Hi Erhard,
So you can't select "Structured Light Setup"???

This option should ALWAYS be there, even when only one screen is available. DAVID does not check whether a projector is connected. Also it does not matter which model, DAVID does not even know. It only sees the NUMBER of display devices ("Monitor ID"). DAVID can't tell between a monitor and a projector, they are all "screens".
Maybe it helps to select another type (hand-held), then go back to "Structured Light Setup".
If something is broken in DAVID's settings, please delete all files in "Settings" to reset everything.
