Hi Brian Vasquez,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
To enable multi-monitor support in Azure Virtual Desktop (AVD), you need to use the Windows Desktop client. Please download and install the Windows Desktop AVD client and follow the steps below to configure multi-monitor:
Right-click on the Cloud PC icon and select Settings.
Toggle the Use default settings button to the OFF position.
Under Display Settings, select your preferred display configuration from the dropdown (Select Displays / All Displays / Single Display).
Make sure you are using the 64-bit version of the Microsoft Remote Desktop Client, as recommended on the Windows 365 client webpage.
