Open the Storage drawer, see the monitors drawer, open monitors drawer.
See all the options? Great.
Open the DEVS drawer, see monitors drawer...
Drag and drop the newer monitors options from the Storage/monitors drawer you want to the Devs/monitors drawer.
Open the Prefs drawer, open the screenmode icon. See more options?
You can test which work for you by just double clicking the icons in the Storage/monitors drawer and then testing in screenmode but to make the new monitor stay, you have to drag (or copy) it over.
