H-position:
Adjust the position of the display horizontally (left or right).
V-position:
Adjust the position of the display vertically (up or down).
Clock:
Using the “clock” signal, the image can be adjusted in a way that
vertical bars/stripes are reduced or minimized. This is achieved by
aligning the clock pulse with the received pixels.
Phase:
Reducing or minimizing the horizontal bars/stripes and noise.
Hence the image sharpness can be adjusted. This is achieved by
aligning the phase length with the received pixels.
