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. However, it can be re-
duced 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 when you adjust the moire reduction
setting, over-adjustment has occured. Please lower the moire re-
duction setting level. (Factory default setting value : 0).
