I've set pdf documents up for my set list songs that have a completely black background. Yet when I double-tap them to go 'full screen', I invariably get a white border on two adjacent sides: top and left or right and bottom. I've changed the size of the pdf (I'm using Word pages printed to pdf format) but to no avail. Any help would be appreciated.

On iOS, this shouldn't happen because the document viewer can't invert the document colors. On Android, if you created documents with inverted colors and then you turn off the color inverting in BandHelper and you get a white border around the black document, you can turn on Help > Utilities > PDFs are Already Inverted.
