On trusted home networks, Windows automatically detects suitable Play To devices, such as TVs and network-connected speakers. If your device isn't listed on the Devices page, it might not be compatible with Windows.
To check if your connected device is compatible, swipe in from the right edge of the screen (or if you're using a mouse, point to the top-right corner of the screen and move the mouse pointer down), tap or click Settings, tap or click Change PC Settings, then tap or click Devices.
Devices that have a "Not Windows certified" label on them aren't compatible with Play To from video, photo and music apps. However, you can use those devices with Play To from the Music Tools, Picture Tools or Video Tools tabs in File Explorer.
