I can send my screen from my mobil (android 5) to the tablet (android 6) and from tablet to mobil. Android includes that option by default.

But also have a Google Tv MK808 with Android 4.1.

I'm looking for is a program which I can install on MK808 and send screen from mobil or tablet to MK808.

Tried many programs, but not found... Most allow send video or sound, but not the screen

Any suggestion?
