Multi-monitor is supported on most Intel® 830M/830MG chipset-based systems through the use of an additional graphics controller designed into the chipset. Several different multi-monitor options are supported by the Intel 830M/830MG chipset. The availability of each of these options is dependent upon the specific motherboard implementation.

Multi-monitor modes are as follows:

• Intel® Dual Display Clone
  
  
  • Intel Dual Display Clone is used to drive multiple displays with the same content. Each display device can be configured independently, allowing each to have a different refresh rate, color depth, and resolution for optimum display on each device.
  • Intel Dual Display Clone is beneficial when using displays of various types and sizes, such as one pipe driving an integrated LCD (Liquid Crystal Display) while the other drives an analog overhead projector that may only support specific resolutions and refresh rates.
  • To activate Dual Display Clone, click the the 'Intel(R) Dual Display Clone' icon on the Devices tab of the 'Intel(R) 82830M Graphics Controller Properties' window. Choose the Primary Device and the Secondary Device and click Apply.
    
    
    
    
• Extended Desktop
  
  
  • One important use for multi-monitor is to allow for a large Windows* desktop that spans multiple displays, creating more screen real estate than a single display provides.
  • The Display applet in Control Panel or the Devices tab in the 'Intel(R) 82830M Graphics Controller Properties' window can be used to configure the size and relative position of each monitor.
  • Applications can be moved from one monitor to another, or can be on more than one monitor simultaneously.
  • To activate Extended Desktop, click on the 'Extended Desktop' icon on the Devices tab of the 'Intel(R) 82830M Graphics Controller Properties' window. Choose which device will be the Primary Device and which one will be the Secondary Device and click Apply.
    
    
    
    
  • The Display item on the Settings tab in Control Panel can also be used to enable this mode. Note that the 'Intel(R) 82830M Graphics Controller Properties' window must be used to enable Extended Desktop if Intel Dual Display Clone is currently enabled.
    
    
    
    
  • Applications may behave differently in a multi-monitor configuration depending on their implementation:
    • Standard Windows applications that use the GDI (Graphics Device Interface) will clip the window to each display and accelerate the images separately using the display hardware.
    • Applications that span multiple monitors and use DirectX*, Direct3D*, or DirectDraw*, will be software accelerated.
    • OpenGL* applications may exit unexpectedly, hardware accelerate one display with unknown results on the other, or be software accelerated.
    • A full screen command prompt or MS-DOS* application will only function on the Primary Device.
      
• Dual-Pipe Panning
  
  
  • Dual-Pipe Panning allows a high-resolution display on a larger screen, while viewing a zoomed-in version on a smaller screen.
  • The view on the smaller screen is tied to mouse cursor movement. Since the screens are different sizes, the mouse cursor may be at different positions on either screen.
  • While it is within the zoomed-in area of the smaller screen, the cursor acts as normal. As the cursor moves near the edge of the smaller screen, the view pans toward the cursor until the edge of the full screen is reached. This does not affect the view on the larger screen, which stays the same regardless of the activity of the smaller (panned) screen.
  • Dual-Pipe Panning is used in conjunction with Intel Dual Display Clone or Multi. To use Dual-Pipe Panning, first enable Intel Dual Display Clone or Multi, then set the cloned display devices to a larger resolution than one of the cloned displays supports and click Apply. The device that cannot support the full resolution will be panned.
    

Intel® Dual Display Multi

• Note: Intel Dual Display Multi is not supported in the 14.x driver baseline. The last driver that support this feature was version PV 13.6 (3722). If you wish to use Intel Dual Display Multi, please use driver 13.6 or older. 
• Intel Dual Display Multi features two displays driven by one pipe in Intel Dual Display Twin mode, and a third independent display driven by a separate pipe.
• Intel Dual Display Multi is especially useful in environments where the user is displaying content to an audience using multiple displays, but at the same time performing work on their own display independently. An example would be if a system were showing a demo on two displays while the user also took notes on the third display.
• To activate Dual Display Multi, first enable Extended Desktop, then click the 'Enable Twin Configuration' checkbox and click Apply. You will need three display devices attached, such as an internal laptop display, a CRT monitor, and a television.
  
  
  
  
• System Requirements for Multi-monitor:
  
  
  • System based on integrated Intel 830M/830MG chipset that has dual pipe enabled by the system manufacturer.
  • Two or more display devices (e.g. CRT, Flat Panel, TV, etc.).
  • Windows* 98, Windows 98 Second Edition (SE), Windows Millennium Edition (Me), Windows 2000, or Windows XP
  • Current graphics driver for the Intel 830M/830MG chipset.
