Alternate EDID dump for the Chi Mei N156BGE-L21 laptop panel, labelled (2) and without a stated revision. At 256 bytes it contains the panel descriptor read by the graphics controller to select resolution and timings. It can be compared with the other L21 dumps to choose the closest match to your panel. Common repair use is restoring a wiped or corrupted EDID that leaves the screen black or misdetected. Decode it to verify the checksum and fields, check the panel label, and save the original data before writing.
