Important safety instructions  
Your projector is designed and tested to meet the latest standards for safety of information  
technology equipment. However, to ensure safe use of this product, it is important that you  
follow the instructions mentioned in this manual and marked on the product.  
Safety Instructions  
1.  
Please read this manual before you  
operate your projector. Save it for  
future reference.  
4.  
In some countries, the line voltage is  
NOT stable. This projector is designed  
to operate safely within a mains  
voltage between 100 to 240 volts AC,  
but could fail if power cuts or surges  
of 10 volts occur. In areas where the  
mains voltage may fluctuate or cut  
out, it is recommended that you  
connect your projector through a  
power stabilizer, surge protector or  
uninterruptible power supply (UPS).  
2.  
Do not look straight at the projector  
lens during operation. The intense  
light beam may damage your eyes.  
5.  
Do not block the projection lens with  
any objects as this could cause the  
objects to become heated and  
deformed or even cause a fire. To  
temporarily turn off the lamp, press  
ECO BLANK on the projector or  
remote control.  
3.  
Refer servicing to qualified service  
personnel.

Safety Instructions (Continued)  
6.  
The lamp becomes extremely hot  
during operation. Allow the projector  
to cool for approximately 45 minutes  
prior to removing the lamp assembly  
for replacement.  
9.  
Do not place this product on an  
unstable cart, stand, or table. The  
product may fall, sustaining serious  
damage.  
7.  
Do not operate lamps beyond the  
rated lamp life. Excessive operation of  
lamps beyond the rated life could  
cause them to break on rare occasions.  
10. Do not attempt to disassemble this  
projector. There are dangerous high  
voltages inside which may cause death  
if you should come into contact with  
live parts. The only user serviceable  
part is the lamp which has its own  
removable cover.  
Under no circumstances should you  
ever undo or remove any other covers.  
Refer servicing only to suitably  
qualified professional service  
personnel.  
8.  
Never replace the lamp assembly or  
any electronic components unless the  
projector is unplugged.  
11. When the projector is under  
operation, you may sense some heated  
air and odor from its ventilation grill.  
It is a normal phenomenon and not a  
product defect.

16. Do not step on the projector or place  
any objects upon it. Besides probable  
physical damage to the projector, doing  
so may result in accidents and possible  
injury.  
Ceiling 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, we strongly recommend  
that you use a proper fitting BenQ  
projector ceiling mount kit and that  
you ensure it is securely and safely  
installed.  
If you use a non-BenQ brand projector  
ceiling mount kit, there is a safety risk  
that the projector may fall from the  
ceiling due to an improper attachment  
through the use of the wrong gauge or  
length screws.  
17. Do not place liquids near or on the  
projector. Liquids spilled into the  
projector may cause it to fail. If the  
projector does become wet, disconnect  
it from the power supply's power outlet  
and call BenQ to have the projector  
serviced.  
You can purchase a BenQ projector  
ceiling 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 ceiling  
mount bracket. This will perform the  
secondary role of restraining the  
projector should its attachment to the  
mounting bracket become loose.  
18. This product is capable of displaying  
inverted images for ceiling mount  
installation.  
Hg - Lamp contains mercury. Manage in  
accordance with local disposal laws.  
Use only BenQ's Ceiling Mount Kit for  
mounting the projector and ensure it is  
securely installed.  
19. This apparatus must be earthed.

Obtaining 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.  
MX850UST: For example, if you are using an 120-inch screen, the recommended projection  
distance is 1069 mm and the vertical offset is 457.2 mm.  
If your measured projection distance is 0.9 m (900 mm), the closest match in the "Distance  
from Screen in mm" column is 884 mm. Looking across this row shows that a 100'' (about  
2.5 m) screen is required.  
MW851UST: For example, if you are using an 120-inch screen, the recommended  
projection distance is 896 mm and the vertical offset is 355.4 mm.  
If your measured projection distance is 0.9 m (900 mm), the closest match in the "Distance  
from Screen in mm" column is 896 mm. Looking across this row shows that a 120'' (about  
3.0 m) screen is required.

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 projector's optical characteristics.  
This will help you determine the exact mounting position so that it best suits your  
installation location.

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 FN and the labeled function key simultaneously. Refer to your notebook's  
documentation to find your notebook's key combination.  
The D-Sub output only works when an appropriate D-Sub input is made to the COMPUTER  
1 jack.  
If you wish to use this connection method when the projector is in standby mode, make  
sure the Monitor Out function is turned on in the SYSTEM SETUP: Advanced menu. See  
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:  
Terminal name  
HDMI

Connecting audio  
The projector has one 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.  
The built-in speaker will be muted when the AUDIO OUT jack is connected.  
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 26 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 18 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.  
You can also use a microphone to output the sound through the projector speaker.  
Once connected, the audio can be controlled by the projector On-Screen Display (OSD)  
menus. See "Audio Settings" on page 47 for details.  
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 a PC signal, the projector can play the sound received from AUDIO IN 1/MIC.  
About the microphone input  
If you wish to use a microphone, connect a 3.5 mini jack cable microphone to the  
projector.  
You can use a wireless microphone as long as a wireless module is attached to the  
projector’s microphone input jack and it works well with the associated devices. To  
ensure a quality use of the wireless microphone, it is recommended that your  
microphone conforms to the specifications listed in the table below.

