128-byte EDID block named dell121xj, apparently for a 12.1-inch XGA panel in a Dell laptop, though the panel maker and part number are not given. A 128-byte base EDID tells the video controller supported resolution and timings. Rewriting it into the LCD EEPROM restores proper panel detection after corruption. Open it in an EDID tool to read the embedded panel ID and confirm it matches your screen. Save the current EEPROM contents before writing, since a mismatch may leave the display blank.
