Depending on the display driver selected, each viewport contains a series of up to five menus in the top left hand corner that control viewport display.
The menus are:
- General
- Point-of-View (POV)
- Shading
- Per-View Preference (Nitrous only)
- 2D Pan Zoom (displayed only in 2D Pan Zoom mode)
Click or right-click a menu to view its specific options.
