Recently, I was working for a new client. When I logged into Ax, the font sizes seemed uncomfortably small. The major problem, however, was that an SSRS report that I was working on had major presentation issues (fields cut off, sections not appearing, etc.). When I exported the report to PDF (for once), the presentation was fine. So, I decided to see if I could adjust the resolution of Ax to see if that was the problem. Turned out it was.
