11 Introduction

Positioning your projector

Choosing a location

Before choosing an installation location for your projector, take the following factors into consideration:

• Size and position of your screen

• Electrical outlet location

• Location and distance between the projector and the rest of your equipment

You can install your projector in the following ways.

1. Front Table

Select this location with the projector placed on
the table in front of the screen. This is the most
common way to position the projector for quick
setup and portability.

3. Front Ceiling

Select this location with the projector suspended
upside-down in front of the screen. Purchase the
BenQ Projector Ceiling/Wall Mount Kit from your
dealer to mount your projector.

2. Rear Table

Select this location with the projector placed on
the table behind the screen. Note that a special
rear projection screen is required.

4. Rear Ceiling

Select this location with the projector suspended
upside-down from behind the screen. Note that a
special rear projection screen and the BenQ
Projector Ceiling/Wall Mount Kit are required for
this installation location.

After turning on the projector, go to Advanced Menu - Settings > Projector Installation >
Projector Installation and press / to select a setting.

You can also use QUICK INSTALL on the remote control to access this menu.

The distance from the projector lens to the screen, the zoom setting (if available), and the video format
each factors in the projected image size.

Projection dimensions

• The screen aspect ratio is 16:9 and the projected picture is in a 16:9 aspect ratio

• *The vertical offset value is the vertical distance from the bottom edge of the image (when the projector is on a
table, diagram on the left), or top edge of the image (when the projector is ceiling mounted, diagram on the right)
to the centerline of lens.

• Due to the lens optical characteristics, every projector has its vertical offset ratio. The vertical offset value
normally gets larger while the projection distance increases.

(mm)

For example, if you are using a 80-inch screen, the recommended projection distance is 880 mm.

• If your measured projection distance is 1000 mm, the closest match in the "Projection distance (mm)"
column is 990 mm. Looking across this row shows that a 90'' (about 2.2 m) screen is required.

• All measurements are approximate and may vary from the actual sizes.
BenQ recommends that if you intend to permanently install the projector, you should physically test the
projection size and distance using the actual projector in situ 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.

• To optimize your projection quality, we suggest doing the projection by following the values in the non-gray cells.

• The values in the gray cells are for reference only.

13 Positioning your projector

Mounting the projector

Ceiling/Wall mount screw: M4
(Max L = 25 mm; Min L = 20 mm)

Unit: mm

If you intend to mount your projector, we strongly recommend that you use a proper fitting BenQ
projector mounting kit and that you ensure it is securely and safely installed.

If you use a non-BenQ brand projector mounting kit, there is a safety risk that the projector may fall
down due to an improper attachment through the use of the wrong gauge or length screws.

Before mounting the projector

• Purchase a BenQ projector mounting kit from the place you purchased your BenQ projector.

• BenQ recommends that you also purchase a separate Kensington lock compatible security cable and
attach it securely to both the Kensington lock slot on the projector and the base of the mounting
bracket. This will perform the secondary role of restraining the projector should its attachment to the
mounting bracket become loose.

• Ask your dealer to install the projector for you. Installing the projector on your own may cause it to
fall and result in injury.

• Take necessary procedures to prevent the projector from falling off such as during an earthquake.

• The warranty doesn’t cover any product damage caused by mounting the projector with a non-BenQ
brand projector mounting kit.

• Consider the surrounding temperature where the projector is ceiling/wall mounted. If a heater is used,
the temperature around the ceiling/wall may be higher than expected.

• Read the user manual for the mounting kit about the range of torque. Tightening with torque
exceeding the recommended range may cause damage to the projector and subsequently falling off.

• Make sure the power outlet is at an accessible height so that you can easily shut down the projector.

Brilliant Color

The higher the value, the brighter the image. Adjust this control so the black areas
of the image appear just as black and that detail in the dark areas is visible.

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

Lower setting produces less saturated colors. If the setting is too high, colors on
the image will be overpowering, which makes the image unrealistic.

The higher the value, the more greenish the picture becomes. The lower the value,
the more reddish the picture becomes.

This feature utilizes a new color-processing algorithm and system level
enhancements to enable higher brightness while providing truer, more vibrant
colors in picture. It enables a greater than 50% brightness increase in mid-tone
images, which are common in video and natural scenes, so the projector
reproduces images in realistic and true colors. If you prefer images with that quality,
select On.

• Normal: Maintains normal colorings for white.

• Cool: Makes images appear bluish white.

• Warm: Makes images appear reddish white.

Color Temperature Tuning

You can also set a preferred color temperature by adjusting the following options.

• R Gain/G Gain/B Gain: Adjusts the contrast levels of Red, Green, and Blue.

• R Offset/G Offset/B Offset: Adjusts the brightness levels of Red, Green, and
Blue.

Color Management

This function 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.

• Primary Color

Selects a color from among R (Red), G (Green), B (Blue), C (Cyan), M (Magenta),
or Y (Yellow).

• Hue: Increase in the range will include colors
consisted of more proportions of its two
adjacent colors. Please refer to the illustration
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.

• Saturation: Adjusts the values to your
preference. 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.

• Gain: Adjusts the values to your preference. The contrast level of the
primary color you select will be affected. Every adjustment made will reflect to
the image immediately.

White Balance

Adjusts the color temperature of white.

• R Gain/G Gain/B Gain: Adjusts the contrast levels of Red, Green, and Blue.
