Sample Advanced EDID Configurations

Configurations

CED Settings

Description

1. Use only filtered built-in and any EDID-DTDs when the display has EDID information

2. Use all built-in modes when the display does not contain EDID information

edid = 1

edid_avail = 3

edid_not_avail = 1

Default values.

1. Use only filtered built-in modes and EDID-DTDs when the display has EDID.

2. Use only user-DTDs otherwise.

edid = 1

edid_avail = 3

edid_not_avail = 4

This configuration allows the Intel® EMGD to use its built-in display modes and the modes provided by the display.

If the Intel® EMGD is unable to read EDID information from the display, then the Intel® EMGD uses the user-DTDs defined in CED.

1. Use only user-DTDs regardless of connected display. (Typically used for a custom panel that only supports user-defined DTDs.)

2. Use limited set of timings when a panel EDID is present, but the Intel® EMGD cannot read the EDID information.

edid = 0

edid_avail = (any value)

edid_not_avail = 4

Only user-DTDs defined in CED are used.

1. Use EDID-DTDs for an EDID display.

2. Use user-DTDs for a non-EDID display.

edid = 1

edid_avail = 2

edid_not_avail = 4

This configuration uses the EDID-DTDs when detecting an EDID display and EDID information comes from the display.

If the driver detects a non-EDID display, then the Intel® EMGD uses user-DTDs defined in CED.

1. Use only EDID-DTDs and user-DTDs for an EDID display.

2. Use user-DTDs only for a non-EDID display.

edid = 1

edid_avail = 6

edid_not_avail = 4

This configuration uses both EDID-DTDs and user-DTDs when the Intel® EMGD detects an EDID display.

If the driver detects a non-EDID display, then the Intel® EMGD uses user-DTDs defined in CED.
