Toshiba LTD121EXED panel EDID dump, with D420 noted in brackets in the name, possibly a laptop or variant reference, though the name does not explain it. The file is 128 bytes, one standard EDID base block. It holds the panel's identification, native mode and timing data that the video BIOS and driver read over DDC. Technicians write it back to the panel's serial EEPROM after corruption or when a replacement panel reports wrong data. Verify the panel model, and keep a copy of the original contents before programming.
