How Many Displays Can The ETCnomad Dongle Support?

Symptoms/Issue

I have several monitors connected to my computer where the ETCnomad dongle is inserted. Is there a limitation on how many different displays ETCnomad can handle? 

Description

The maximum number of computer displays for ETCnomad is 6.  When Fullscreen Offline Editor is Enabled, Eos will be displayed across all available monitors.  When it is disabled, each Eos screen displays in its own window, each of which can be resized or minimized independently.

These settings are specified in the Shell at Settings > General:

Note that ETCnomad will not display on unsupported monitors. This is also true of touchscreens.
