It sounds like you can get the screen to display you want in the new system.
Therefore, I would suggest that you try this in the new system:
Turn on Developer Mode
Launch the screen,
Change the size and location to how you want it.
From the Tools menu select Save Layouts,
From the Tools menu select Customization,
Once in Customization mode recompile and save.
Close out of the Customization and the screen.
Turn off Developer Mode
Restart the screen
You should be all set. You may need to get rid of any personalization on the screen's customization first.