There are two ways to adjust microphone volumes.  
Directly set microphone volume levels in the SYSTEM SETUP: Advanced >  
Audio Settings > Microphone Volume menu.  
Press MIC/VOL keys (+/-) on the remote control.  
To make the microphone input available when the projector is in standby mode, turn on  
the SYSTEM SETUP: Advanced > Standby Settings > Microphone menu.  
If the microphone is not working, check the volume setting and cable connection.  
You might get feedback noise from the microphone when you are too close to the speaker of  
the projector. Move the microphone away from the speaker of the projector. The greater  
volume you require, the greater distance you need to be away from the speaker to prevent the  
noise.

will be overpowering, which makes the image unrealistic.  
Adjusting Tint  
The higher the value, the more reddish the picture becomes. The lower the value, the more  
greenish the picture becomes.  
Adjusting Sharpness  
The higher the value, the sharper the picture becomes. The lower the value, the softer the  
picture becomes.  
Adjusting Brilliant Color  
This feature utilizes a new color-processing algorithm and system level enhancements to  
enable higher brightness while providing truer, more vibrant colors in picture. It enables a  
greater than 50% brightness increase in mid-tone images, which are common in video and  
natural scenes, so the projector reproduces images in realistic and true colors. If you prefer  
images with that quality, select On. If you don’t need it, select Off.  
When Off is selected, the Color Temperature function is not available.  
Selecting a color temperature  
The options available for color temperature* settings vary according to the signal type  
selected.

*About color temperatures:  
There are many different shades that are considered to be "white" for various purposes. One  
of the common methods of representing white color is known as the “color temperature. A  
white color with a low color temperature appears to be reddish white. A white color with a  
high color temperature appears to have more blue in it.

3D Color Management  
In most installation situations, color management will not be necessary, such as in  
classroom, meeting room, or lounge room situations where lights remain on, or where  
building external windows allow daylight into the room.  
Only in permanent installations with controlled lighting levels such as boardrooms, lecture  
theaters, or home theaters, should color management be considered. Color management  
provides fine color control adjustment to allow for more accurate color reproduction,  
should you require it.  
Proper color management can only be achieved under controlled and reproducible viewing  
conditions. You will need to use a colorimeter (color light meter), and provide a set of  
suitable source images to measure color reproduction. These tools are not provided with the  
projector, however, your projector supplier should be able to provide you with suitable  
guidance, or even an experienced professional installer.  
The Color Management provides six sets (RGBCMY) of colors to be adjusted. When you  
select each color, you can independently adjust its range and saturation according to your  
preference.  
If you have purchased a test disc which contains various color test patterns and can be used  
to test the color presentation on monitors, TVs, projectors, etc, you can project any image  
from the disc on the screen and enter the 3D Color Management menu to make  
adjustments.  
To adjust the settings:  
1.  
2.  
Go to the PICTURE menu and highlight 3D Color Management.  
Press MODE/ENTER on the projector or remote control and the 3D Color  
Management page displays.

Maintenance  
Care of the projector  
Your projector needs little maintenance. The only thing you need to do on a regular basis is  
to keep the lens and case clean.  
Never remove any parts of the projector except the lamp. Contact your dealer if other parts  
need replacing.  
Cleaning the lens  
Clean the lens whenever you notice dirt or dust on the surface.  
Use a canister of compressed air to remove dust.  
If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner  
and gently wipe the lens surface.  
Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile  
solvent, such as alcohol, benzene, thinner or insecticide. Using such materials or  
maintaining prolonged contact with rubber or vinyl materials may result in damage to  
the projector surface and cabinet material.  
Cleaning the projector case  
Before you clean the case, turn the projector off using the proper shutdown procedure as  
described in "Shutting down the projector" on page 39 and unplug the power cord.  
To remove dirt or dust, wipe the case with a soft, lint-free cloth.  
To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH  
detergent. Then wipe the case.  
Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the  
case.  
Storing the projector  
If you need to store the projector for an extended time, please follow the instructions below:  
Make sure the temperature and humidity of the storage area are within the  
recommended range for the projector. Please refer to "Specifications" on page 58 or  
consult your dealer about the range.  
Retract the adjuster feet.  
Remove the battery from the remote control.  
Pack the projector in its original packing or equivalent.

The dimensions are based on the BenQ wall mount (P/N: 5J.J4V10.001).  
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 projector's optical characteristics.  
This will help you determine the exact mounting position so that it best suits your  
installation location.  
The dimensions supplied are offered as a guide only and may differ depending on several  
factors relating to any specific installation.  
The dimensions are based on the projector being configured with zero keystone  
correction.  
The dimensions assume that the wall mount arm is positioned 90° from the bottom case of  
projector and screen surface.
