To arrange displays in a multiple display environment
1.Right-Click Desktop. Properties
2 Click the Advanced button.
3 Click on the Displays tab.
Your display device must be enabled before you can change its display mode.
4 Click the display mode buttons according to the desired arrangement for your displays.
A button state change indicates when the Primary or Clone mode is selected for a particular display, but no action is taken until you apply your changes. Each display has two options:
Click the Primary button
to set the associated display as primary. In an extended desktop environment, this will be associated with display icon 1 on the Settings tab.
Click the Clone button
to set the associated display to show a copy of the primary display desktop image, OR, in an extended desktop environment, to show the portion of the desktop that is extended (see Note below). Clicking the Clone button on the primary display will automatically switch the primary assignment to another available display, thus toggling the display assignments.
5 Click either OK or Apply to save the changes you have made.
Notes
At least one of your displays must be enabled.
At least one of your displays must be set as the primary display.
To switch from an extended desktop to clone mode, you must first disable the extended desktop via the Settings tab. Then you can repeat the above procedure to enable clone mode.
Video Overlay allows for the viewing of full-motion video on your computer. However, there is only one video overlay in hardware. For display arrangements consisting of a primary and a clone, the video overlay is only available on the primary display. (For extended desktop arrangements, the video overlay will be visible across all displays.)
For systems with flat panel and TV support, you cannot set both the flat panel display and TV to the same display mode.
