Further update. Using a plugin from Low Entry that has a screen size command I has a marginal response. I also recorded a video of the project in action. I can see that the project first goes to a full screen, black screen with no border. Then it shrinks (hopefully to the size I specified but it seems suspiciously smaller) to a small square black box on the top left of the monitor. Finally it re-expands to full screen as soon as the viewport initializes. I even placed the resize command AFTER I added my widget to the viewport. I have the project and video available if needed.
