I got the MS wireless display adapter for my SB. My TV is 1080p. When I use the adapter to display the contents on the TV or on both devices it works fine. However when I chose "extend on these displays" I encounter major issues. The pointer remains on one display and has trouble going to the other display and the programs that opened on the main display cannot be moved to the secondary display. For example if I open Edge on the main display, I cannot move that window or open another Edge window in the other display. Essentially I cannot move from one display to the other. Does anyone else use a MS wireless display adapter with their SB and can tell me what I'm doing wrong?
