Samsung LCD monitor connected via DVI
Eiki projector connected via HDMI

In Display | Screen Resolution the Samsung is "currently your main display" but it is identified as Display 2 and is extended to the Eiki which is labeled as Display 1.

I need the Samsung to be 1 and the Eiki to be 2.

I know that in Control Panel\Appearance and Personalization\Display\Screen Resolution I can grab the picture of a display and move it to the right or left of another display. That does not change the display number associated with the monitor or projector.

In the Advanced Settings, I can access the AMD Radeon Catalyst Control Center. In here, I have been able to change the display numbers. However, after the changes are applied and the monitors are correctly identified in the Catalyst Control Center, when I return to Control Panel's Screen Resolution settings, the display numbers have not changed. At this point, Windows and Catalyst Control Center are oppositely numbered. How can I change the numbers associated with the displays?
