Hello. I got weird behaviour when connecting to a host with two displays. The controller correctly senses the two display, the first one (primary) works fine but when I switch to the secondary I got again the primary screen but mirrored. I have noted that the "mirrored" image would be the secondary monitor but I don't see it as the image from the primary monitor kind of overlays it (but the mouse does act on the icons of the secondary monitor of the host).
So in short I can't remotely control the secondary monitor of the host. Any clues?
