Mirroring your device's screen to your TV does not work.

Unfortunately, SmartTV browsers are not supported for our Live Webcast Streams.

On Samsung or LG SmartTVs you can use your Mac or iOS device to Airplay to the AppleTV+ app on your TV.

Install the AppleTV+ app on your TV. Then, launch the Livestream from your Stash using the LivePhish iOS app or Safari on Mac from  your My Stash page. Then click the Airplay button and select your TV to Airplay to. 

Unfortunately, we do not have apps for Roku, AndroidTV or FireOS at this time. Click the following links for mirroring instructions to those devices: Roku - AndroidTV - FireOS
