When having a 1:1 meeting the remote video is displayed in wide screen mode and the local is displayed as picture in picture on the desktop app (this is displayed similar to what you see on the android phone app). When having the same 2 users participate in a scheduled meeting the wide screen setup is lost and you get the square video pictures on a windows desktop machine (android apps behaves similar to the 1:1 still displays wide screen) Cutting back to square picture is a problem if it is a meeting room as you end up seeing a table with coffee cups and laptops and can no longer see the people in the meeting room, there must be a smarter way to display wide screen when it is offered by the camera, plenty of room on the screen.
This is the as-designed behavior of Lync/SfB. Peer calls will defualt to widescreen (16:9) video, but conferences default to a cropped square (1:1) for desktop and mobile clients. Qualifed room systems are programmed to send widescreen on their outbound video (like Skype Room Systems).
If you are building your own customer room systems using the Windows SfB client you can force sending widescreen from those (or any Windows client). Simply uncheck the "Crop and center my video in meetings" setting found under Options > Video Devices > Video Settings in your SfB client.
Exit and restart the SfB client and you'll see the sending video will now always be widescreen regardless of the call type (peer calls and meetings).
