If flickering, fuzziness or interference appear
in images that are input from the computer,
and this cannot be fixed using automatic
adjustment, you will need to adjust the
synchronization manually using the following
projection.
Procedure
While holding down the [Shift] button
on the projector's control panel, press
the [Sync +] button.
The synchronization value will increase by
one setting each time the [Sync +] button is
pressed.
While holding down the [Shift] button
on the projector's control panel, press
the [Sync -] button.
The synchronization value will decrease by
one setting each time the [Sync -] button is
pressed.
Tip :
• If you do not adjust the tracking first and then adjust the synchronization, it will not be
possible to get the best adjustment results. Incorrect tracking adjustment may not be
noticeable with some types of picture. However, pictures with lots of lines and shading
will tend to show incorrect tracking adjustments more clearly, so be sure to check the
tracking adjustment first.
• It may also be possible to fix flickering and fuzziness by adjusting the brightness,
contrast , sharpness and keystone correction settings.
