To redefine the resolution, the required mode can be selected manually, for example, 720p (HD) or 1024p (FullHD); the presentation will then be sent to the server with the selected resolution.

The program will remember this choice and will apply it in the future. To return to automatic selection of the sent resolution depending on the source, select “Auto” mode again.

“Use system sound” is the checkbox that when used turns off the desktop sound and sends sound from the presentation source to the conference thus making it possible to start a screen demonstration and open, for example, a video on YouTube. The receiving party will hear the sound of this video.

Limitation: using system sound is only available for Windows 10.

The indicator that the screen is being shared is the window at the bottom of the screen.

Screen sharing can be ended by clicking the “Stop” button.
