What kind of resolution is 1920x1280?
On a 4k Laptop I can select a 1920x1280 resolution for main screen.
On a normal Laptop I can select this resolution when I extend my screen to a 4k screen.
I see this resolution also when I do miracast and when the sink uses the wfd2 protocol.
The strange thing is that the sink doesn't provide this resolution and such a resolution is not
specified in the wfd2 protocol. And windows also returns no optimal video
format in the M4 response message (wfd2-video-formats).
And now the realy strange thing. When I do miracast MICE and the laptop is connected via LAN to the
network. Windows sends a teardown after view seconds when we move the mouse over the screen...
Here the different tests I have done:
standard miracast via P2P --> no teardown
miracast MICE over WIFI interface --> no teardown
miracast MICE over LAN interface --> teardown when moving the mouse
miracast MICE over LAN interface --> no teardown when we don't move the mouse
