 Mounting the projector
We want you to have a pleasant experience using your BenQ projector, so we
need to bring this safety matter to your attention to prevent possible damage to
person and property.
If you intend to mount your projector on the ceiling or wall, we strongly
recommend that you use a proper fitting BenQ projector ceiling mount kit or
wall mount 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 from the ceiling or wall due to an improper attachment
through the use of the wrong gauge or length screws.
You can purchase a BenQ projector ceiling mount or wall mount 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.

Introduction 15
Positioning your projector
Choosing a location
Your room layout or personal preference will dictate which installation location you
select. Take into consideration the size and position of your screen, the location of a
suitable power outlet, as well as the location and distance between the projector and
the rest of your equipment.

Your projector is designed to be installed in one of four possible installation locations:

1. Front Table
Select this location with the projector placed near the
floor in front of the screen. This is the most common
way to position the projector for quick setup and
portability.

2. Front Ceiling
Select this location with the projector suspended
upside-down from the ceiling in front of the screen.
Purchase the BenQ Projector Ceiling Mounting Kit
from your dealer to mount your projector on the
ceiling.
Set Front Ceiling in the Projector Position* menu
after you turn the projector on.
3. Rear Table
Select this location with the projector placed near the
floor behind the screen.
Note that a special rear projection screen is required.
Set Rear Table in the Projector Position* menu
after you turn the projector on.
4. Rear Ceiling
Select this location with the projector suspended
upside-down from the ceiling behind the screen.
Note that a special rear projection screen and the
BenQ Projector Ceiling Mounting Kit are required for
this installation location.
Set Rear Ceiling in the Projector Position* menu
after you turn the projector on.

*There are two menu types for your selection. One is Basic, and the other is
Advanced. From the Basic menu, you can select Projector Position when the
projector is without input signal. From the Advanced menu, you can select
Projector Position in the System Setup: Basic menu. See "Using the menus" on page
28 for details.

16 Positioning your projector

Obtaining a preferred projected image size
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.
The projector should always be placed horizontally level (like flat on a table), and
positioned directly perpendicular (90° right-angle square) to the horizontal center of
the screen. This prevents image distortion caused by angled projections (or projecting
onto angled surfaces).
If the projector is mounted on a ceiling, it must be mounted upside-down so that it
projects at a slightly downward angle.
You can see from the diagram on page 18, that this type of projection causes the
bottom edge of the projected image to be vertically offset from the horizontal plane
of the projector. When ceiling mounted, this refers to the top edge of the projected
image.
If the projector is positioned further away from the screen, the projected image size
increases, and the vertical offset also increases proportionately.
When determining the position of the screen and projector, you will need to account
for both the projected image size and the vertical offset dimension, which are
proportional to the projection distance.
BenQ has provided a table of screen sizes to assist you in determining the ideal
location for your projector. There are two dimensions to consider, the perpendicular
horizontal distance from the center of the screen (projection distance), and the
vertical offset height of the projector from the horizontal edge of the screen (offset).

300 7620 6642 3736 9940 10970 12000 598

For example, If you are using a 60-inch screen, the projection distance is 2194 mm and
with a vertical offset of 120 mm.
If your measured projection distance is 5.5 m (5500 mm), the closest match in the
"Distance from screen (mm)" column is 5485 mm. Looking across this row shows that a
150'' (about 3810 mm) 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.

Any other resolutions will be scaled by the projector depending upon the 'aspect
ratio' setting, which may cause some image distortion or loss of picture clarity.
See "Selecting the aspect ratio" on page 34 for details.

Selecting the aspect ratio

The 'aspect ratio' is the ratio of the image width to the image height.
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 (no matter what aspect the source is):
1. Open the OSD menu and make sure the Menu Type is Advanced. See "Using
the menus" on page 28 for details.
2. Go to the Display > Aspect Ratio menu.
3. Press / to select an aspect ratio to suit the format of the video signal and
your display requirements.

34 Operation
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

projector's native resolution in its horizontal or
vertical width. This is suitable for the incoming
image which is neither in 4:3 nor 16:9 and you 4:3 picture
want to make most use of the screen without
altering the image's aspect ratio.

16:9 picture
2. 4:3: Scales a picture so that it is displayed in the
center of the screen with a 4:3 aspect ratio. This is
most suitable for 4:3 pictures like computer
monitors, standard definition TV and 4:3 aspect 4:3 picture
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, 16:9 picture
as it displays them without aspect alteration.
4. Wide: Stretches the picture horizontally in a non-
linear manner, that is, the edges of the picture are
stretched more than the center of the picture to
prevent distortion of the central part of the 4:3 picture
picture. This is suitable for occasions where you
want to stretch the width of a 4:3 aspect picture to the width of a 16:9 aspect screen.
It does not alter the height. Some widescreen movies have been produced with their
width squashed down to the width of a 4:3 aspect, and are best viewed when
restretched back to their original width using this setting.
5. Letter Box (LB): Scales a picture to fit the
projector’s native resolution in its horizontal width
and resize the picture’s height to the 3/4 of the
projection width. This may produce a picture 16:9 picture
greater in height than can be displayed, so part of
the picture is lost (not displayed) along the top and
bottom edges of the projection. This is suitable for
the display of movies which are presented in letter
box format (with black bars on the top and Letter Box
bottom). format picture

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 adjusent 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 Color Management menu to

Maintenance
Care of the projector
Your projector needs little maintenance. The only thing you need to do on a regular
basis is to keep the lens and case clean.
Never remove any parts of the projector except the lamp. Contact your dealer if other
parts need replacing.

