Selecting the aspect ratio
The aspect ratio is the ratio of the image  width to the image height. Most analog TV and 
computers are in 4:3 ratio,  and digital TV and DVDs are usually in 16:9 ratio.
With the advent of digital signal processing,  digital display devices like this projector can 
dynamically stretch and scale the image output to  a different aspect than that of the image 
input signal. 
To change the projected image ratio (n o matter what aspect the source is):
1. Press  MENU/EXIT  on the projector or  Menu on the remote control and then press 
/  until the  DISPLAY menu is highlighted.
2. Press
  to highlight  Aspect Ratio .

About the aspect ratio
In the pictures below, the black portions are inactive areas and the white portions are active 
areas. OSD menus can be displayed on those unused black areas.
1. Auto: Scales an image proportionally to fit the 
projectors native reso lution in its horizontal 
width. This is suitable for the incoming image 
which is neither in 4:3 nor 16:9 and you want to 
make most use of the screen without altering the 
images aspect ratio.
2. 4:3: Scales an image so that it is displayed in the 
center of the screen with a 4:3 aspect ratio. This 
is most suitable for 4:3 images like computer 
monitors, standard definition TV and 4:3 aspect 
DVD movies, as it displays  them without aspect 
alteration.
3. 16:9: Scales an image so that it is displayed in 
the center of the screen with a 16:9 aspect ratio. 
This is most suitable for images which are 
already in a 16:9 aspect, like high definition TV, 
as it displays them wi thout aspect alteration.
4. 16:10 (PJD7583w/PJD7583wi only) : Scales an 
image so that it is disp layed in the center of the 
screen with a 16:10 aspect  ratio. This is most 
suitable for images which are already in a 16:10 
aspect as it displays them without aspect 
alteration.

Color Management
Only in permanent installations with controlled  lighting levels such as boardrooms, lecture 
theaters, or home theaters, should color management be considered. Color management 
provides fine color control adjustment to allo w for more accurate color reproduction, should 
you require it.
If you have purchased a test disc which contains  various color test patterns and can be used 
to test the color presentation on monitors, TV s, projectors, etc., you can project any image 
from the disc on the screen and enter the  Color Management menu to make adjustments.
To adjust the settings:
1. Go to the  DISPLAY menu and highlight  Color Management .
2. Press  MODE/ENTER on the projector or  ENTER on the remote control  and the 
Color Management  page is displayed.

Green, Cyan, Blue, or Magenta.
4. Press  to highlight  Hue and press  /  to select its range. Increase in the range 
will include colors consisted of more  proportions of its two adjacent colors.
Please refer to the illustration to the right for 
how the colors relate to each other.
For example, if you select Red and set its 
range at 0, only pure red in the projected 
picture will be select ed. Increasing its range 
will include red close to yellow and red close 
to magenta.

Saturation is the amount of that color in a video picture. Lower settings produce less 
saturated colors; a setting of “0” removes that  color from the image entirely. If the saturation 
is too high, that color will be overpowering and unrealistic.
6. Press   to highlight  Gain and adjust its values to your preference by pressing  / . 
The contrast level of the primary color you  select will be affected. Every adjustment 
made will reflect to the image immediately. 
7. Repeat steps 3 to 6 for other color adjustments.
