Zoom has both a screen sharing feature and the ability to control another person's screen, as do some other video conferencing applications. Given that, you might be wondering whether you need remote access software. And you still may. For one thing, remote access software allows for unattended access, meaning you can connect to another computer even if there's no one sitting at it. Zoom can’t do that—you need to be on a call to start sharing. A second problem with Zoom in this context is performance. Zoom's screen sharing feature works well, but they show more lag time than the apps mentioned here.
