EnglishRemote control effective range
Infra-Red (IR) remote control sensor is located on the 
front of the projector. The remote control must be held at 
an angle within 30 degrees perpendicular to the 
projectors IR remote control sensor to function correctly. 
The distance between the remote control and the sensor 
should not exceed  7 meters (~ 23 feet).
Make sure that there are no obstacles between the remote 
control and the IR sensor on the projector that might 
obstruct the infra-red beam.
Replacing the remote control battery
• Avoid excessive heat and humidity. 
• There may be battery damage if th e battery is incorrectly replaced. 
• Replace only with the same or equivalent type recommended by the battery manufacturer.

EnglishPositioning 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 locati on and distance between the pr ojector 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 on a table in 
front of the screen. This is the most common way to 
position the projector for qui ck setup and portability.
2. Front Ceiling
Select this location with th e 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 on a table 
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 th e projector suspended upside-
down from the ceiling behind the screen.
Note that a special rear projection screen and the BenQ 
Projector Ceiling Mounting Ki t are required for this 
installation location.
Set  Rear Ceiling  in the SYSTEM SETUP: Basic  >

							Positioning your projector 15
EnglishObtaining 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 MP724 and  MP727. 16:10 is the native aspect ratio of 
MP735. To be able to project a complete 16: 9 (widescreen) aspect ratio image on MP724 or 
MP727, the projector can resize and scale a wi descreen image to the projectors native 
aspect width. This will result in a proportion ally 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-a ngle square) to the horizontal center of the 
screen. This prevents image distortion caus ed by angled projections (or projecting onto 
angled surfaces). 
The modern digital projector does not project di rectly 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 pos itioned 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  17, that this type of pr ojection 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 verti cal offset dimension, which are directly 
proportional to the projection distance.
BenQ has provided a table of screen sizes to as sist you in determining the ideal location for 
your projector. Refer to  MP724/727 projection dimensions on page 17/18  or MP735 
projection dimensions on page 19  depending on the projector you are using. There are two 
dimensions to consider, the perpendicular hori zontal distance from the center of the screen 
(projection distance), and the vert ical offset height of the projector from the horizontal edge 
of the screen (offset). 4:3 aspect image in a 4:3

EnglishHow to determine the positi on of the projector for a 
given screen size
1. Select your screen size.
2. Refer to the table and find the closest matc h to your screen size in the left columns 
labelled  4:3 screen . Using this value, look across th is 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 th e right column and make note of the Vertical 
offset in mm  value. This will determine the fina l 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 th e screen determined in step 2 above, and 
offset by the value determined in step 3 above.
For example (MP724), if you are using a 120-inch screen, the average projection distance is 
4999 mm and with a vertical offset of 256 mm. 
If you place the projector in a different posit ion (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 func tion to correct the distortion. See Correcting keystone 
on page 35 for details.
How to determine the recomm ended screen size for a 
given distance
This method can be used for situations wher e 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 th e physical space available in your room. 
1. Measure the distance between the project or 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. If the min and max values are 
available on the table, check that your meas ured 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 pr ojected image size of the projector at that 
projection distance.
4. On that same row, look across to th e 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 (MP724), if your measured proj ection distance was 4.5 m (4500 mm), the 
closest match in the  Average column is 4499 mm. Looking across this row shows that a 
108-inch screen is required.

When connecting a signal source to the projector, be sure to:
1. Turn all equipment off before making any connections.
2. Use the correct signal cables for each source.
3. Ensure the cables are firmly inserted. 
In the connections shown below, some cables may not be included with the projector (see 
Shipping contents on page 8 ). They are commercially available from electronics stores.
Connecting a computer or monitor
Connecting a computer
The projector provides a VGA input socket th at allows you to connect it to both IBM® 
compatibles and Macintosh® computers. A Mac adapter  (an optional accessory) is 
needed if you are connecting lega cy version Macintosh computers.
Additionally, you can also connect the projector  to a computer via the USB cable so you can 
perform paging operations of the a pplication on the PC or notebook.
To connect the projector to a notebook or desktop computer:
2. If you wish to use the remote paging function, take a USB cable and connect the 
larger end to the USB port of the computer, and the smaller end to the (USB) socket 
on the projector. See  Remote paging operations on page 44  for details.
3. If you wish to make use of the projector (m ixed mono) speakers in your presentations, 
take a suitable audio cable and connect one end of the cable to the audio output socket 
of the computer, 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 Audio Settings on page 51  for details.
The final connection path should be like  that shown in the following diagram:
• With a VGA cable: • With a DVI-I cable: • With a HDMI cable:
 Your computer 
must be equipped 
with a DVI-I output 
socket.  Your computer 
must be equipped 
with a HDMI 
output socket.
1. Take a VGA cable  and connect one end

Many notebooks do not 
turn on their external 
video ports when 
connected to a 
projector. Usually a key 
combo like FN + F3 or
