Maybe these last lines could be

   0x00, 0x00, 0x00, 0x00, 0x00, 0xFC, 0x00,  'Q',
   'X',  'L',  '0',  '0',  '0',  '1',  '\n',  ' ',
   ' ',  ' ',  ' ',  ' ',  0x00, 0x00, 0x00, 0xFC,
   0x00, 'Q',  'X',  'L',  '0',  '0',  '0',  '1',
   '\n', ' ',  ' ',  ' ',  ' ',  ' ',  0x01, 0x6E,

Why 2 "Monitor name"  (0xFC) descriptions?
