Convergence
Horizontal & Vertical Convergence adjustment
Hor. Convergence: adjusts Horizontal Convergence
Ve r. Convergence:
Convergence is the monitor's ability to precisely illuminate specific phosphors
and line them up properly in order to produce pure color. Displayed characters and
images may appear fuzzy or have tinges of red , green, or blue if the electron beams do
not converge correctly.
adjusts Vertical Convergence
Acer 211c offers a convergence adjustment feature. To properly adjust
convergence, it is best to have an image that makes it easy to see any
convergence error. A black background with white letters or lines is
recommended. When adjusting convergence, look at the adjustment across
the whole screen. When adjusting horizontal convergence, look at the left
and right edges of vertical lines or characters. When adjusting vertical
convergence, look at the top and bottom edges of horizontal lines or
characters. The monitor is properly adjusted when the effects of red and
blue tinges are minimized.
?
The convergence adjustment adjusts the entire screen. It is not
possible to limit adjustment to specific screen areas.

Moire
Horizontal & Ver tical Moire adjustment
Horizontal Moire: adjusts horizontal Moire
Vertical Moire: adjusts vertical Moire
Moire refers to an interference pattern of dark wavy lines on the screen. It is an
interference phenomenon caused by the relationship between the phosphor layout
and the imaging signal. In fact, it is often considered an indication of good focus level.
?
It is especially noticeable when using a light-gray or every-other-
dot pattern. Moire cannot be eliminated. Howeve r, it can be reduced with the moire reduction featu re.
Moire can be reduced by adjusting the iscreen moire reduction function. Prior to
adjustment, set the screen to a full white pattern so that moire will be visible. After this
adjustment, make changes to a different screen background in order to reduce moire
even further.
?
If the picture is unstable when you adjust the moir e reduction
setting, over-adjustment has occured. Please lower the moire re-
duction setting level. (Factory default setting value : 0).
