That works for me with an old Samsung Note 10.1. easily.
With a newer Samsung Galaxy S4 mini duo it does not work!
With a Samsung Galaxy S3 Mini, it does not work out.
(Samsung calls its Miracast-based method: ScreenMirroring and AllShare)
Both mobile phones have it, the latest operating system Android.
I was hoping that one also with a WiDi (Wireless Display) can connect tauglichem Win 7 laptop this dongle. Here I come, after several days around bungle to the conclusion that this is not possible.
Intel WiDi is based on Mircast and Win 8 and 8.1 WiDi is even integrated, but unfortunately WiDi used yet another connection method !. Although my Win 7 laptop finds the dongle, but can not fully connect to, because it expects a password (EIDI) from Dongel ... to this, as a pure Miracast device but does not send ...
The dongle is generally well made, and easy to connect. But the manual is insufficient short and documented, for example, not even that you can reach the dongle via a web interface and can switch from here Miracast on DLNA.
He is also, for example, iOS compatible. But since I do not own iOS device I could not try it.
In general, the screencast technology is still very new. Miracast has the potential BS-independent standard to be present but not every manufacturer tries to bring his own thing on the market shall designate partly the same thing with different names and murkst with own method around ...
My tip: punish industry and not buy until the marketing ***** to a uniform system HAVE AGREED!
