Techniques are presented herein to enable a first device participating in a conference session to adapt its displayed content being shared from a second device that has a larger display and can therefore display a larger area of content than the first device is capable of displaying. The first device has a first display and displays a portion of content being displayed on a second display of the second device that is being shared with the first device during an online conference session. The first device detects when a first change has occurred in the content that is outside of the portion displayed on the first display. A graphical element is displayed on the first display, the graphical element indicating that the first change has occurred in the content outside of the portion being displayed on the first device.
