A Microsoft desktop and app virtualization service that runs on Azure. Previously known as Windows Virtual Desktop.
Thanks for sharing your issue with the Azure Virtual Desktop (AVD) Windows app screen settings.
This is a known limitation where the Windows App does not consistently apply single or multi-display preferences for personal desktops, even when the host pool is configured to support multiple displays. In contrast, the Remote Desktop client reliably respects these settings, dynamically adjusting based on the configuration selected in the app.
- Ensure your host pool display settings align with your expected display mode (single or multi-display) in the Azure Portal.
- In the Windows app, disabling the “Fit session to window” option often prevents forced use of all monitors when a single display is preferred.
- Checking and adjusting RDP properties related to display and resolution can also help

- Make sure you are using the latest version of the AVD client.
