No, You have to buy the screens separately.
You can also use smaller size screens, and/or any screen you fancy.
If you would put Nuage on a table (see my picture), then the screens can stand just in front of Nuage, and it will all fit perfectly.
So no special arms or any kind of rocket science is in order here. Of course, you can use such arms …)
The desks from Argosy and a few other manufacturers are equiped to accomodate the screens, but we have chosen to build our own desk. (Although we have Agosy Consoles in all rooms and are very happy with them)