Cleaning the lens

Clean the lens whenever you notice dirt or dust on the surface.
• Use a canister of compressed air to remove dust.
• If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens
cleaner and gently wipe the lens surface.
• Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or
volatile solvent, such as alcohol, benzene, thinner or insecticide. Using such
materials or maintaining prolonged contact with rubber or vinyl materials may
result in damage to the projector surface and cabinet material.
Never rub the lens with abrasive materials.

Cleaning the projector case

Before you clean the case, turn the projector off using the proper shutdown
procedure as described in "Shutting down the projector" on page 45 and unplug the
power cord.
• To remove dirt or dust, wipe the case with a soft, lint-free cloth.
• To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral
pH detergent. Then wipe the case.
Never use wax, alcohol, benzene, thinner or other chemical detergents. These can
damage the case.

Storing the projector

If you need to store the projector for an extended time, please follow the instructions
below:
• Make sure the temperature and humidity of the storage area are within the
recommended range for the projector. Please refer to "Specifications" on page 70
or consult your dealer about the range.
• Retract the adjuster feet.
• Remove the battery from the remote control.
• Pack the projector in its original packing or equivalent.

Transporting the projector

It is recommended that you ship the projector with its original packing or equivalent.

60 Maintenance
Lamp information
Getting to know the lamp hour
When the projector is in operation, the duration (in hours) of lamp usage is
automatically calculated by the built-in timer. The method of calculating the equivalent
lamp hour is as follows:
Total (equivalent) lamp hour
= 1 (hours used in Economic mode) + 4/3 (hours used in normal mode)
See "Setting Lamp Power" below for more information on Economic mode.

The lamp hour in Economic mode is calculated as 3/4 of that in Normal mode. That is,
using the projector in Economic mode helps to extend the lamp hour by 1/3.
To obtain the lamp hour information:
1. Open the OSD menu and go to the Advanced menu > System Setup:
Advanced > Lamp Settings menu. Press OK on the projector or remote
control.
2. Select Lamp Timer and press OK on the projector or remote control.
3. You will see the Equivalent Lamp Hour information displaying on the menu.
4. To leave the menu, press MENU on the projector or remote control.
You can also get the lamp hour information on the Information menu.

Extending lamp life

The projection lamp is a consumable item. To keep the lamp life as long as possible,
you can do the following settings via the OSD menu or remote control.
Setting Lamp Power
Using Economic/SmartEco mode will reduces system noise and power
consumption. If the Economic/SmartEco mode is selected, the light output will be
reduced and result in darker projected pictures, the projector protected for longer
working life.
Setting the projector in Economic/SmartEco mode also extends the lamp
operation life. To set Economic/SmartEco mode, go to the Advanced menu >
Picture > Lamp Power menu and press / .

The lamp modes are defined as the chart below:

Lamp Power Description
Normal Provides full lamp brightness
Lower brightness to extend the lamp life and decreases the fan

Maintenance 61
 Setting Auto Power Off
This function allows the projector to turn off automatically if no input source is
detected after a set period of time to prevent unnecessary waste of lamp life.
To set Auto Power Off, go to the Advanced menu > System Setup: Basic >
Auto Power Off menu and press / . The time period can be set from 5 to 30
minutes in 5-minute increments. If the preset time lengths are not suitable for your
presentation, select Disable. The projector will not automatically shut down in a
certain time period.

62 Maintenance
Timing of replacing the lamp
When the Lamp indicator lights up red or a message appears suggesting it is time to
replace the lamp, please install a new lamp or consult your dealer. An old lamp may
cause a malfunction in the projector and in some instances the lamp may explode.
The Lamp indicator light and Temperature warning light will light up if the lamp
becomes too hot. See "Indicators" on page 67 for details.

The following lamp warning displays will remind you to change the lamp.
The warning messages below are for reference only. Please follow the actual on-
screen instructions to prepare and replace the lamp.

Status Message
It is strongly recommended that you replace
the lamp at this stage. The lamp is a
consumable item. The lamp brightness
diminishes with use. This is normal lamp
behavior. You can replace the lamp whenever
you notice that the brightness level has
significantly diminished.

The lamp MUST be replaced before the

projector will operate normally.

lamp socket to avoid any possible injury or damage to the human eyes
caused by fractured lamp.

• To reduce the risk of electrical shock, always turn the projector off and
disconnect the power cord before changing the lamp.

• To reduce the risk of severe burns, allow the projector to cool for at
least 45 minutes before replacing the lamp.

• To reduce the risk of injuries to fingers and damage to internal

components, use caution when removing lamp glass that has shattered
into sharp pieces.

• To reduce the risk of injuries to fingers and/or compromising image

quality by touching the lens, do not touch the empty lamp comparent
when the lamp is removed.
