Port Configuration Field

Description

Readable Port Name

Enter a name for the port. This is a required field and the name must be between 1 and 50 characters and may contain spaces.

Port Rotation

This list allows you select a rotation for the display connected to this port. You can choose between 0, 90, 180, and 270 degrees. The default is 0.

Flip Port

Check this box if you want the display connected to this port to be inverted horizontally. The default is not to invert horizontally.

CenterOff

When this option is enabled it DISABLES centering. Also, depending on the combination of “edid” + “user-dtd” + connected hardware, Intel^® EMGD will add missing compatibility modes (6x4, 8x6, 10x7& 12x10) via centering. Use this option to disable this feature.

EDID Options

This section allows you to set EDID options for the display. The Intel^® EMGD supports three different types of EDID display modes:

• Built-in display modes: These modes are hard-coded in the Intel^® EMGD. These modes can be filtered based on the EDID block.

• EDID Block: These are Detailed Timing Descriptors read from an EDID display. An EDID display can contain DTD as well as other information about the display.

• User-specified DTDs.

If you want to use the display's EDID information if it is available, click the Use EDID Display if Available check box.

If the display attached to this port contains EDID information, you can choose one or more of the following options from the If EDID Device section to determine which set of timings to use for the display connected to the port:

• Use driver built in standard timings — If this box is checked, the standard timings built into the Intel^® EMGD are used.

• Use EDID block — If this box is checked, the EDID block is used.

• Use user-defined DTDs — If this box is checked, a user-defined DTD is used. You can select which DTD to use by checking the appropriate box in the Custom Display Timings Descriptors (DTDs) section. If no DTDs are defined, you can click New DTD and create a custom DTD. For information on creating custom DTD, refer to Table 18. Windows OS Setting Options.

If you select both Use driver built-in standard timings and Use EDID block, the Intel^® EMGD uses its built-in display timings and the timings provided by the display.

If the display attached to this port does not contain EDID information, you can choose one or both of the following options from the If Not EDID Device section:

• Use driver built-in standard timings — If this box is checked, the standard timings are used.

• Use user-defined DTDs — If this box is checked, a user defined DTD is used. You can select which DTD to use by checking the appropriate box in the Custom Display Timings Descriptors (DTDs) section. If no DTDs are defined, you can click New DTD and create a custom DTD. For information on creating custom DTD, refer to Table 18. Windows OS Setting Options.

See Sample Advanced EDID Configurations for example configurations.

DisplayID Options

This option provides flexibility to enable/disable display rotation configuration based on DisplayID file.

To enable display rotation configuration based on DisplayID file, please ensure you do following:

• Check the Determine rotation from device orientation option box

• Leave the Port Rotation and Flip Port options under CED LVDS or sDVO configuration page unchecked or set to 0.

• Check the Use EDID display if available option box and under “If EDID Device (edid_avail)” check the EDID block option for the graphics driver to get the rotation information from DisplayID file.

Note: If you set the Port Rotation and Flip Port option in CED to a non-zero value, then the graphics will use your setting regardless of the DisplayID option enabled.

Encoder Configuration

This section lets you to specify the type of encoder connected to an sDVO port and encoder Attributes, I2C settings, and Flat Panel settings for the port.

The Select sDVO Device drop-down list contains the list of all supported sDVO devices. Select the device that will be connected to this port.

To change the device's attributes, click the Attribute Settings button. Refer to Changing Port Attribute Settings for information on device attributes.

To change the device's I2C settings, click the I2C Settings button. See Changing I2C Settings for information on I2C settings.

To change the device's flat panel settings, click the Flat Panel Settings button. See Changing Flat Panel Settings for information for changing flat panel settings.

Framebuffer Color Correction Attributes

Framebuffer Color Correction Attributes allow you to adjust the main Frame Buffer color attributes. See Framebuffer Color Correction Attributes.

Native DTD Flag

The Native DTD list lets you choose whether to use a display's built-in timings.
