Adjusting the Image Quality

Adjusting Computer Images and RGB Video Images

Automatic Setup

Automatic setup detects analogue RGB signals coming from a connected computer, and automatically adjusts these signals so that the optimum images can be obtained. Automatic setup involves adjustment of the following three items:

Trackingg, Position and Sync (synchronisation)g.

If "Auto Setup" in the "Signal" menu is set to "Off", automatic setup is not carried out. In this case, press the [Auto] button on the remote control or the [Enter] button on the projector's control panel to make the adjustment while computer or RGB video images are being projected.

Using the remote control

Using the control panel

Adjusting the Tracking

If vertical stripes appear in the projected computer or RGB video images, and this cannot be fixed using automatic setup, you will need to adjust the Trackingg manually using the following procedure.

PROCEDURE

Select "Signal" from the configuration menu, and then select "Tracking".

For details on this operation, refer to Menu
