							Introduction 12
Remote control effective range
Infra-Red (IR) remote control sensors are located on 
the front and the back of the projector. The remote 
control must be held at an angle within 30 degrees 
perpendicular to the projectors IR remote control 
sensors to function correctly. The distance between 
the remote control and the sensors should not exceed 
8 meters (~ 26 feet).
Make sure that there are no obstacles between the 
remote control and the IR sensors on the projector 
that might obstruct the infra-red beam.
Replacing the remote control battery
1. Pull out the battery holder.
Please follow the illustrated instructions. Push and hold 
the locking arm while pulling out the battery holder.
2. Insert the new battery in the holder. Note the 
positive polarity should face outward.
3. Push the holder into the remote control.
• Avoid excessive heat and humidity. 
• There may be battery damage if the battery is 
incorrectly replaced. 
• Replace only with the same or equivalent type recommended by the battery manufacturer.
• Dispose of the used battery according to the battery manufacturer’s instructions.
• Never throw a battery into a fire. There may be danger of an explosion. 
• If the battery is dead or if you will not be using the remote control for a long time, remove the 
battery to prevent damage to the remote control from possible battery leakage.

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.

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 
projectors native aspect width. This will result in a proportionally smaller height equivalent 
to 75% of the projectors native aspect height.
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.
You can see from the diagram on page 16, 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 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).4:3 aspect image in a 4:3

How to determine the position of the projector for a given 
screen size
1. Select your screen size.
2. Refer to the table and find the closest match to your screen size in the left columns 
labelled 4:3 Screen Diagonal. 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 in 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 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. Measure the distance between the projector and where you want to position the 
screen. This is the projection distance.
2. Refer to the table and find the closest match to your measurement in the average 
distance from screen column labelled Average.
3. 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. On that same row, look across to the right column and make note of the Vertical 
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 
in the Average column is 4593 mm. Looking across this row shows that a 3000 mm (3 m) 
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.

Projection dimensions
Refer to Dimensions on page 58 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.

Connecting Video source devices
You can connect your projector to various Video source devices that provide any one of the 
following output sockets:
•HDMI
• Component Video
•S-Video
•Video (composite)
You need only connect the projector to a Video source device using just one of the above 
connecting methods, however each provides a different level of video quality. The method 
you choose will most likely depend upon the availability of matching terminals on both the 
projector and the Video source device as described below:
Best video quality
The best available video connection method is HDMI. HDMI (High-Definition Multimedia 
Interface) supports uncompressed video data transmission between compatible devices like 
DTV tuners, DVD players and displays over a single cable. It provides pure digital viewing 
experience.
See Connecting an HDMI device on page 20 for how to connect the projector to a HDMI 
device.
If no HDMI source is available, the next best available video connection method is 
Component Video (not to be confused with composite Video). Digital TV tuner and DVD 
players output Component Video natively, so if available on your devices, this should be 
your connection method of choice in preference to (composite) Video.
See Connecting a Component Video source device on page 21 for how to connect the 
projector to a component video device.
Better video quality
The S-Video method provides a better quality analog video than standard composite Video. 
If you have both composite Video and S-Video output terminals on your Video source 
device, you should elect to use the S-Video option.
See Connecting an S-Video source device on page 22 for how to connect the projector to 
an S-Video device.
Least video quality
Composite Video is an analog video and will result in a perfectly acceptable, but less than 
optimal result from your projector, being the least video quality of the available methods 
described here.
See Connecting a composite Video source device on page 23 for how to connect the 
projector to a composite Video device.
Connecting audio
The projector has a built-in mono speaker which is designed to provide basic audio 
functionality accompanying data presentations for business purposes only. It is not designed 
for, nor intended for stereo audio reproduction use as might be expected in home theater or 
home cinema applications. Any stereo audio input (if provided), is mixed into a common 
mono audio output through the projector speaker.

							Connection 20
Connecting an HDMI device
You should use an HDMI cable when making connection between the projector and HDMI 
devices.
To connect the projector to an HDMI device:
1. Take an HDMI cable and connect one end to the HDMI output socket of the video 
device.
2. Connect the other end of the cable to the HDMI input socket on the projector. 
3. If you wish to make use of the projector (mixed mono) speaker, take a suitable audio 
cable and connect one end of the cable to the audio output sockets of the video device, 
and the other end to the AUDIO socket of the projector.
Once connected, the audio can be controlled by the projector On-Screen Display 
(OSD) menus. See Adjusting the sound on page 39 for details.
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
connected. See Connecting audio on page 19 for details.
• In the unlikely event that you connect the projector to a DVD player via the projector’s HDMI input 
and the projected picture displays wrong colors, please change the color space to YUV. See 
Changing color space on page 28 for details.
• If no signal is detected after establishing the connection, turn off the Quick Auto Search function 
in the SOURCE menu. See Switching input signal on page 28 for details.
