The Intel®
Embedded Media and Graphics Driver is composed of a runtime graphics driver and a
Video BIOS (VBIOS) firmware component. (See the illustrations below.)
Both the driver and VBIOS control the SCH to perform display and render
operations. The VBIOS is predominantly leveraged by System BIOS during
system boot but is also used at runtime by the driver to handle full-screen
text mode on Microsoft Windows* operating systems.

Display Options
The following section describes the types of displays
and configurations supported by the Intel®
Embedded Media and Graphics Driver.
Types of Displays
The table below lists the types of displays supported
by the Intel® Embedded
Media and Graphics Driver.
Table 2. Types of Displays Supported
Display
Description
CRT
Analog CRT, supported with an external transmitter
via an sDVO port.
Flat Panel
TMDS and LVDS compliant flat panels are supported
with the use of an external transmitter via an sDVO port. Integrated
LVDS flat panels are also natively supported on the Intel® System Controller Hub US15W/US15WP/WPT
chipset and Intel® Atom™
Processor E6xx.
TV
TV-out is supported via an external encoder sDVO
port.
Note:TV-Out is enabled via supported internal capability, or
external transmitters sDVO (where available).
Display Configuration
Intel®
EMGD supports driving two displays simultaneously. Several
configurations are supported, dependent on operating system and chipset.
The various display configurations are described in the table below.
Table 3.Display Configuration Definitions
Display Configuration Mode
Description
Single
Normal desktop configuration, single monitor
Clone*
Two displays, same content, different resolutions,
independent timings
Extended*
Two displays, continuous content (available in Windows
only)
DIH*
Dual Independent Head. Two displays, different content,
independent resolutions
* Supported display depends on driver and hardware
availability. See the RelNotes.txt for more information.
The table below summarizes which display configurations
are supported by Intel chipsets.
