LG LP154WX4 panel EDID image for the TL B4 revision, 15.4-inch WXGA. Unlike the B2 copy, this one is 128 bytes, a single base EDID block without extension. The data is read by the laptop over DDC to determine the panel resolution and timings, and restoring it into the EEPROM fixes a blank or misidentified screen. Check that B4 is printed on the panel label, read and save the current EEPROM before writing, and verify the result with a read-back on the programmer.
