I'm developing a program to display my sheet music on a Windows tablet (Microsoft Surface). The PDFs contain only one page, and I generate them myself using Word. The issue is that when viewing the PDF in full screen using PdfRenderer, it does not completely fill the display. The PDF page is rendered with page borders, and around the rendered page, there is additional empty space, making the PDF content appear smaller than the available display space.

I want to make full use of the display by eliminating both the page border and the extra empty space that appears around it. I have tried setting Padding and Margin to zero, but that does not solve the problem. How can I achieve this?

I have attached an image showing the top part of the screen as it currently displays the PDF.

Thanks!
