How to split one large display into two or more
Users who have large displays may want to divide them into two different sections, either vertically or horizontally. For a user to gain this functionality, we suggest installing an appropriate third-party software program. The following sections contain some of these programs.
SplitView is a great program that allows you to display and manage split windows. The program does not necessarily create separate displays, but it does give the user a much easier way to split their windows and move them on the screen. Once installed, two additional buttons will be added to each window at the top left-hand corner that can be clicked to split the window.
Users with nVidia video cards installed (version 3.0 desktop manager and later) can use the nVidia Grids to break up their windows. To do this, right-click on the nVidia settings, open nVidia Desktop Manager, and click Edit Display Grids. Once you've edited the display grids, you can move windows by holding down Alt and dragging the window to a grid. Alternatively, users may right-click on the window bar, click nVidia Options, and select maximize to grid.
