The FireTV 4k does support Miracast out of the box.
I could use Windows+P on my Windows 10 laptop and use the FireTV 4k as secondary display, ether clone, extend or use only this display.
I can't do this with the Chromecast with Google TV or the Shield TV 2019 which are both Android TV devices. Do I need a special app to make that working properly? Does anyone have experience with that?
I know about the possibility to "stream my desktop" via google Chrome, but it's not the same. You can't extend your desktop that way.
I know that there are Android apps which bring this function. I am just asking if I somehow miss the integrated feature or if someone has a recommendation (as there seem to be thousands of apps for that).
Thank you!
Hey, i use it all the time and you can extend your desktop.
I first press windows + P and select extend. After that I go to chrome and cast my full screen. It will then ask which display to cast. Select the 2nd screen and it will work just like it would with miracast.
