Appendix C:  Detailed Setup Information
C-1. Setting Representation, Resolution
Most computers do not just support one single screen mode but rather a series of different modes which
differ in type of representation (text or full graphic), resolution (number of pixels) and number of colors.
Pre-stored standard mode settings for a variety of IBM compatible and Apple Macintosh computers help
the projector to recognize the current mode and adjust for optimum performance automatically.
Apart from this you can enter and save additional modes with any parameters by means of the menu
system. An upper limit is given by the maximum admissible pixel rate (Appendix A-1).
Adjust the projector to optimum display quality, as described below, by using the menu control (see
section 4-4). All steps described can be carried out via the keyboard or the remote control:
1.
 Adjust the background as necessary to obtain a display with the highest possible contrast. For use
under Microsoft Windows it is recommended that you close all applications first, and by using the
system control, adjust the desktop background to an even black-and-white raster.
2.
 Call up the main menu of the projector by pressing the 
MENU key.
3.
 Select the 
Setup menu.
4.
 Open the 
Setup menu by pressing the 
ENTER key.
The current mode is displayed in the title block of the 
Setup menu. Change the mode field if
desired. Confirm your selection by pressing the 
ENTER key
5.
 Move to the menu item 
Pixel and select the same image resolution as your computer.
6.
 Select the menu item 
Brightness and correct the setting so that white areas are projected with
maximum intensity. Press the 
ENTER key for automatic adjustment.
Look at a finely structured area with grid lines. This area may have vertical interference lines
superimposed on it.
 
7.
 Select the menu item 
Tracking (image width) and adjust for minimum interference. The direction
of adjustment is correct when the number of lines decreases. The setting is optimal when no more
interference lines can be seen. An automatic setting of tracking and synchronization can be called
up by operating the 
ENTER key.  This works fine if an image with high contrast content is
displayed. 
						

							24 3MÔ Multimedia Projector MP8610Ó 3M 1998
8.
 Synchronize the phase position of the pixel frequency and scanning frequency. Choose the menu
item 
Sync. Image interference’s and flickers can be observed with some settings as shown in the
following figure:
 
 
 
9.
 In a range of several settings an image is projected that is free of interference. If the sync-setting
is correct, the image will improve as shown in following figure:
  
10.
 An automatic setting of the synchronization can be called up by using the 
ENTER key.
11.
 Minor interference, where one color meets another, can be corrected by manually adjusting the
Brightness and 
Contrast. Normally, the contrast should be set to approximately the medium
value. Lower values cause an increase in background intensity.
12.
 Center the projected image using the 
H. off and 
V. off settings.
13.
 To leave the Setup menu, press the 
MENU key.
14.
 If parameter settings have been changed, a warning is displayed. Confirm the changed settings
by using the 
ENTER key.
