Since qualifying DisplayID descriptors are required to have all information necessary to replace the EDID, DisplayID descriptors may need to span multiple EDID 128-byte extension blocks. Manufacturers are recommended to pick panels with support for at least 384 bytes (3 blocks) of storage to accommodate descriptor changes.
