Bench Mx750/mp780st Digital Projector User Manual

							Operation 41 The options available for color temperature* settings vary according to the signal type 
selected.
1.T1: With the highest color temperature, T1 makes the image appear the most bluish 
white than other settings.
2.T2: Makes images appear bluish white.
3.T3: Maintains normal colorings for white.
4.T4: Makes images appear reddish white.
*About color temperatures:
There are many different shades that are considered to be white for various purposes. One 
of the common methods of representing white color is known as the “color temperature”. A 
white color with a low color temperature appears to be reddish white. A white color with a 
high color temperature appears to have more blue in it.
3D Color Management
In most installation situations, color management will not be necessary, such as in 
classroom, meeting room, or lounge room situations where lights remain on, or where 
building external windows allow daylight into the room. 
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 allow for more accurate color reproduction, 
should you require it.
Proper color management can only be achieved under controlled and reproducible viewing 
conditions. You will need to use a colorimeter (color light meter), and provide a set of 
suitable source images to measure color reproduction. These tools are not provided with the 
p ro j e c to r,  h ow e ve r,  yo u r  p ro j e c to r  s u p p l i e r  s hould be able to provide you with suitable 
guidance, or even an experienced professional installer.
The Color Management provides six sets (RGBCMY) of colors to be adjusted. When you 
select each color, you can independently adjust its range and saturation according to your 
preference.
If you have purchased a test disc which contains various color test patterns and can be used 
to test the color presentation on monitors, TVs, projectors, etc. You can project any image 
from the disc on the screen and enter the 3D Color Management menu to make 
adjustments.
To adjust the settings:
1. Go to the PICTURE menu and highlight 3D Color Management.
2. Press MODE/ENTER and the 3D Color Management page displays.
3. Highlight Primary Color and press  /  to select a color from among Red, Yellow, 
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. 
						

							Operation 42Please 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 selected. Increasing its range 
will include red close to yellow and red close 
to magenta.
5. Press  to highlight Saturation and adjust 
its values to your preference by pressing  /
. Every adjustment made will reflect to the 
image immediately.
For example, if you select Red and set its 
value at 0, only the saturation of pure red will be affected.
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.
8. Make sure you have made all of the desired adjustments.
9. Press MENU/EXIT to exit and save the settings.
Creating your own startup screen
In addition to selecting the projector preset startup screen from among BenQ logo, Black or 
Blue screen, you can make your own startup screen that is an image projected from your 
computer or video source.
1. Project the image you want to use as your 
startup screen from either a computer or video 
source.
2. Press CAPTURE on the remote control or go 
to the SYSTEM SETUP: Basic > MyScreen 
menu, press MODE/ENTER.
3. A confirmation message displays. Press 
CAPTURE or MODE/ENTER again.
4. The message Screen Capturing... displays 
while the projector is processing the image. 
Please wait.
5. If the action is successful, you see the message Captured Succeeded on the screen. The 
captured image is saved as MyScreen.
6. To view the captured image displayed as the startup screen, set MyScreen in the 
SYSTEM SETUP: Basic > Splash Screen menu and restart the projector.
In the unlikely event, the capturing action failed. If so, change your target image.

SYSTEM SETUP: 
Basic > Operation Settings > Blank Timer menu to let the projector return the image 
automatically after a period of time when there is no action taken on the blank screen. The 
length of time can be set from 5 to 30 minutes in 5-minute increments.
• Do not block the projection lens from projecting as this could cause the blocking object to 
become heated.
