Important safety instructions 6 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. 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. Hg - Lamp contains mercury. Manage in accordance with local disposal laws. See lamprecycle.org.

Introduction 12 Positioning your projector Choosing a location Your projector is designed to be installed in one of four possible installation locations:

1. Front Table Select this location with the projector placed on the table in front of the screen. This is the most common way to position the projector for quick setup and portability. 2. Front Ceiling Select this location with the projector suspended upside-down from the ceiling in front of the screen. Purchase the BenQ Projector Ceiling Mount Kit from your dealer to mount your projector on the ceiling. Set Front Ceiling in the SYSTEM SETUP: Basic > Projector Installation menu after you turn the projector on. 3. Rear Ceiling Select this location with the projector suspended upside-down from the ceiling behind the screen. Note that a special rear projection screen and the BenQ Projector Ceiling Mount Kit are required for this installation location. 4. Rear Table Select this location with the projector placed on the table behind the screen. Note that a special rear projection screen is required.

Your room layout or personal preference will dictate which installation location you select. Take into consideration the size and position of your screen, the location of a suitable power outlet, as well as the location and distance between the projector and the rest of your equipment. Set Rear Ceiling in the SYSTEM SETUP: Basic > Projector Installation menu after you turn the projector on. Set Rear Table in the SYSTEM SETUP: Basic > Projector Installation menu after you turn the projector on. Positioning your projector 13 Positioning 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. Projection dimensions Refer to "Dimensions" on page 54 for the center of lens dimensions of this projector before calculating the appropriate position. 4:3 Screen diagonal The screen aspect ratio is 4:3 and the projected picture is in a 4:3 aspect ratio For example, if you are using an 150-inch screen, the recommended projection distance is 6264 mm and the vertical offset is 229 mm. If your measured projection distance is 5.0 m (5000 mm), the closest match in the "Distance from screen (mm)" column is 5011 mm. Looking across this row shows that a 120'' (about 3.05 m) screen is required. 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. 14your projector Screen Vertical offset Center of lens H W Projection distance Screen size Distance from screen (mm) Diagonal Min Max Vertical length Average offset (mm) Inch W (mm) H (mm) mm (max. zoom) length (min. zoom) 30 762 610 457 1195 1253 1311 46 40 1016 813 610 1593 1670 1748 61 50 1270 1016 762 1991 2088 2184 76 60 1524 1219 914 2390 2505 2621 91 80 2032 1626 1219 3186 3341 3495 122 100 2540 2032 1524 3983 4176 4369 152 120 3048 2438 1829 4779 5011 5243 183 150 3810 3048 2286 5947 6264 6553 229 200 5080 4064 3048 7965 8352 8738 305 250 6350 5080 3810 9957 10439 10922 381 300 7620 6096 4572 11948 12527 13106 457 Connection When connecting a signal source to the projector, be sure to: 1.

With the advent of digital signal processing, digital display devices like this projector can dynamically stretch and scale the image output to a different aspect than that of the image input signal. To change the projected picture ratio (no matter what aspect the source is): • Using the remote control 1. Press Aspect to show the current setting. 2. Press Aspect repeatedly to select an aspect ratio to suit the format of the video signal and your display requirements. • Using the OSD menu 1. Press MENU/EXIT and then press / until the DISPLAY menu is highlighted. 2. Press to highlight Aspect Ratio. 3. Press / to select an aspect ratio to suit the format of the video signal and your display requirements.

About the aspect ratio • In the pictures below, the black portions are inactive areas and the white portions are active areas. • OSD menus can be displayed on those unused black areas.

1. Auto: Scales an image proportionally to fit the projector's native resolution in its horizontal or vertical width. This is suitable for the incoming image which is neither in 4:3 nor 16:9 and you want to make most use of the screen without altering the image's aspect ratio. 2. Real: The image is projected as its original resolution, and resized to fit within the display area. For input signals with lower resolutions, the projected image will display smaller than if resized to full screen. You could adjust the zoom setting or move the projector towards the screen to increase the image size if necessary. You may also need to refocus the projector after making these adjustments. 3. 4:3: Scales an image so that it is displayed in the center of the screen with a 4:3 aspect ratio. This is most suitable for 4:3 images like some computer monitors, standard definition TV and 4:3 aspect DVD movies, as it displays them without aspect alteration. 4. 16:9: Scales an image so that it is displayed in the center of the screen with a 16:9 aspect ratio. This is most suitable for images which are already in a 16:9 aspect, like high definition TV, as it displays them without aspect alteration. 5. 16:10: Scales an image so that it is displayed in the center of the screen with a 16:10 aspect ratio. This is most suitable for images which are already in a 16:10 aspect, as it displays them without aspect alteration. 15:9 picture 4:3 picture 16:9 picture 4:3 picture 16:9 picture 16:10 picture Operation 25

Operation 26Optimizing the image Using Wall Color In the situation where you are projecting onto a colored 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. To use this function, go to the DISPLAY > Wall Color menu and press / to select a color which is closest to the color of the projection surface. There are several precalibrated colors to choose from: Light Yellow, Pink, Light Green, Blue, and Blackboard.

Based on your needs, you can make adjustments to these functions by highlighting them and pressing / on the projector or remote control. Adjusting Brightness The higher the value, the brighter the image. And the lower the setting, the darker 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. Adjusting 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. Adjusting 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. 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. 1. Cool: Makes images appear bluish white. 2. Normal: Maintains normal colorings for white. 3. Warm: Makes images appear reddish white. *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. +30 +50 +70 0 -30 +30 Operation 27

Press MENU/EXIT to exit and save the settings 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. Go to the PICTURE menu and highlight 3D Color Management. 2. Press MODE/ENTER on the projector or remote control and the 3D Color Management page appears. 3. Highlight Primary Color and press / to select a color from among Red, Yellow, Green, Cyan, Blue, or Magenta. 4. Press to highlight Hue and press / to select its range. Increase in the range will include colors consisted of more proportions of its two adjacent colors. Operation 28 Please refer to the illustration to the right 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. 5. Press to highlight Saturation and adjust its values to your preference by pressing / . 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. 6. Press to highlight Gain and adjust its values to your preference by pressing / . The contrast level of the primary color you select will be affected. Every adjustment made will reflect to the image immediately. 7. Repeat steps 3 to 6 for other color adjustments. 8. Make sure you have made all of the desired adjustments. 9.
