Adjusting the Sync

If flickering, fuzziness or interference appear in computer or RGB video images, and this cannot be fixed using automatic setup, you will need to adjust the Sync (synchronisation)g manually using the following procedure.

PROCEDURE

1	Press the [Menu] button on the remote control or the
	projector's control panel, and then select "Sync." from

the "Signal" configuration menu.

For details on this operation, refer to "Using the Configuration Menus". sp.66

2	Tilt the [	] button on the remote control or press the
	[ ] and [	] buttons on the projector's control panel

to adjust the synchronisation value until the flickering, fuzziness or interference disappears from the images.

The sync value increases or decreases each time a button is pressed.

3	After making the adjustment, press the [Menu] button
	to exit the configuration menu.

TIP

•If you adjust the sync without adjusting the trackingg first, 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.

•Flickering and fuzziness may also occur when the brightness, contrastg, sharpness and keystone correction settings are adjusted.
