I have no idea how or why this started happening however my monitors would go black after 15 seconds of idle.  No power settings or screensavers were causing it, nor did I see any helpful logs to help troubleshoot.  However somewhere/how the Energy Star features of my monitor got enabled and literally after 15 seconds of idle time the monitors would go black..

Simple fix:

This fixed the issue not only for the current logged in session but also after a reboot.

Open the PDF file in LibreOffice Draw and once opened, it appears you can edit nearly everything.
