Hi…I’m trying to screen mirror my phone/laptop to my smart TV, but I’m not really sure how to do it. I know it’s possible, but I’m a bit lost on where to start. What’s the easiest way to get this set up? Are there specific apps or settings I should use depending on the device? Also, do I need any special cables or adapters, or can I do it wirelessly?
Any advice or step-by-step instructions would be greatly appreciated. Thanks in advance for your help 
Assume that both your Android smartphone and smart TV are linked to the same Wi-Fi network in order to mirror your screen. Navigate to the ‘Cast Screen’ or ‘Screen Mirroring’ menu on your TV and choose your Android device.
I use the iPhone app to screen mirror to my Samsung tv. Tv connect with my home network with WiFi. And also I have an android box - and it’s work too. For all this technology need good WiFi signal.
If your phone does not have screen mirroring built in (mine didn’t) there is an app to add it. Downloaded Miricast app and I can now screen mirror the screen to anything supporting cast.
