You can work on a full screen in NX. To change the graphics window to full-screen press “Alt+Enter” at the same time on the keyboard or click on the “Full Screen” icon on top-right of the ribbon bar shown in the figure.
In the older versions, the ribbon bar was placed on the bottom of the graphics window. But with the new version, you might have problems to see the ribbon bar on the full screen. If you want to see the ribbon bar on the full-screen mode, right-click on the ribbon bar and click the “Undock Ribbon” or “Dock Ribbon” from the opened list.
