LG Display LP156WH4 EDID dump for the TL A1 variant, a 15.6-inch HD notebook panel. The 256-byte file is the identification and timing data stored in the small EEPROM on the panel and read through DDC by the graphics chip. Technicians use it to recover a panel that is undetected or shows incorrect resolution after its EDID was corrupted. The TL and A1 codes on the panel label should match exactly; back up the existing chip contents and verify the write with a read-back using an I2C EEPROM programmer.
