If you are using the Duet Display app on your iPad (iPad Pro, iPad Mini, etc.), you may have noticed that the display is not full screen. There is a black bar on the bottom of the screen and the app does not use the full aspect ratio of the iPad. If you are experiencing this issue, we have found a workaround that will remove the black bar and allow full screen on Duet Display on your iPad.
