PDF annotate app with no sidebars from underscan
I use my IPad Pro and when I display my image using HDMI or VGA using a projector, I get black sidebars on the left and right side due to underscan.
Is there a PDF annotation app that will automatically compensation for the change in aspect ratio? (Like the Apple photos).
I have tried PDF expert, noteshelf and adobe reader without success.
The projector is often fixed in the ceiling in the classroom and I do not have access to change the zoom/keystone on the projector itself.
There must be others that have experienced this, and I am hoping there is a solution.
iPad Pro, iOS 13
