The twelve kinds of timings below are already programmed in this module. The input synchronous
Expansion mode is a function to expand the screen size in different resolutions. For example, VGA
signal has 640 480 pixels. But, if the display data can be expanded to 2.0 times vertically and
horizontally, VGA screen image can be displayed fully on the screen of SXGA resolution. This
module automatically recognizes the timing shown in item 3.7 PRESET TIMINGS as an expansion
mode.
Adopt this mode after evaluating display quality, because the appearance in the expansion mode is
happened to become bad in some cases.
