Convergence

Horizontal & Ver tical Convergence adjustment

Hor. Convergence: adjusts Horizontal Convergence
Ver. Convergence:

adjusts Vertical 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.

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. Howe ve r, it ca n be re­duced with the moire reduction feature.

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 w hen you adjust t he moire r eduction
setting, over-adjustment has occured. Please lower the moire re-

duction setting level. (Factory default setting value : 0).

refresh rate according to your preferences. The monitor will automatically save the
settings. Your monitor can accept a vertical frequency ranging from 50 Hz to 160 Hz
and an horizontal frequency from 30 KHz to 107 KHz. However, due to different
video card and resolution settings, we recommend that you do not exceed the maxi­mum refresh rate, 160 Hz for vertical frequency and 107KHz for horizontal frequency
to avoid possible damage to your monitor.
