Based on the Zoom documentation noted at the beginning of this story, the web client does not support dual monitors. Note: We tested this on the latest desktop client for Windows 10, not the web client. To avoid and disable this vulnerability, disable the ability in the Zoom settings / preferences for Zoom to turn on your webcam when joining a meeting. The second thing you should do is set up Zoom for dual-monitor support. If you don’t want PowerPoint to fill the second screen by default, change the Monitor Option from Automatic to your Primary Monitor, which is typically your laptop’s display. This mode of use is also handy if you want to have other applications visible on the second display while giving a streaming presentation.

Once you’ve done this, it will effectively make PowerPoint act as though you have only a single display. The Primary Monitor is typically the laptop’s display. Click Select the Monitor and choose your primary display from the drop-down menu. In our experience, PowerPoint still automatically tried to use the second display, but you can further limit it by using the Monitor option. I've tried the following but none of them worked.

But currently I have facing some problems trying to disable pinch zooming on every browser I've tried. On a dual-screen setup, PowerPoint 365 will automatically select Use Presenter View. I hooked up a LG 23ET63 multi-touch monitor to my windows pc Windows 10 looking to run a site on Chrome in kiosk mode.
