First the background scenario:

- Our system has 3 monitors and 1 projector connected to an NVIDIA GFX 3070 card
- We use "Remote for Slides" to provide the presenter with a slide "clicker" via their phone
- On the vMix side, the Google slides are placed in full screen on a display
- The slides are brought into vMix via a Browser input (using GDI)
- the display is a virtual display using the Windows Indirect Display Driver provided (free) from AmyUni Technologies (see https://www.amyuni.com/forum/viewtopic.php?t=3030)

That scenario works well for us - we use MultiMonitorTool to move app windows among displays/monitors

The issue we're having is with the vMix Fullscreen functionality. The virtual display is tagged (by Windows) as Display 5 and our projector is tagged as Display 4. There are two issues:

1. vMix only provides the ability to select displays 1-4
2. When we select Display 4 (the projector), vMix shows the Program output on Display 5

Any advice/suggestions would be appreciated. And no, we are not able to use two computers

Update:
- I tried connecting the Projector to each of the graphic card ports. In all cases, the Fullscreen does not appear on the Projector.

- This is a serious problem for us since we use the Fullscreen in our production. Do I file a bug?
