Sharing your screen

To start Tuple call, click the "Call" icon to the right of one of your contact's names:

Once you have started a call you'll be able to share your screen by clicking "Share screen":

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":

You'll then 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:

• We 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 share exactly half of your screen, the icons to the right in the menu bar will divide your screen into equal parts.
• 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.

Press "Share Screen" once you are satisfied with your choices. You'll then see the red corners indicating what your pair can see:

If you'd like to change what part of your screen you're sharing, you can opt to "Change Selection" :

If you'd like to share your screen immediately when starting a call, you can hold alt to toggle the call button mode.

When alt is held, the call button will show the option to start a screen sharing call, which will share your screen immediately when your pair answers:

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 Desktop & Dock at the bottom of the page:

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" or by using the quick switcher:

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).
