Edid shadowing techniques for fast display startup

An electronic display comprising:

• a memory device configured to store extended display identification data (EDID);
• a timing controller configured to:
• access EDID from the memory device;
• store EDID from the memory device;
• after storing EDID from the memory device, transmit a signal to a host device to indicate that the host device can access the stored EDID;
• access configuration data from the memory device;
• and
• after transmitting the signal to the host device, transfer the stored EDID to the host device while accessing the configuration data from the memory device.

A method for starting an electronic display of an electronic device comprising:

• receiving a startup signal at the electronic display indicating to the electronic display to begin accessing extended display identification data (EDID);
• accessing, by the electronic display, EDID from a non-volatile memory device of the electronic display;
• storing EDID from the memory device in a volatile memory device of the electronic display;
• after storing EDID from the non-volatile memory device, transmitting a signal from the electronic display to a processor to indicate that the processor can access the stored EDID;
• accessing, by the electronic display, configuration data from the non-volatile memory device;
• and
• after transmitting the signal to the processor, transferring the EDID stored in volatile memory device of the electronic display to the processor while the electronic device is accessing the configuration data.
