RDP server Use SR-IOV VideoAdapter Client can't display.

Your Windows 10 VM accepts RDP until “Use hardware graphics adapters for all Remote Desktop Services sessions” is enabled; with the Intel UHD SR-IOV adapter, the client opens a black window. Microsoft documents that this policy switches RDP from the Microsoft Basic Render Driver to the hardware renderer, isolating the failure to the virtual GPU and RDP graphics path rather than connectivity. Set the policy to Disabled and restart the VM. If the session returns, keep software rendering until the GPU path is validated. Check the SR-IOV adapter in Device Manager and install vendor-supported host and guest graphics drivers. If hardware rendering is required, reproduce on a supported Windows guest and capture the Windows build, Intel driver versions, hypervisor configuration, and RDP event logs for Microsoft or vendor support. Microsoft’s GPU-partitioning guidance applies to Server 2025, so it does not establish that this Windows 10 Intel UHD configuration is supported.
