I use my ipad Air with the logitech folio touch keyboard case on a daily basis at work hooked up to a monitor to extend my display. All of a sudden a couple of weeks the display started to only mirror my display with no option in my display settings to extend or turn off the mirror display settings. I have never had any issues related to this before.
