Operating the LASER pointer
The LASER Pointer is a presentation aid 
for professionals. It emits red colored 
light when you press it and the indicator 
lights up red.
The laser beam is visible. It is necessary to 
press and hold LASER for continuous 
output. 
Do not look into the laser light 
window or shine the laser light beam on 
yourself or others. See the warning messages 
on the back of the remote control prior to 
using it.
The laser pointer is not a toy. Parents should be 
mindful of the dangers of laser energy and keep this 
remote control out of the reach of children.
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.
Making the remote control a wired control
The remote control is equipped with a jack on the top 
allowing connection to the projector with a 2.5mm 
mini jack cable available in the market. This helps you 
easily locate the remote control when needed as it is 
connected to the projector and within the distance no 
greater than the cable’s length.

  Positioning your projector
EnglishObtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, 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 15, 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

							14 Positioning your projector  
EnglishHow 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 4416 mm and with a vertical 
offset of 210 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 29 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. 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 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 4416 mm. Looking across this row shows that a 120-inch screen is required. If you can only obtain 
metric sized screens, the listed screen sizes on either side of the 120-inch screen are the 3.0 m (3000 mm) and 3.5 
m (3500 mm) screens.
Checking the min and max projection distance values for these screen sizes, indicates that the 4.5 m measured 
projection distance will also fit the 3.0 m (3000 mm) size screen. 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 projectors optical characteristics. This will help you determine the exact mounting position so that it 
best suits your installation location.

EnglishConnecting Video source devices
This section describes how to connect the projector to Video source devices using video cables. Video cable 
connections are recommended for Video presentations. 
You can connect your projector to various Video source devices that provide any one of the following output 
sockets:
•HDMI
•DVI-D
• 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. If your source device is equipped with a HDMI socket, 
you can enjoy uncompressed digital video quality.
See Connecting a HDMI source device on page 19 for how to connect the projector to a HDMI source device 
and other details.
If no HDMI source is available, the next best video signal is DVI-D. If your source device is equipped with a DVI-
D socket, you can enjoy digital video quality.
See Connecting a DVI-D source device on page 20 for how to connect the projector to a DVI-D source device 
and other details.
If no DVI-D source is available, the next best video signal is Component Video (not to be confused with 
composite Video). Digital TV tuners and DVD players output Component Video natively, so if available on your 
devices, they should be your connection method of choice in preference to S-Video or (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.
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 an S-Video or a composite Video source device on page 22 for how to connect the projector to 
an S-Video or Video device.
Connecting Audio
The projector has built-in mono speakers which are designed to provide basic audio functionality accompanying 
data presentations for business purposes only. They are 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 speakers.

  Connection
EnglishConnecting a HDMI source device
The projector provides a HDMI input socket that allows you to connect it to a HDMI source device like a DVD 
player, a DTV tuner or a display.
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 and listening experience.
Examine your source device to determine if it has an unused HDMI output socket available: 
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to a HDMI source device:
1. Take a HDMI cable and connect one end to the HDMI output socket of the HDMI source device. Connect 
the other end of the cable to the HDMI signal input socket on the projector.
Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus. See Audio 
Settings on page 44 for details.
