Tools 1
Moiré Canceler: Moiré is a wavy pattern which can sometimes appear
on the screen. The pattern is repetitive and superimposed as rippled
images. When running certain applications, the wavy pattern is more
evident than in others. To reduce moiré, adjust the level by using
-/+ control buttons.
Basic Convergence: Aligns all three colours (R,G,B) to form a single
colour (white). The purpose of this control is to ensure that a white line
drawn on the screen is as crisp and clear as possible.
• Use the Horizontal control to adjust the alignment of the white lines in
the up/down direction.
• Use the Vertical control to adjust the alignment of the white lines in
the left/ right direction.
Corner Correction:Allows you to adjust the geometry of the corners of
your display – Top, Top Balance, Bottom or Bottom Balance.
Linearity: This selection allows you to adjust the spacing of the area on
the screen. The purpose of this control is to ensure that a one-inch circle
is a true one-inch circle wherever it is 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 Balance control to adjust the lines near the top and
bottom of your screen.
• Use the Vertical control to adjust the spacing between the lines near
the center and top of your screen.
