Chromecast 4K Problem

I’m using a Roon Rock as a server which is connected via USB to my Denafrips Ares DAC.

I was using an original Google Chromecast which displayed photos and lyrics from Roon without any problems. After I upgraded the Chromecast to the latest model which is 4K I can’t get Roon to display on the TCL 4K.

Hi @Ed_Incleve ,

Does the Chromecast appear in Settings > Displays at all?

If not, is this Chromecast connected to the network any differently than the previous Chromecast?
