Can you explain the physical connections? Is there an actual dummy monitor hardware device involved? How does one use the Windows display settings to clone the AVR+TV with the dummy monitor?

Just connect the Dr HDMI or MDK to the GPU without a monitor attached. That should show up as another display. The Windows display settings lets you duplicate two displays so it appears as one display with both monitors receiving the same image.
