Intel Desktop Board D525MW and Intel Desktop Board D525MWV Technical Product Specification 1.5.1.4 Configuration Modes For monitors attached to the VGA port, video modes supported by this board are based on the Extended Display Identification Data (EDID) protocol. Video mode configuration for LVDS displays (D525MWV only) is supported as follows: Automatic panel identification via Extended Display Identification Data (EDID) for LVDS panels supporting EDID protocol. • Manual LVDS panel configuration through the BIOS setup page. This feature allows the manual entry of critical panel settings (equivalent to the 18-byte Detailed Timings Descriptor structure defined by the VESA EDID specification) for non-EDID panel support. In addition, BIOS setup provides the following configuration parameters for LVDS displays (D525MWV only): • Screen Brightness: allows the end-user to set screen brightness for the display. • Maintain Aspect Ratio: allows the end-user to select whether the native aspect ratio is to be preserved during POST and before the video driver is loaded. • LVDS Configuration Changes: allows the system integrator to "lock" critical settings of the LVDS configuration to avoid end-users potentially rendering the display unusable (refer to Note 1). • Inverter Frequency and Polarity: allows the system integrator to set the operating frequency and polarity of the panel inverter board. • Minimum Inverter Current Limit (%): allows the system integrator to set minimum PWM%, as appropriate, according to the power requirements of the LVDS display and the selected inverter board. • NOTE Support for LVDS (D525MWV only) configuration complies with the following: 1. "Unlocking" of critical settings of the LVDS configuration is supported via Intel® Integrator Toolkit's command-line tool. 2. Critical settings of the LVDS configuration are not exposed through Intel Integrator Toolkit or Intel® Integrator Assistant GUIs. 3. Critical settings of the LVDS configuration will not be overwritten by loading BIOS setup defaults. 4. Critical settings of the LVDS configuration will be preserved across BIOS updates. 18

Intel Desktop Board D525MW and Intel Desktop Board D525MWV Technical Product
Specification

1.5.1.4
Configuration Modes
For monitors attached to the VGA port, video modes supported by this board are
based on the Extended Display Identification Data (EDID) protocol.
Video mode configuration for LVDS displays (D525MWV only) is supported as follows:
•
Automatic panel identification via Extended Display Identification Data (EDID) for
LVDS panels supporting EDID protocol.
•
Manual LVDS panel configuration through the BIOS setup page.
This feature
allows the manual entry of critical panel settings (equivalent to the 18-byte
Detailed Timings Descriptor structure defined by the VESA EDID specification) for
non-EDID panel support.
In addition, BIOS setup provides the following configuration parameters for LVDS
displays (D525MWV only):
•
Screen Brightness: allows the end-user to set screen brightness for the display.
•
Maintain Aspect Ratio: allows the end-user to select whether the native aspect
ratio is to be preserved during POST and before the video driver is loaded.
•
LVDS Configuration Changes: allows the system integrator to “lock” critical settings
of the LVDS configuration to avoid end-users potentially rendering the display
unusable (refer to Note 1).
•
Inverter Frequency and Polarity: allows the system integrator to set the operating
frequency and polarity of the panel inverter board.
•
Minimum Inverter Current Limit (%): allows the system integrator to set minimum
PWM%, as appropriate, according to the power requirements of the LVDS display
and the selected inverter board.
NOTE
Support for LVDS (D525MWV only) configuration complies with the following:
1.
“Unlocking” of critical settings of the LVDS configuration is supported via Intel
®
Integrator Toolkit’s command-line tool.
2.
Critical settings of the LVDS configuration are not exposed through Intel Integrator
Toolkit or Intel
®
Integrator Assistant GUIs.
3.
Critical settings of the LVDS configuration will not be overwritten by loading BIOS
setup defaults.
4.
Critical settings of the LVDS configuration will be preserved across BIOS updates.
