Provides a list of optional adjustments which include the following:
MOIRE CANCELLER: Moiré can be visible if large areas of dithered
colour are displayed (overall colour made from alternating pixels of
different colours). The Moiré Canceller allows you to minimize this
phenomenon, using the +/- CONTROL buttons.
LINEARITY: The Linearity selection allows you to adjust the spacing
of the areas on the screen. The purpose of this control is to ensure that a
2 cm circle is a true 2 cm circle wherever it is drawn on the screen. The
best way to determine the vertical linearity is as follows:
–
Draw equally spaced horizontal lines using a drawing
application that has a ruler.
–
Use the Vertical control to adjust the spacing between the lines
near the centre of your screen.
–
Use the Vertical Balance control to adjust the lines near the top
and bottom of your screen.
CONVERGENCE: To adjust the convergence of the three beams to
display real white lines without color shadows select horizontal or
vertical . Adjust the control bar using +/- buttons to eliminate color
shadows and make the line completely white.
GLOBALSYNC: Eliminates color impurity that may result from the
Earth's magnetic field. Move the location of the control bar to the
closest compass point that corresponds with the direction in which the
CRT faces. Adjust the control until the most even level of blue is
reached. Exit to the sub-menu after completion.
