• 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.
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 Kensington lock compatible security cable and attach it securely to both the anti-theft lock slot 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/wall 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. V: Height of projected image
H: Width of projected image
To reach the highest or lowest projection position:

1. Turn (Up/Down).
2. When you feel it is reaching the limit, turn (Left/Right) to the left or right and turn again.
3. Repeat the step above until finding the suitable position you need.

• 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.

Adjusting the projected image
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
Adjust the projected image to the size that you need using the zoom ring.Sharpen the image by rotating the focus ring.
Correcting keystone
Keystoning refers to the situation where the projected image becomes a trapezoid due to angled projection.

See Reference Mode on page 36.
Reference Mode	There are 2 user-definable modes if the current available picture modes are not suitable for your need. You can use one of the picture modes (except the User 1/User 2) as a starting point and customize the settings. 1. Go to Picture > Picture Mode. 2. Press / to select User 1 or User 2. 3. Press to highlight Reference Mode, and press /  to select a picture mode that is closest to your need. 4. Press to select a menu item to be changed and adjust the value. The adjustments define the selected user mode.
Brightness	The higher the value, the brighter the image. Adjust this control so the black areas of the image appear just as black and that detail in the dark areas is visible.
Contrast	The higher the value, the greater the contrast. Use this to set the peak white level after you have previously adjusted the Brightness setting to suit your selected input and viewing environment.
Color	Lower setting produces less saturated colors. If the setting is too high, colors on the image will be overpowering, which makes the image unrealistic.
Tint	The higher the value, the more greenish the picture becomes. The lower the value, the more reddish the picture becomes.
Sharpness	The higher the value, the sharper the picture becomes.
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 a desired level. When 0 is selected, the Color Temperature function is not available.
Advanced Color Settings	Gamma Selection Gamma refers to the relationship between input source and picture brightness. • 1.8/2.0/2.1/BenQ/DICOM: Select these values according to your preference. • 2.2/2.3: Increases the average brightness of the picture. Best for a lit environment, meeting room or family room. • 2.4/2.5: Best for viewing movies in a dark environment. • 2.6: Best for viewing movies which are mostly composed of dark scenes.
	HDR Brightness The projector can automatically adjust the brightness levels of your image according to the input source. You can also manually select a brightness level to display better picture quality. When the value is higher, the image becomes brighter; when the value is lower, the image becomes darker.
	Color Temperature There are several preset color temperature settings available. The available settings may vary according to the signal type selected. • Normal: Maintains normal colorings for white. • Cool: Makes images appear bluish white. • Warm: Makes images appear reddish white.
	Color Temperature Tuning 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.
Advanced Color Settings	Color Management This function 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 R (Red), G (Green), B (Blue), C (Cyan), M (Magenta), or Y (Yellow). • Hue: Hue is used for adjusting the color balance. Increase in the value will include colors consisted of more proportions of its adjacent colors in counterclockwise order. Decrease in the value will have effect in clockwise order. Please refer to the illustration for how the colors relate to each other For example, if you select Red and set its value at 0, only pure red in the projected picture will be selected. Increasing its value will include red close to yellow while decreasing its value will include red close to magenta.• 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 olors; a setting of “0” removes that color from the image entirely. If the saturation is too high, that color will be overpowering and unrealistic. • 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. Magenta RED BLUE Yellow Cyan GREEN
	White Balance Color temperature of white can be modified by adjusting the red/green/blue gain.
	Wall Color Corrects the projected picture’s color when the projection surface such as a painted wall which may not be white, the Wall Color feature can help correct the projected picture’s colors to prevent possible color difference between the source and projected pictures. There are several precalibrated colors to choose from: Light Yellow, Pink, Light Green, Blue, and Blackboard.
Reset Picture	Returns all of the adjustments you’ve made for the Picture menu to the factory preset values.

Display

Aspect Ratio	There are several options to set the image’s aspect ratio depending on your input signal source. • Auto: Scales an image proportionally to fit the projector’s native resolution in its horizontal or vertical width.• Real: Projects an image as its original resolution and resizes it to fit within the display area. For input signals with lower resolutions, the projected image will be displayed in its original size.• 4:3: Scales an image so that it is displayed in the center of the screen with a 4:3 aspect ratio.• 16:9: Scales an image so that it is displayed in the center of the screen with a 16:9 aspect ratio.• 16:10: Scales an image so that it is displayed in the center of the screen with a 16:10 aspect ratio.• 2.4:1: Scales an image so that it is displayed aligned with the upper edge of the display region with a 2.4:1 aspect ratio.

Light source information
Getting to know the light source hour
When the projector is in operation, the duration (in hours) of light source usage is automatically calculated by the built-in timer. The method of calculating the equivalent light source hour is as follows:
Light source Usage Time = (hours used in Normal mode) + (hours used in ECO mode) + (hours used in Dimming mode) + (hours used in Custom mode)
Total (equivalent) light source hour = 1.0 x (hours used in Normal mode) + 1.0 x (hours used in ECO mode) + 1.0 x (hours used in Dimming mode) + 1.0 x (hours used in Custom mode)
To obtain the light source hour information:

1. Go to Advanced Menu – Settings > Light Settings and press OK. The Light Settings page appears.
2. Press to select Light Usage Time and press OK. The Light Usage Time information is displayed.
   You can also get the light source hour information on the Information menu.

Extending light source life

• Setting the Light Mode
  Go to Advanced Menu – Settings > Light Settings > Light Mode and select a suitable light source power from among the provided modes. Setting the projector in ECO, Dimming or Custom mode extends light source life.

  Light Source mode	Description
  Normal	Provides full light source brightness
  ECO	Lowers brightness to extend the light source life and decreases the fan noise
  Dimming	Lowers brightness to offer a longer light source life
  Custom	Enables the light source brightness adjustment bar so that you can adjust the setting to your liking

• Setting Auto Power Off
  This function allows the projector to turn off automatically if no input signal is detected after a set period of time to prevent unnecessary waste of light source life. To s e t Auto Power Off, go to Advanced Menu – Settings > Operation Settings > Power
  On/Off Settings > Auto Power Off and press / .
• The apparent brightness of the projected image will vary depending on the ambient lighting conditions, selected input signal contrast/brightness settings, and is directly proportional to projection distance.
• The light source brightness will decline over time and may vary within the light source manufacturers specifications. This is normal and expected behavior.
