Ceiling 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, we strongly recommend
that you use a proper fitting BenQ
projector ceiling mount kit and that
you ensure it is securely and safely
installed.
If you use a non-BenQ brand projector
ceiling mount kit, there is a safety risk
that the projector may fall from the
ceiling due to an improper attachment
through the use of the wrong gauge or
length screws.
You can purchase a BenQ projector
ceiling 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 ceiling
mount bracket. This will perform the
secondary role of restraining the
projector should its attachment to the
mounting bracket become loose.
18. Do not place liquids near or on the
projector. Liquids spilled into the
projector may cause it to fail. If the
projector does become wet, disconnect
it from the power supply's wall socket
and call BenQ to have the projector
serviced.
19. This product is capable of displaying
inverted images for ceiling mount
installation.
Warning
Use only BenQ's Ceiling Mount Kit for
mounting the projector and ensure it is
securely installed.

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 SYSTEM SETUP: Basic >
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.

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.
4:3 is the native aspect ratio of this projector. To be able to project a complete 16:9
(widescreen) aspect ratio image, the projector can resize and scale a widescreen image to the
projector's native aspect width. This will result in a proportionally smaller height equivalent
to 75% of the projector's native aspect height.
4:3 aspect image in a 4:3
aspect display area
16:9 aspect image scaled to a 4:3 aspect
display area
Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image displayed
by this projector. This will be seen as darkened (unlit) bars along the top and bottom
(vertical 12.5% height respectively) of the 4:3 projection display area whenever displaying a
scaled 16:9 aspect image in the vertical center of the 4:3 projection display area.
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).
The modern digital projector does not project directly forward (like older style reel-to-reel
film projectors did). Instead, digital projectors are designed to project at a slightly upward
angle above the horizontal plane of the projector. This is so that they can be readily placed
on a table and will project forward and upwards onto a screen positioned so that the bottom
edge of the screen is above the level of the table (and everyone in the room can see the
screen).
If the projector is mounted on a ceiling, it must be mounted upside-down so that it projects
at a slightly downward angle.
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 directly
proportional to the projection distance.
BenQ has provided a table of 4:3-aspect-ratio 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).

How to determine the position of the projector for a given
screen size
1.
2.
Select your screen size.
Refer to the table and find the closest match to your screen size in the left columns
find the corresponding average distance from screen value in the column labelled
"Average". This is the projection distance.
3.
4.
Offset in mm" value. This will determine the final vertical offset placement of the
projector in relation to the edge of the screen.
The recommended position for the projector is aligned perpendicular to the
horizontal center of the screen, at the distance from the screen determined in step 2
For example, if you are using a 120-inch screen, the average projection distance is 4667 mm
and with a vertical offset of 183 mm.
If you place the projector in a different position (to that recommended), you will have to tilt
it down or up to center the image on the screen. In these situations, some image distortion
will occur. Use the Keystone function to correct the distortion. See "Correcting keystone" on
page 30 for details.
How to determine the recommended screen size for a
given distance
This method can be used for situations where you have purchased this projector and would
like to know what screen size will fit in your room.
The maximum screen size is limited by the physical space available in your room.
1.
2.
3.
Measure the distance between the projector and where you want to position the
screen. This is the projection distance.
Refer to the table and find the closest match to your measurement in the average
Using this value, look across that row to the left to find the corresponding screen
diagonal listed in that row. That is the projected image size of the projector at that
projection distance.
4.
Offset in mm" value. This will determine the final placement of the screen in relation
to the horizontal plane of the projector.
For example, if your measured projection distance was 4.5 m (4500 mm), the closest match
screen is required. If you can only obtain imperial sized screens, the listed screen sizes on
either side of the 3 m screen are the 9' and 10' screens.
Checking the min and max projection distance values for these screen sizes indicates that the
4.5 m measured projection distance will need to be increased to fit the 10' size screen. The
projector can be adjusted (using the zoom control) to display on these different screen sizes
at those projection distances. Be aware that these different screens have different vertical
offset values.

There is 3% 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 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.

*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
projector, however, your projector supplier should be able to provide you with suitable

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)
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:

Press Menu/Exit and then press
highlighted.

Extending lamp life
The projection lamp is a consumable item that normally can last up to 3000-4000 hours
with proper usage. To keep the lamp life as long as possible, you can do the following settings
via the OSD menu.
Setting Lamp mode as Economic
Using Economic mode reduces system noise and power consumption by 20%. If the
Economic mode is selected, the light output will be reduced and result in darker projected
pictures.
Setting the projector in Economic mode also extends the lamp operation life. To set
Economic mode, go into the SYSTEM SETUP: Advanced > Lamp Settings > Lamp mode
menu and press
/
.
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 into the 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
