Second copy of a 256-byte EDID image for the LG LP156WH2 laptop panel, possibly taken from another unit or panel variant, so compare it with any other copy before choosing one. The binary is programmed into the display EEPROM over I2C to restore correct detection of resolution and timing. Check the exact panel model and sub-revision on the rear label, and back up the original EEPROM contents so you can revert if the picture or detection gets worse.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @laptop_bios_schematic. Enginerys does not host this file.
