@malcolm the wiki says:
if you click-off the window, you won’t be able to re-enter exclusive mode. You’ll need to leave and re-enter perform mode
In my setup: 1 HD Monitor + 1 (2x4k) Mosaic-Monitor I can open a window in single monitor exclusive mode on the mosaic display, click off that window, and then click on the window again and it seems I am re-entering single monitor exclusive mode. No need to exit and re-enter perform mode
PresentMon reports:
clicked off the perform window
TouchDesigner.exe[16940]: 0000000000000000 (Other): SyncInterval=-1 Flags=0 CPU/Display=16.66/16.67ms (60.0/60.0 fps) latency=38.20ms Composed: Copy with GPU GDI
clicked on the perform window again

Looking at the PresentMon docs (copied below) it seems that LegacyFlip means “exclusive mode”
| PresentMode | Description |
|---|---|
| Hardware: Legacy Flip | Indicates the app took ownership of the screen, and is swapping the displayed surface every frame. |
| Hardware: Legacy Copy to front buffer | Indicates the app took ownership of the screen, and is copying new contents to an already-on-screen surface every frame. |
| Hardware: Independent Flip | Indicates the app does not have ownership of the screen, but is still swapping the displayed surface every frame. |
| Composed: Flip | Indicates the app is windowed, is using flip model swapchains, and is sharing its surfaces with DWM to be composed. |
| Hardware Composed: Independent Flip | Indicates the app is using flip model swapchains, and has been granted a hardware overlay plane. |
| Composed: Copy with GPU GDI | Indicates the app is windowed, and is copying contents into a surface that’s shared with GDI. |
| Composed: Copy with CPU GDI | Indicates the app is windowed, and is copying contents into a dedicated DirectX window surface. GDI contents are stored separately, and are composed together with DX contents by the DWM. |
