Clock - Adjustment |
As most LCD's use standard VGA interfaces to fit on each graphic board,
the analogue signal of the graphic board from the display has to be converted
into a digital one. According to the resolution used, the signal has to
be sampled. The picture width and picture position are defined by
the CLOCK and CLOCK-PHASE.
For an optimal adjustment of these parameters, a test pattern with vertical
stripes is suitable.
