Isn't Miracast supported on UBOOK X?


I’m an UBOOK X user.
I tried to use it for sub-display but there seems no “Connect” app, no “Projection on this PC” in config menu, either.
Maybe Miracast isn’t supported on it.

I’d like to know alternative way to use my tablet as sub-display, if there is.
Or is any cable device required to do it?

Thank you.
