Miracasting

 We have a couple of Microsoft 4k screen adapters

 We have a couple of Microsoft 4k screen adapters.

The problem is that one can not buy any more.

UMART show two adapters.  One of which purports to be 4k

HDMI Dongle Wireless 4K, 5G Miracast HDMI, Stabile HDMI WIFI Miracast, Alta Definizione Adattatore HDMI Wireless for Android/iOS/Windows/etc

Microsoft Display adapter plugged into my 4k TV

(This is my laptop screen showing  display settings.  The laptop os screen 1 and the wireless adapter is display 2)

Umart unit plugged into the same 4k TV

In fact the exact same HDMI input.
But it's a 1080p picture.

Does not even give a 4k option
4k is 3840 x 2160

The best the UMART one will do is 1920x1200

The box says Chromecast and that is a bit sus.  The manual does mention miracast in the context of Android.

The manual does not list windows.  Bit concerning...

Sent a question to UMART.

Suspect that I need to find a different device.

I bought a couple of wireless HDMI interfaces.  
The web site says they are 4k but as far as I can see they are 1080P.
Can you tell me how to get them to transmit a 4k picture?
I put some photos on my blog.
this is the second time I have messages you.  I am looking forward to a response.
