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.
