HannStar HSD121PWH1

BIOS .bin 256 B Shared

HannStar HSD121PWH1 panel EDID data in a 256-byte binary. This 12.1-inch class display stores its identification block in a small serial EEPROM, and the file reproduces that block so it can be restored after corruption. Typical symptoms that call for it are a black screen with working backlight, an unknown monitor in the OS or an incorrect native resolution. Use an I2C EEPROM programmer, confirm the part number printed on the panel, and keep a copy of the original dump before overwriting.
