The developer working on integrating network display functionality into GNOME Shell shared short video clip to the GNOME sub-reddit […] the feature adds a “screencast” button to the row of actions in the Quick Settings menu. Clicking this opens a modal picker where the user can select any Miracast or Chromecast compatible displays on the network.
Tried “GNOME Network Displays” from flathub previously, couldn’t get it connected to my TV and I wish it had option to cast a specific window. Hoping it will be smoother experience when it’s integrated into GNOME
