							Positioning your projector 21
MW727
The screen aspect ratio is 16:10 and the projected picture is 16:10. 
There is 5% 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 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.

Connection
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 9). They are commercially available from electronics stores.  
Many notebooks do not turn on their external video ports when connected to a projector. 
Usually a key combo like FN + F3 or CRT/LCD key turns the external display on/off. Locate a 
function key labeled CRT/LCD or a function key with a monitor symbol on the notebook. Press

Connecting video source devices
You need only connect the projector to a video source device using just one of the 
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:
Connecting audio
The projector has one built-in mono speaker 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 speaker.
The built-in speaker will be muted when the AUDIO OUT jack is connected.
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
connected. See Connecting audio on page 23 for details.
• If the selected video image is not displayed after the projector is turned on and the correct 
video source has been selected, check that the video source device is turned on and 
operating correctly. Also check that the signal cables have been connected correctly.

Playing sound through the projector
You can make use of the projector (mixed mono) speaker in your presentations, and also 
connect separate amplified speakers to the AUDIO OUT socket of the projector.
If you have a separate sound system, you will most likely want to connect the audio output 
of your Video source device to that sound system, instead of to the mono audio projector.
Once connected, the audio can be controlled by the projector On-Screen Display (OSD) 
menus.
The table below describes the connection methods for different devices, and where the 
sound is from.

The selected input signal determines which sound will be played by the projector speaker, and 
which sound will be output from the projector when AUDIO OUT is connected. If you select the 
COMPUTER/PC signal, the projector can play the sound received from AUDIO IN mini jack. If you 
select the COMPONENT/VIDEO signal, the projector can play the sound received from 
AUDIO (L/R).

Operation
Starting up the projector
1. Remove the lens cap.
2. Plug the power cord into the projector and into a 
wall socket. Turn on the wall socket switch 
(where fitted). Check that the POWER 
indicator light on the projector lights orange 
after power has been applied.
Please use the original accessories (e.g. power cable) only 
with the device to avoid possible dangers such as electric 
shock and fire.
3. Press POWER on the projector   or remote control   to start the projector 
and a start up tone sounds. The POWER indicator light flashes green and stays 
green when the projector is on.
The start up procedure takes about 30 seconds. In the later stage of start up, a 
startup logo is projected.
(If necessary) Rotate the focus ring to adjust the image clearness.
To turn off the ring tone, see Turning off the Power on/off ring tone on page 43 for 
details.
If the projector is still hot from previous activity, it will run the cooling fan for approximately 90 
seconds before energizing the lamp.
4. To use the OSD menus, please set them to 
your familiar language first.
5. If you are prompted for a password, press 
the arrow keys to enter a six digit 
password. See Utilizing the password 
function on page 30 for details.
6. Switch all of the connected equipment on.
7. The projector will start to search for input 
signals. The current input signal being scanned displays in the upper left corner of the 
screen. If the projector doesnt detect a valid signal, the message No Signal will 
continue displaying until an input signal is found.
You can also press SOURCE on the projector or remote control to select your 
desired input signal. See Switching input signal on page 33 for details.
If the frequency/resolution of the input signal exceeds the projectors operating range, you will 
see the message Out of Range displayed on a blank screen. Please change to an input signal 
which is compatible with the projectors resolution or set the input signal to a lower setting. See 
Timing chart on page 70 for details.
To maintain the lamp life, once you turn the projector on, wait at least 5 minutes before turning 
if off.

Adjusting the projected image
Adjusting the projection angle
The projector is equipped with 1 front adjuster foot and 1 rear adjuster foot. These 
adjusters change the image height and projection angle. To adjust the projector:
1. Screw the front adjuster foot. Once the image 
is positioned where you want it. 
2. Screw the rear adjuster foot to fine tune the 
horizontal angle.
To retract the foot. Screw the front and rear 
adjuster foot in a reverse direction.
If the projector is not placed on a flat surface or the 
screen and the projector are not perpendicular to 
each other, the projected image becomes 
trapezoidal. To correct this situation, see 
Correcting 2D Keystone on page 27 for details.
• Do not look into the lens while the lamp is on. The strong light from the lamp may cause 
damage to your eyes.
• Be careful when you press the adjuster button as it is close to the exhaust vent where hot air 
comes from.
Auto-adjusting the image
In some cases, you may need to optimize the picture quality. To do this, press AUTO on 
the projector or remote control. Within 3 seconds, the built-in Intelligent Auto 
Adjustment function will re-adjust the values of Frequency and Clock to provide the best 
picture quality. 
The current source information will be displayed in the upper left corner of the screen for 
3 seconds. 
• The screen will be blank while AUTO is functioning.
• This function is only available when PC signal (analog RGB) is selected.
