No
Yes
If set to ‘Yes’ the BIOS will first look for an EDID data set in an external EEPROM to configure the
Local Flat Panel. Only if no external EDID data set can be found, the data set selected under ‘Local
Flat Panel Type’ will be used as a fallback data set.

Select a predefined LFP type or choose Auto to let the BIOS automatically detect and configure the
attached LVDS panel.
Auto detection is performed by reading an EDID data set via the video I²C bus.
The number in brackets specifies the congatec internal number of the respective panel data set.
Note: Customized EDID™ utilizes an OEM defined EDID™ data set stored in the BIOS flash device.
