[Remarks]
*1 When 50Hz data is set, the setting data is increased or decreased to set 60Hz data.
(However, 50Hz data does not vary when 60Hz data is set.)
*2 Because of the fixed data, it is unnecessary to set the data unless otherwise specified.
*3 It is impossible to set (use) the data "6" and "7". Use "0" thru "5".
Moreover, check whether "6" and "7" are used or not.
*4 When the data for the 1-screen mode is set, the set data is increased or decreased to set
the data for the 2-screen mode.
