Selecting a picture mode
The projector is preset with several pre-defined picture modes so that you can choose one to 
suit your operating environment and input source picture type.
The picture modes available for different types of signals are listed below.
1.Dynamic mode: Maximizes the brightness of the projected picture. This mode is 
suitable for environments where extra-high brightness is required, such as using the 
projector in well lit rooms.
2.Cinema mode: Is suitable for enjoying DVD movies best viewed in a blackened (little 
light) home cinema or lounge room environment.
3.Blackboard mode: Is designed for educational use. Images are allowed to be projected 
on a dark background, such as a blackboard instead of a normal screen. It is most 
suitable for a well lit environment with a dark background for projection.
4.User 1/User 2/User 3 mode: Recalls the settings customized based on the current 
available picture modes. See Setting the User 1/User 2/User 3 mode on page 43 for 
details.
5.Presentation mode (only for graphic input sources*): Is designed for presentations. 
The brightness is emphasized in this mode to match PC and notebook coloring.
6.sRGB mode (only for graphic input sources*): Maximizes the purity of RGB colors to 
provide true-to-life pictures regardless of brightness setting. It is most suitable for 
viewing photos taken with an sRGB compatible and properly calibrated camera, and 
for viewing PC graphic and drawing applications such as AutoCAD.
7.Standard mode (only for Video input sources**): Is appropriate for viewing colorful 
movies, video clips from digital cameras or DVs.
*Graphic input sources: Analog RGB, DVI-A, DVI-D, RJ-45
**Video input source: Component, S-Video, Video

Fine-tuning the picture quality
No matter what picture mode you have selected, you are able to fine-tune those settings to fit 
every presentation purpose. Those adjustments will be saved to the preset mode you are at 
when you exit the OSD menu.
Adjusting Brightness
Highlight Brightness in the Picture -- Basic menu and 
adjust the values by pressing  /  on the projector or 
remote control.
The higher the value, the brighter the picture. And 
lower the setting, darker the picture. Adjust this control 
so the black areas of the picture appear just as black and 
that detail in the dark areas is visible.
Adjusting Contrast
Highlight Contrast in the Picture -- Basic menu and 
adjust the values by pressing  /   on the projector or 
remote control.
The higher the value, the greater the contrast. Use this 
to set the peak white level after you have previously 
adjusted the Brightness setting to suit your selected 
input and viewing environment. 
Adjusting Color
Highlight Color in the Picture -- Basic menu and adjust the values by pressing  /   on 
the projector or remote control.
Lower setting produces less saturated colors; setting to the minimum value makes the image 
black and white. If the setting is too high, colors on the image will be overpowering, which 
makes the image unrealistic.
Adjusting Tint
Highlight Tint and adjust the values by pressing  /  on the projector or remote control.
The higher the value, the more reddish the picture becomes. The lower the value, the more 
greenish the picture becomes.

The grayscale video signal is measured in IRE units. In 
some areas which use NTSC TV standard, the grayscale 
is measured from 7.5 IRE (black) to 100 IRE (white); 
however, in other areas which use PAL equipment or 
Japanese NTSC standard, the grayscale is measured 
from 0 IRE (black) to 100 IRE (white). We suggest that 
you check the input source if it is with 0 IRE or 7.5 IRE, 
then select accordingly.

noise caused by different media players. The 
higher the setting, the less the noise. 
•Detail Enhancement: Sharpens the image. 
The higher the setting, the more details the 
image reveals.
•LT I (Luminance Transmission 
Improvement): Enhances picture brightness. 
The higher the setting, the more distinct the 
effect.
•CTI (Chroma Transmission Improvement): 
Reduces color smear. The higher the setting, 
the more distinct the effect.

*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.

Color Management
The Color Management provides six sets (RGBCMY) of colors to be adjusted to favorite 
colors. When you select each color, you can independently adjust its color range and 
saturation according to your preference.
To adjust and store the settings:
1. In the Picture -- Advanced menu, highlight Color 
Management and press ENTER. The Color 
Management page displays.
2. Highlight Primary Color and press  /  to 
select a color from among Red, Yellow, Green, 
Cyan, Blue, and Magenta.
3. Press   to highlight Range and press  /  to 
select the color range you wish to make 
adjustment. The bigger the range, the more 
proportions of its two adjacent colors the color 
contains. 
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 is 
selected. Increasing its range will include both the 
red color close to yellow and red color close to 
magenta.
4. Press   to highlight Saturation and adjusts the 
color saturation level by pressing  / . 
If you select Red and set its range at 0, only the 
saturation of the 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.
5. To leave and save the settings, press MENU once 
or EXIT twice.

the projected picture displays wrong colors, please 
change the color space to YUV.

Operating in a high altitude environment
We recommend you activate High Altitude Mode when your environment is higher than 
1500 meters (around 4920 feet) above sea level, or whenever the projector will be used for 
extended periods of time (>10 hours) without shutdown.
To  a c t i v a t e  High Altitude Mode:
1. Press MENU and then press  /  until the 
Advanced Setup menu is highlighted.
2. Press   to highlight High Altitude Mode.
3. Press  /  to select On. A confirmation 
message displays.
4. Highlight Ye s and press ENTER.
Operation under High Altitude Mode may cause a 
higher decibel operating noise level because of 
increased fan speed necessary to improve overall 
system cooling and performance.
If you use this projector under other extreme 
conditions excluding the above, it may display 
auto shut-down symptoms, which is designed to 
protect your projector from over-heating. In cases 
like this, you should switch to High Altitude 
Mode to solve these symptoms. However, this is 
not to state that this projector can operate under 
any and all harsh or extreme conditions.
Hiding the picture
In order to draw the audiences full attention to 
the presenter, you can use BLANK to hide the 
screen picture. The word BLANK appears in the 
lower right corner of the screen while the picture 
is hidden. When this function is activated with an 
audio input connected, the audio can still be 
heard.
You can set a time length in the 
System Setup > 
Blank Timer 
menu to restore the picture after a 
period of time when there is no action taken on 
the projector or remote control. The length of 
time can be set from 5 to 30 minutes in 5-minute 
increments.
If the preset time spans are not suitable for your 
personation, select Disable. 
No matter 
Blank Timer is activated or disabled, 
you can press any key (except LASER) anytime 
you want to restore the picture.
High Altitude Mode is used when the 
environment is higher than 1500m.
