iPad Air M1 Using External Monitor Only Allows Mirroring.

My iPad Air M1, when I am using an external monitor, only allows me to mirror the display. iPad is updated, Stage Manager turned on, the second display connected either through a hub or directly via HDMI to USB-C cable. It mirrors just fine, but doesn't allow an option to adjust position or extend the display.

Your monitor’s screen resolution will impact the available settings and external screen capabilities. 


While undocumented, testing has demonstrated that 4:3 monitors with a display resolution of 1280x1024 and below are currently only usable with iPad screen mirroring; as such, associated settings to disable screen mirroring in favour of Stage Manager are not available in iPad Display settings.


When used with a 16:9 widescreen monitor, with a native display resolution of 1920x1080 or greater, the full set of Display settings - and access to Stage Manager - become available.


The iPad User Guide lists the upper resolution limit as 6K - but the Guide offers no lower limit, or suggestion of aspect-ratio, being a factor for compatibility:

In conclusion, your monitor must be capable of 16:9 widescreen 1920x1080 (FHD) or greater to support iPadOS16 Stage Manager extended desktop. Unless the monitor meets the minimum required specifications, you will not see the full range of controls in iPad settings.  


When mirroring your iPad display to an external monitor, expect to see black bars to infill where the iPad screen doesn’t match the aspect ratio of monitor screen.


Whether or not this is an intentional limitation, or a bug introduced with release of iPadOS 16.4.1/16.5, is unknown.
