drag the corner handle:
When you're ready to pair, click "Share Screen":
After your pair picks up, your screen will show the corners of the sharing area in red:
Choosing which display to share
If you have multiple displays and choose to start a call with screen sharing, Tuple will prompt you to pick one before the call starts. Just click anywhere on the display you want to share:
If you're not seeing a menu bar on your external display at all, check that you have the "Displays have separate Spaces" setting enabled in Mission Control:
Changing displayed screens during a call
If you're already sharing a display but want to switch to a different one, you can swap to a specific display by opening the Tuple app menu and clicking "Switch Screen":
Changing which call participant is sharing their screen
If another call participant is sharing their screen, you can swap to sharing your screen by opening the Tuple app menu and clicking "Share Screen":
Stopping sharing your screen
When you would like to stop sharing your screen, you can stop by opening the Tuple app menu and clicking "Stop Sharing":
If you're currently sharing an external display screen, you'll need to move your mouse to that display, and open the Tuple app menu on that specific display to see the "Stop Sharing" button.
Alternatively, you can find the ability to stop sharing any screen in the drop down from the Tuple app menu:
Note: To access the Tuple app menu on an external monitor, you will also need to have "displays have separate spaces" enabled (see Changing displayed screens during a call above).
