• I had to cast something to my Display system, from my phone to show multiple people, and instead of casting to the Samsung I sent it instead to the Roku Ultra 2024 in our theatre.  
  Now because all the sources (5) feed a Yamaha Dolby System, that then feeds the Samsung,  Casting to Samsung involves muting the Yahama Dolby system and also increasing speaker level on Samsung. 
  
  

Now I had seen casting settings in Roku Setup Menus, but I had never set anything.  So I was not expecting much in the way of success. 

Surprise…. Surprise!!!!  IT WORKED FLAWLESSLY!!! Nary one dropped frame or audio issue!!!

And I did absolutely no prior settings for it!!

One ATTA BOY for Roku!
