LG LP173WD1 display EDID, TL type, revision A3, delivered as a 256-byte binary. The data lets the system identify the panel and set native timings via the DDC channel. Rewriting it is a common fix when the EEPROM was wiped or corrupted and the laptop refuses to light the internal screen properly. Since this model has several revision files, pick the one whose suffix matches the sticker on the back of the panel, and always back up the current EEPROM contents before programming.
