The positioning of the display is relative to the vertical and horizontal sync pulses. The display consists of the screen
colour covering the whole screen and the text area that is placed within the visible screen area. The screen colour
extends over a large vertical and horizontal range so that no offset is needed. The text area offset in both directions is
relative to the vertical and horizontal sync pulses.
