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.

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.
Set Rear Table in the SYSTEM SETUP: Basic > 
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 SYSTEM SETUP: Basic > 
Projector Position menu after you turn the projector on.

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 17, 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).

How to determine the position of the projector 
for a given screen size
1. Select your screen size.
2. Refer to the table on page 17 and find the closest match to your screen size in the 
left columns labelled Screen size. Using this value, look across this row to the right 
to find the corresponding average distance from screen value in the column labelled 
Average. This is the projection distance.
3. On that same row, look across to the right column and make note of the Vertical 
offset (mm) value. This will determine the final vertical offset placement of the 
projector in relation to the edge of the screen.
4. 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 
above, and offset by the value determined in step 3 above.
For example, if you are using this projector and a 120-inch screen, the average projection 
distance is 3894 mm and with a vertical offset of 251 mm.
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. Measure the distance between the projector and where you want to position the 
screen. This is the projection distance.
2. Refer to the table on page 17 and find the closest match to your measurement in the 
average distance from screen column labelled Average. Check that your measured 
distance is between the min and max distances listed on either side of the average 
distance value.
3. Using this value, look across that row to the left to find the corresponding Screen 
size listed in that row. That is the projected image size of the projector at that 
projection distance.
4. On that same row, look across to the right column and make note of the Vertical 
offset (mm) value. This will determine the final placement of the screen in relation 
to the horizontal plane of the projector. 
For example, if you are using this projector and your measured projection distance is 4.0 m 
(4000 mm), the closest match in the Average column is 3894 mm. Looking across this 
row shows that a 120-inch screen is required.
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 27 on page for details.

Projection dimensions
Refer to Dimensions on page 70 for the center of lens dimensions of this projector 
before calculating the appropriate position.
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 projectors optical characteristics. This will help you 
determine the exact mounting position so that it best suits your installation location.
