You can customize your viewport layout, viewport rendering, display performance, as well as how objects are displayed by changing general configuration settings.
When multiple viewports are visible, one viewport, marked with a highlighted border, is always active. This is where commands and other actions take effect. For example, press Alt+W to toggle between maximizing the active viewport and viewing all available viewports.
Only one viewport at a time can be active. Other viewports are for observation only; unless disabled, they simultaneously track actions taken in the active viewport. When Auto Key or Set Key is on, the active viewport border changes to red.
In general, a viewport becomes active as you work in it. You can move an object in one viewport, and then drag the same object in another viewport to continue the move. To activate a viewport without changing the selection, right-click it. If you left-click a viewport, the viewport is activated and whatever you click is selected, or, if you click an empty area, everything is deselected. You can restore previous selections with Undo (Ctrl+Z).
When a multi-viewport layout is active and a viewport is maximized (toggle with Alt+W), you can switch to other viewports in the layout by first pressing and holding the Windows key (sometimes labeled "Start") and then pressing and releasing the Shift key. This opens an overlay interface for switching to a different viewport:

At this point, the next available viewport is highlighted. You can change the highlighting by pressing Shift repeatedly; releasing the key at any time maximizes the highlighted viewport. Alternatively, point to the desired viewport and click the mouse button.
You can resize the four viewports so they are of unequal proportions. To do so, drag the intersection of two, three, or four viewports, on the splitter bars. To return to the original layout, right-click an intersection of the dividing lines and choose Reset Layout from the right-click menu.
The new viewport proportions are saved in the scene. However, changing the viewport layout always resets them.
The three-color world-space tripod is visible in the lower-left corner of each viewport. The colors correspond to the three axes of world space: red=X, green=Y, and blue=Z. The axes are labeled in these same colors. The tripod always refers to world space, regardless of the current reference coordinate system.
The world-space tripod is on by default. To turn off this feature, see “To turn off the world-space tripod in all viewports” in the following procedures.
When you’re working with objects in a viewport and pause the cursor over any unselected object, a tooltip appears with the name of that object. If you need to select something or link to something, wait until you see the tooltip to be sure you have selected the object you want. These tooltips are disabled when you work in sub-object mode.
Tooltips are on by default. To turn off this feature, see To turn off object name tooltips, below. For more information see Viewport Navigation and The 3ds Max Window.
To make a viewport active, do one of the following:
If you click an object in the viewport, it is selected. If you click a space where there are no objects, any selected objects are deselected.
Right-clicking activates a viewport without changing the selection state of objects. (You can also do this by left-clicking the viewport label.)
To switch between single and multiple viewports, do one of the following:
To change viewports when one is maximized:
This opens the viewport-switching interface.
Alternatively, simply click the desired viewport.
To resize the viewports:
If you don't drag a corner, you can move the borders horizontally or vertically only.
