• To optimize your projection quality, we suggest you do the projection within non-gray area.
• All measurements are approximate and may vary from the actual sizes.
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.
• Ceiling installation must be done by a qualified professional. Contact your dealer for more information. It is not
recommended you install the projector yourself.
• Only use the projector on a solid, level surface. Serious injury and damage can occur if the projector is dropped.
• Do not use the projector in an environment where extreme temperature occurs. The projector must be used at
temperatures between 32 degrees Fahrenheit (0 degrees Celsius) and 104 degrees Fahrenheit (40 degrees
Celsius).
• Screen damage will occur if the projector is exposed to moisture, dust or smoke.
• Do not cover the vents on the projector. Proper ventilation is required to dissipate heat. Damage to the projector
will occur if the vents are covered.
15 Installation
Page 16
Mounting the projector
If you intend to mount your projector, we strongly recommend that you use a proper fitting BenQ
projector mounting kit and that you ensure it is securely and safely installed.
If you use a non-BenQ brand projector mounting kit, there is a safety risk that the projector may fall
down due to an improper attachment through the use of the wrong gauge or length screws.
Before mounting the projector
• Purchase a BenQ projector mounting kit from the place you purchased your BenQ projector.
• BenQ recommends that you also purchase a separate security cable and attach it securely to both the
security bar on the projector and the base of the mounting bracket. This will perform the secondary
role of restraining the projector should its attachment to the mounting bracket become loose.
• Ask your dealer to install the projector for you. Installing the projector on your own may cause it to
fall and result in injury.
• Take necessary procedures to prevent the projector from falling off such as during an earthquake.
• The warranty doesn’t cover any product damage caused by mounting the projector with a non-BenQ
brand projector mounting kit.
• Consider the surrounding temperature where the projector is ceiling mounted. If a heater is used, the
temperature around the ceiling may be higher than expected.
• Read the user manual for the mounting kit about the range of torque. Tightening with torque
exceeding the recommended range may cause damage to the projector and subsequently falling off.
• Make sure the power outlet is at an accessible height so that you can easily shut down the projector.

Shifting the projection lens
The lens shift control provides flexibility for installing your projector. It allows the projector to be
positioned off the center of the screen.
The lens shift is expressed as a percentage of the projected image height or width. You can turn the
knobs on the projector to shift the projection lens in any direction within the allowable range depending
on your desired image position.
• Lens shift adjustment will not result in a degraded picture quality.
• Please stop turning the adjustment knob when you hear a clicking sound indicating that the knob has reached its
limit. Over-turning the knob may cause damage.

Adjusting the projection angle
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. You can screw the adjuster feet to
fine-tune the horizontal angle.
To retract the feet, screw the adjuster feet in a
reverse direction.
Do not look into the lens while the light source is on. The strong light from the light source may cause damage to
your eyes.
Fine-tuning the image size and clarity
1. Adjust the projected image to the size that you
need using the zoom ring.
2. Sharpen the image by rotating the focus ring.

• 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 first and then insert the connecting terminal of the connecting device.
• Many notebooks do not turn on their external video ports when connected to a projector. Usually a key combo
like FN + function key with a monitor symbol turns the external display on/off. Press FN and the labeled function
key simultaneously. Refer to your notebook's documentation to find your notebook's key combination.
• 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.
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.

• Color Temperature
• Preset: There are several preset color temperature settings available. The
available settings may vary according to the signal type selected.
You can also set a preferred color temperature by adjusting the following options.
• R Gain/G Gain/B Gain: Adjusts the contrast levels of Red, Green, and Blue.
• R Offset/G Offset/B Offset: Adjusts the brightness levels of Red, Green,
and Blue.
• Color Management
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.
• Primary Color: Selects a color from among Red, Yellow, Green, Cyan, Blue,
or Magenta.
• Hue: Increase in the range will include colors
consisted of more proportions of its two
adjacent colors. Please refer to the illustration
for how the colors relate to each other.
For example, if you select Red and set its range
at 0, only pure red in the projected picture will
be selected. Increasing its range will include red
close to yellow and red close to magenta.
• Gain: Adjusts the values to your preference.
The contrast level of the primary color you
select will be affected. Every adjustment made will reflect to the image
immediately.
• Saturation: Adjusts the values to your preference. Every adjustment made
will reflect to the image immediately. For example, if you select Red and set its
value at 0, only the saturation of pure red will be affected.
Saturation is the amount of that color in a video picture. Lower settings produce less saturated
colors; a setting of “0” removes that color from the image entirely. If the saturation is too high, that
color will be overpowering and unrealistic.

• Color Gamut
Color Gamut refers to the range of colors that can potentially be displayed by a
device. There are some standards to define difference levels of color gamuts for
display devices, such as CIE 1976, sRGB, Adobe RGB, NTSC, etc.
With this projector, selecting Auto will automatically apply the most suitable color
gamut to the image source. You can also select BT. 709, BT. 2020, or DCI-P3
according to your needs.
• CinemaMaster
• Color Enhancer: Allows you to fine-tune the saturation of colors with
larger flexibility. It modulates complex color algorithms to flawlessly render
saturated colors, fine gradients, intermediate hues and subtle pigments.
• Flesh Tone: Provides a smart adjustment of hue only for calibrating people's
skin color, not other colors in the image. It prevents discoloration of skin
tones from the light of the projection beam, portraying every skin tone in its
most beautiful shade.
• Pixel Enhancer 4K: It is a super-resolution technology which radically
enhances Full HD content in terms of colors, contrast, and textures. It's also a
Detail Enhancement Technology refines surface details for true-to-life images
that pop off the screen. Users can adjust levels of sharpness and detail
enhancement for optimal viewing.
• DCTI/DLTI: Sophisticated algorithms significantly improve color and light
output when producing images with contrasting colors or bright and dark
scales. DCTI heightens color vibrancy for drastic color transitions without
noise interference. DLTI reduces noise from fast switching of varied
luminance to optimized brightness and contrast. The result is picture quality
with the utmost picture depth and color performance.
