Abstract
A display mode selection method for selecting one display mode with respect to an input display signal from a table which defines a horizontal scanning frequency, a vertical scanning frequency and a resolution for a plurality of display modes, includes the steps of storing the plurality of display modes in the table in a plurality of blocks so that display modes having mutually overlapping tolerable ranges of the horizontal scanning frequency are included in the same block, obtaining a block number with respect to the input display signal by substituting a horizontal scanning frequency of the input display signal into a calculation formula which describes the block number of the blocks as a function of the horizontal scanning frequency, and selecting a display mode with respect to the input display signal from a display mode of the obtained block number by making a reference to the table.
