Adjusting the Screen ImageManually Correcting Keystone Distortion
The projector is provided with an automatic keystone correction function 
which detects the vertical angle of the projector and carries out keystone 
correction automatically. If further correction adjustment is required after 
automatic keystone correction has been carried out, use the [Keystone] 
buttons on the projectors control panel to make the adjustment.PROCEDURE
Projector Projector
If the bottom of the 
image is elongated
If the top of the 
image is elongated
TIP
 When keystone correction is carried out, the projected image will  become smaller.
 If the images become uneven in appearance after keystone  correction is carried out, decrease the sharpness setting. 
 p.51 , p.54
 Keystone correction can also be carried out using the configuration  menu.   p.58
 If the value displayed in the gauge on the screen stops changing  when keystone correction is being carried out, it indicates that the 
limit for keystone correction has been reached. Check that the 
projector has not been set up at an angle which exceeds the proper 
limit.

Adjusting the Image QualityThe quality of the screen images can be adjusted as follows.Adjusting 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
, Position and  Sync. (Synchronization)
.
Automatic Setup
TIP
 If Auto Setup in the Image menu is set to OFF (the default 
setting for this item is ON), automatic setup is not carried out. If 
you press the [Auto] button on the remote control while computer or 
RGB video signals are being projected, adjustment will then be 
carried out. If you press the [Auto] button while the E-Zoom or Freeze function is  being used or while a configuration menu or help menu is being 
displayed, the function will be cancelled when you press the [Auto] 
button, and then the adjustment will be carried out. Sometimes the signals may not be adjusted correctly depending on the type of computer or RGB video signals being output. In such 
cases, use the configuration menu commands to adjust the tracking 
and sync settings manually.    p.42, p.43

Adjusting the Image QualityIf 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
 manually using the 
following procedure.
PROCEDURE
Press the [Menu] button on the remote control, and then 
select Tracking from the Image menu.For details on this operation, refer to Using the Configuration 
Menus.   p.66
Press the [ ] and [ ] buttons to set the tracking value 
to a value that causes the vertical stripes to 
disappear from the image.
The tracking value increases or decreases each time a button is 
pressed.After making the adjustment, press the [Menu] button 
to exit the configuration menu.

TIP
The image will flash when continuous tracking adjustment is carried 
out, but this is normal.

Adjusting the Image QualityIf 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. (synchronization)
 manually 
using the following procedure.
PROCEDURE
Press the [Menu] button on the remote control, and 
then select Sync. from the Image menu.
For details on this operation, refer to Using the Configuration 
Menus.   p.66
Press the [ ] and [ ] buttons to set the sync value to 
a value that causes the flickering, fuzziness or 
interference to disappear from the image.
The sync value increases or decreases each time a button is 
pressed.After making the adjustment, press the [Menu] button 
to exit the configuration menu.
Adjusting the Sync1
23
TIP
 If you adjust the sync without adjusting the tracking 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.
 It may also be possible to fix flickering and fuzziness by adjusting the  brightness,  contrast
 , sharpness and keystone correction settings.

Adjusting the Image QualitySelecting the Projection Quality (Colour Mode Selection)
The following six preset colour modes are available for use depending on 
the characteristics of the images that are being projected. You can easily 
obtain the optimum image quality simply by selecting the colour mode that 
corresponds to the projected images. The brightness of the images will 
vary depending on which colour mode is selected.The default setting for the colour mode is as follows.
