Matter Casting is an open standard casting protocol that allows users to cast content from their phone to their TV without proprietary hardware. It offers more flexibility than mirroring solutions, such as Apple's AirPlay or Google Cast. Currently, Matter Casting only works with Prime Video on Fire TVs and the Echo Show 15, but more apps are expected to add support in the future.
