Casting From iPhone to Nvidia Shield - Power On (HDMI-CEC) and Play



Up until recently, if I attempted to cast anything from my iPhone to either of my Nvidia Shield TVs (2nd Gen, 16GB) while the TVs were powered off, the play action would wake my TV and play the item selected. Now, the TV is powered on and the item is shown on the screen, but does not play unless I select it a second time once everything is powered on. On the iPhone it shows that it starts to playback, but stops before TV is fully powered on.

This has also affected the use of Alexa to start a movie/show from a powered-down state. It requires two selections or repeating of the same verbal command. One powers everything on, and another starts playback.

We use the casting feature from our phones to start TV shows and Movies in other rooms for our kids. The TVs that have Rokus still work correctly from a powered down state. Also works correctly on our Sony Android TV

I've tried turning off screen saver and tinkered with other settings. I have the Shields set to not fall asleep so that they are visible to the iPhone to cast.

Any help would be appreciated.


I have 3 chromecasts in my house and all 3 have been playing up (similar kind of issue)with regard to plex, I think google have made a change to google cast and plex have not caught up with it.


I guess saying “casting” was probably inaccurate, I mean just playing from the Plex app or from Alexa, not actually casting using Google Chromecast built in. Though, this is probably related.

Any other comments/suggestions?


I think I've figured out why. If you are watching something in Plex on Nvidia Shield (whether you start it from your phone, any other Plex player, or just with a remote) and either turn off the TV or turn it on, it stops the video from playing and kicks you back to the movie/tv show details screen. It does not matter what CEC control settings you have on the TV or the Nvidia Shield or if CEC is completely off. THIS IS A BUG! Turning ON the TV should not stop the playing video...

This is not the behavior that it used to have. Something changed with an update to either Plex or the Android TV version for Shield. I have a couple Roku's and they do not exhibit this behavior. I also have Amazon FireTVs (also Android OS) they do not turn off the video when the TV is turned on, but do stop the video when TV is turned off (which is fine).

This behavior is what is preventing the ability to use Alexa with Plex when a TV is powered off (without repeating the commands). It is also preventing starting a video from your phone if the TV is powered off without repeating the steps. The FireTv does not use HDMI CEC to power on TVs, so its not an option to use it. Only Rokus and Shields do this and Shield is broken b/c of stopping video when TV is powered on.

It's really easy to test. Use phone (or any) Plex app to start a video on a TV that is powered of (as long as Plex is opened on that Shield so it can be "seen" by app. Now power on TV and watch the video stop.

I've realized over the years that it is unlikely to get Plex to comment on this on this forum, but if they or anyone can help or suggest anything, it would be appreciated!

EDIT: I stand corrected regarding the Amazon FireTV and HDMI CEC. It does have it and it works as expected, but not the Shield TV
