Note:

There is 5% tolerance among these numbers due to optical component variations. BenQ recommends that if you intend to permanently install the projector, you should physically test the projection size and distance using the actual projector before you permanently install it, so as to make allowance for this projector's optical characteristics. This will help you determine the exact mounting position so that it best suits your installation location.

Notice (when edge blending)

- To avoid the image shaking or some pixels in the display may be misaligned, do not use the projector in the following location:

• In a building close to a construction site.
- In a room where an air conditioner unit is working and it vibrates.

- In a place where the temperature changes dramatically that may cause thermal contraction.

- Before making any adjustment, leave the projector lit for at least 45 minutes after its light source is turned on. This allows he internal temperature of the projector to stabilize.

Adjusting the Zoom/Focus

You may turn the zoom ring to zoom in or out. To focus the image, rotate the focus ring until the image is clear. The projector will focus at distances. See page 23.

Connection

Before connecting

• Before connecting, carefully read the operating instructions for connecting the external device
• Turn off the power to all devices before connecting cables.

• Take note of the following before connecting cables. Failure to do so may result in malfunctions.

• Before connecting a cable to the projector or to a device that is connected to the projector, touch any nearby metallic objects to remove any static electricity from your body.

• Do not use unnecessarily long cables to connect the projector or a device to the projector. Using a longer cable that is wound makes it act like an antenna, making it more susceptible to noise.

• When connecting cables, connect GND first and then insert the connecting terminal of the connecting device.

• Acquire any connection cables necessary to connect external devices to the system that are not supplied.

• The images on the screen may wobble if the video signal contains too much jitter. In this case, a time base corrector (TBC) must be connected.
• If synchronization signal outputs from computers or video equipment are disrupted due to changes in the video output settings or any other reasons, the colors of projected images may be temporarily disrupted.
• The projector accepts video signals, Y/C signals, YCBCR/YPBPR signals, analog RGB signals (synchronization signals are TTL level), and digital signals.
• Some computer models are not compatible with the projector.
• Use a cable compensator when you connect devices to the projector with long cables. If a cable compensator is not used, the image may not display properly.

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 projector, however, your projector supplier should 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 ENTER and the 3D Color Management page displays.

3. Highlight Primary color and press ◀/▶ to select a color from among Red, Green, Blue, Cyan, Magenta and Yellow.

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 selected. Increasing its range will include red close to yellow and red close to magenta.

1. Press ▼ to highlight Saturation and adjust its values to your preference by press ◀/▶. 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.
