  1. No. Mirroring doesn’t work on my chromecast on either windows10/chrome nor android/lg5. all on the latest revs. all other mirroring works, black screen when hbo max showing on a tab or phone screen. one of them or both….low quality.

  2. I got lost after the screen mirroring devices step (the 2 steps after that) There isn’t an option to connect devices on the iPhone(Xs). I did go to Settings->Bluetooth to check for connection but no new ones appear. I’m trying to mirror from iPhone to Roku streaming device (Ultra LT). TIA

  3. I get SOUND only and no video. ONLY with HBO max shows. I get SOUND and VIDEO when its HBO previews. But actual shows on HBO Max via either Roku Mirroring or Chromecast Mirroring? Nothing. Netflix works. Everything else works. But ONLY HBO Max gives me SOUND only and NO video for actual HBO shows.

  4. I’m having the same issue as above. Previews cast with picture and sound, but when I start a show it is only sound. Ugh what is the deal with this! Everything else casts just fine from my phone. And I can watch all the previews just fine from HBO.

  5. I’ve tried using the Windows built-in screen mirroring (Cast to wireless display) and it works for everything but HBOMax. I can login and start playing a video on the website as long as the browser is on my laptop’s screen. But as soon as I drag the window to the TV (connected through my Roku) the video stops playing and gets an error.

    I think HBO is using some form of trusted display path lock, which Windows supports, and its preventing streaming to any device not physically connected to the computer. This is why I can stream through an HDMI cable to the TV.

  6. I have HAD IT! We’ve been casting with Chromecast for 3 years and all of a sudden it just doesn’t cast my HBO MAX anymore. Tired of spending $15 a month for services that just DO NOT WORK! If this isn’t resolved by the end of the month, I will drop HBO MAX. My google device refuses to cast my shows, saying I don’t have HULU…no, I pay for HBO MAX and it should WORK!!! I’m angry!

  7. Casting hbo max worked fine for me a month ago. Now I get a yellow and black grid across the screen whenever I try to watch something. I am not going to continue to pay for a subscription to only be able to watch this on my phone. Please fix this HBO!
