Chapter 4:
Installing a Secondary (Dual) Display
The Motherboard uses an integrated video controller; the Mobile Intel 4 Series
Express Chipset Family. This controller provides a Notebook port (Primary LCD) and
a Monitor port (VGA) on the Backplane connector row.
These two ports can provide either a single display mode (Notebook or Monitor) or a
dual display mode (Notebook and Monitor). Dual display mode can be a clone (same
video data displayed on both displays) or an extended desktop (the desktop spans
across both displays). The Notebook display (LCD) is the primary display in most
cases.
Configuring the Graphics Controller
This section talks about how to configure dual displays when using the Graphics Media
Accelerator Driver or using the Graphics Options controls directly from the Desktop. The
controller is included in the NCR Gold Image.
There are three ways to open the Intel® Graphics Media Accelerator Driver window:
•
Right click the Desktop. Then from the menu select:
Graphics Properties .
•
Click the Intel Graphics Accelerator Driver for Mobile icon in the Task Bar. Then from
the menu select:
Graphics Properties .
•
From within the Windows Control Panel, select the
Intel(R) GMA Driver icon.
Note:
The display selections in the Intel Control Panel vary, depending on what
displays are connected. The example above shows an integrated LCD primary
(Notebook) and an LCD secondary (Monitor) connected.
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 Microsoft 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.
