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.

General safety instruction

1. Do not look straight at the projector lens during operation. The intense light beam may

damage your eyes.

2. Always open the lens shutter or remove the lens cap when the projector light source is on.

3. 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 uctuate or cut out, it is recommended

that you connect your projector through a power stabilizer, surge protector or uninterruptible

power supply (UPS).

4. Do not block the projection lens with any objects when the projector is under operation

as this could cause the objects to become heated and deformed or even cause a re. To

temporarily turn off the light source, press ECO BLANK on the remote control.

5. Do not place this product on an unstable cart, stand, or table. The product may fall, sustaining

serious damage.

6. 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.

Under no circumstances should you ever undo or remove any other covers. Refer servicing

only to suitably qualied professional service personnel.

7. Do not place this projector in any of the following environments.

• Space that is poorly ventilated or conned. Allow at least 50 cm clearance from walls and

free ow of air around the projector.

• Locations where temperatures may become excessively high, such as the inside of a car

with all windows rolled up.

• Locations where excessive humidity, dust, or cigarette smoke may contaminate optical

components, shortening the projector's life span and darkening the image.

• Locations near re alarms

• Locations with an ambient temperature above 40°C / 104°F

• Locations where the altitudes are higher than 3000 m (10000 feet).

8. Do not block the ventilation holes.

• Do not place this projector on a blanket, bedding or any other soft surface.

• Do not cover this projector with a cloth or any other item.

• Do not place inammables near the projector.

If the ventilation holes are seriously obstructed, overheating inside the projector may result in

a re.

9. 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.

10. 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 wall socket and

call BenQ to have the projector serviced.

This equipment has a three-pin grounding-type power plug. Do not

remove the grounding pin. As a safety feature, this plug will only t a grounding-type power outlet. If you are unable to t the plug into the

Do not remove

outlet, contact an electrician.

Operating the LASER pointer

The Laser Pointer is a presentation aid for professionals. It emits a beam of red light when you press it. The laser beam is visible. It is necessary to press and hold LASER for continuous output.

Caution:

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.

English

Remote control effective range

Infra-Red (IR) remote control sensor is located on the front and rear of the projector. The remote

control must be held at an angle within 30 degrees perpendicular to the projector's IR remote control sensor to function correctly. The distance between the remote control and the sensor

should not exceed 8 meters (~ 26 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.

Approx. ±30°

Replacing the remote control battery

1. To open the battery cover, turn the remote control over to view its back, push on the nger grip on the cover and slide it up in the direction of the arrow as illustrated. The cover will slide off.

2. Remove any existing batteries (if necessary) and install two AAA batteries observing the

battery polarities as indicated in the base of the battery compartment. Positive (+) goes to positive and negative (-) goes to negative.

3. Ret the cover by aligning it with the base and sliding it back down into position. Stop when it clicks into place.

Caution:

• 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 re. 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.

Note:

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

• To optimize the projection quality, we suggest to project images in an area without grayscale.

Adjusting by Lens shift

Horizontal lens shift lever

Vertical lens shift lever

The Lens Shift function can be used to adjust the position of the projected image either horizontally or vertically within the range detailed below.

Adjusting the vertical image position

English

The vertical image height can be adjusted between 121% +12.3%/-2.2% for LX785 and 115% +10%/-2% for LU785 of offset position. Please consult the Lens Shift Range diagram below for further clarication.

Adjusting the horizontal image position

With the lens in the center position the horizontal image position can be adjusted between +/-3.2% for LX785 and +/-2.5% for LU785. Please consult the Lens Shift Range diagram below for further clarication.

Note:

Image quality is assured only within the listed lens shift range.

Caution:

• If you hear a “clicking sound” during the adjustment, it means that the knob is past its adjustment limit. Please stop

adjusting it, in order to avoid any unexpected damage, and turn the knob in the opposite direction, at least to one step before the click.

• If you can’t turn it back, please press and turn the knob back at same time.

Connection

Before connecting

• Before connecting, carefully read the operating instructions for connecting the external device

• Turn off the power to all devices before connecting cables.

• Take note of the following before connecting cables. Failure to do so may result in

malfunctions.

• Before connecting a cable to the projector or to a device that is connected to the

projector, touch any nearby metallic objects to remove any static electricity from your body.

• Do not use unnecessarily long cables to connect the projector or a device to the projector.

Using a longer cable that is wound makes it act like an antenna, making it more susceptible to noise.

• When connecting cables, connect GND rst and then insert the connecting terminal of the

connecting device.

• Acquire any connection cables necessary to connect external devices to the system that are not supplied.

• The images on the screen may wobble if the video signal contains too much jitter. In this case, a time base corrector (TBC) must be connected.

• If synchronization signal outputs from computers or video equipment are disrupted due to

changes in the video output settings or any other reasons, the colors of projected images may be temporarily disrupted.

• The projector accepts video signals, Y/C signals, YCBCR/YPBPR signals, analog RGB signals (synchronization signals are TTL level), and digital signals.

• Some computer models are not compatible with the projector.

• Use a cable compensator when you connect devices to the projector with long cables. If a

cable compensator is not used, the image may not display properly.

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.

Note:

• The projector is only capable of playing mixed mono audio, even if a stereo audio input is connected. See

"Connecting audio" on page 27 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 amplied 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.

Device PC Component/Video HDMI-1/HDMI-2

Audio input port AUDIO IN (mini jack) AUDIO (L/R) HDMI

The projector can play the sound from...

Audio output port AUDIO OUT AUDIO OUT AUDIO OUT

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 PC signal,

the projector can play the sound received from AUDIO IN mini jack. If you select the VIDEO signal, the

projector can play the sound received from AUDIO (L/R).

AUDIO IN (mini jack) AUDIO (L/R) HDMI

Connecting smart devices

The projector can also project the content directly from your personal device(phone, tablet, NB) through optional BenQ wireless solution such as Qcast dongle or InstaShow™. Please consult to your local agent if you're interested 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 ne 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.

RED Yellow GREEN

To adjust the settings:

1. Go to the Picture menu and highlight 3D Color

Management.

2. Press ENTER and the 3D Color Management page

displays.

3. Highlight Primary color and press ◄/► to select a

5. Press ▼ to highlight Saturation and adjust its values to your preference by press ◄/►.

Every adjustment made will reect to the image immediately.
