My airplay with video works infrequently. The audio from my iPhone works consistently to mirror on my TV, but the video does not. I get error messages saying that it could not connect to the TV... though the sound is connected.
@tsambroise68: Are you attempting to mirror a particular streaming app, such as Netflix, or are you mirroring video files downloaded from another source? If you head to Home > Source > Connection Guide > Smartphone > Airplay, this will walk you through the necessary connection steps. For additional settings, head to Home > Settings > General > Apple Airplay Settings. I'd also recommend checking for any available updates for the TV by heading to Settings > Support > Software Update > Update Now.
Figured it out, I had my tv connected via Ethernet cable, with this connection only sound will stream switched network setting to wireless and now airplay plays both sound and video
