In addition, BIOS setup provides the following configuration parameters for internal

flat panel displays:

•

Screen Brightness: allows the end user to set the screen brightness for the display

effective through the Power-On Self Test stage (such as while showing the splash

screen image and BIOS setup).

Windows 7 will ignore this setting in favor of the

native “screen brightness” control provided by the operating system.

•

Flat Panel Configuration Changes Lock: allows the system integrator to “lock”

critical settings of the LVDS configuration to avoid end users potentially rendering

the display unusable.

•

Brightness Steps: allows the system integrator to configure the brightness steps for

the operating system’s “screen brightness” control (such as the “Screen brightness”

adjustment slider under the Windows 7 “Power Options” control panel).

•

LVDS Interface Type: allows the system integrator to select whether the LVDS

panel is a single-channel or dual-channel display.

•

Swap LVDS Channels 0/1: allows the system integrator to swap the EVEN/ODD

LVDS channel assignments shall the cable be wired opposite the panel pinout.

•

Color Depth: allows the system integrator to select whether the panel is 24 bpp

with VESA color mapping (eDP and LVDS), 24 bpp with JEIDA color mapping (LVDS

only), or 18 bpp (eDP and LVDS).

•

eDP Interface Type: allows the system integrator to select whether the eDP panel is

a 1-lane, 2-lane, or 4-lane display.

•

eDP Data Rate: allows the system integrator to select whether the eDP panel runs

at 1.62 Gb/s or 2.7 Gb/s.

•

Inverter Frequency and Polarity: allows the system integrator to set the operating

frequency and polarity of the panel inverter board.

•

Maximum and Minimum Inverter Current Limit (%): allows the system integrator to

set maximum PWM%, as appropriate, according to the power requirements of the

internal flat panel display and the selected inverter board.

•

Panel Power Sequencing: allows the system integrator to adjust panel sequencing

parameters, if necessary.

•

LVDS Spread Spectrum Control: allows the system integrator to adjust spread

spectrum for the LVDS interface.

NOTE

Support for flat panel display configuration complies with the following:

1.

Internal flat panel display connectivity is disabled (and all parameters hidden) by

default.

2.

Internal flat panel display settings are not exposed through Intel

®

Integrator

Toolkit or Intel

®

Integrator Assistant GUIs.

3.

Internal flat panel display settings will not be overwritten by loading BIOS setup

defaults.

4.

Internal flat panel display settings will be preserved across BIOS updates.
