Adjusting the Image QualityAdjusting Computer Images and RGB Video Images
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:
Tracking
g, 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 projectors control panel to make the adjustment 
while computer or RGB video images are being projected.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 Tracking
g manually using the 
following procedure.
PROCEDUREA
Select Signal from the configuration menu, and 
then select Tracking.
For details on this operation, refer to 
Using the Configuration 
Menu
. sp.32
Check the buttons you can use and the operations they perform 
in the guide at the bottom of the screen.
Automatic Setup
• If you press the [Auto] button on the remote control, or 
the [Enter] button on the control panel, while 
performing other functions such as E-zoom or Freeze, 
these functions are canceled and then the adjustment is 
made.
 Sometimes the signals may not be adjusted correctly 
depending on the type of computer or RGB video 
signals being input. In such cases, use the 
configuration menu commands to adjust the tracking 
and sync settings manually. sp.13Using the remote control

pressed.
C
Press the [Menu] button to exit the configuration 
menu.
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.
PROCEDUREA
Select Signal from the configuration menu, and 
then select Sync..
For details on this operation, refer to Using the Configuration 
Menu
. sp.32
Check the buttons you can use and the operations they perform

Adjusting the Image QualityB
Adjust the synchronization until the horizontal noise 
disappears from the image.
The sync value increases or decreases each time a button is 
pressed.
C
Press the [Menu] button to exit the configuration 
menu.
 If you adjust the sync without adjusting the tracking
g 
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 check 
the tracking adjustment first.
 Flickering and fuzziness may also occur when the 
brightness, contrast
g, sharpness, zoom, and keystone 
correction settings are adjusted.
