    							Positioning your projector 15
    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.
    The maximum (native) resolution of the projector is 1024 x 768 pixels, which is a 4 to 3 
    aspect ratio (expressed as 4:3). To be able to project a complete 16:9 (widescreen) aspect 
    ratio image, the projector can resize and scale a widescreen image to the projectors native 
    aspect width. This will result in a proportionally smaller height equivalent to 75% of the 
    projectors native aspect height.
    Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image displayed 
    by this projector. This will be seen as darkened (unlit) bars along the top and bottom 
    (vertical 12.5% height respectively) of the 4:3 projection display area whenever displaying a 
    scaled 16:9 aspect image in the vertical centre of the 4:3 projection display area.
    When determining the position of your projector, you should consider its intended use and 
    input signal aspect ratios. All inputs (other than composite Video being fed a 16:9 aspect 
    signal) will display in a 4:3 aspect ratio (and will require an additional 33% display height 
    than that of the scaled 16:9 aspect image projection area).
    IMPORTANT: Do not select a permanent projector position based upon a 16:9 projection if you 
    will ever need to select an input (other than composite Video being fed a 16:9 aspect signal).
    The projector should always be placed horizontally level (like flat on a table), and positioned 
    directly perpendicular (90° right-angle square) to the horizontal centre of the screen. This 
    prevents image distortion caused by angled projections (or projecting onto angled surfaces). 
    The modern digital projector does not project directly forward (like older style reel-to-reel 
    film projectors did). Instead, digital projectors are designed to project at a slightly upward 
    angle above the horizontal plane of the projector. This is so that they can be readily placed 
    on a table and will project forward and upwards onto a screen positioned so that the bottom 
    edge of the screen is above the level of the table (and everyone in the room can see the 
    screen). 
    If the projector is mounted on a ceiling, it must be mounted upside-down so that it projects 
    at a slightly downward angle. 
    You can see from the diagram on page 17, that this type of projection causes the bottom edge 
    of the projected image to be vertically offset from the horizontal plane of the projector. 
    When ceiling mounted, this refers to the top edge of the projected image.
    If the projector is positioned further away from the screen, the projected image size 
    increases, and the vertical offset also increases proportionately.      
    When determining the position of the screen and projector, you will need to account for 
    both the projected image size and the vertical offset dimension, which are directly 
    proportional to the projection distance.
    BenQ has provided a table of 4:3-aspect-ratio screen sizes to assist you in determining the 
    ideal location for your projector. There are two dimensions to consider, the perpendicular 
    horizontal distance from the centre of the screen (projection distance), and the vertical 
    offset height of the projector from the horizontal edge of the screen (offset).4:3 aspect image in a 4:3 aspect display area16:9 aspect image scaled to a 4:3 aspect dis-

    How to determine the position of the projector for a given 
    screen size:
    1. Select your screen size.
    2. Refer to the table and find the closest match to your screen size in the left columns 
    labelled Screen Diameter Using this value, look across this row to the right to find the 
    corresponding average distance from screen value in the column labelled Average. 
    This is the projection distance.
    3. On that same row, look across to the right column and make note of the vertical Offset 
    value. This will determine the final vertical offset placement of the projector in 
    relation to the edge of the screen.
    4. The recommended position for the projector is aligned perpendicular to the 
    horizontal centre of the screen, at the distance from the screen determined in step 2 
    above, and offset by the value determined in step 3 above.
    For example, if you are using a 120 inch screen, the average projection distance is 4691 mm 
    and with a vertical offset of 46 mm.
    If you place the projector in a different position (to that recommended), you will have to tilt 
    it down or up to center the image on the screen. In these situations, some image distortion 
    will occur. Use the Keystone function to correct the distortion. See Correcting keystone on 
    page 28 for keystone correction.
    How to determine the recommended screen size for a 
    given distance:
    This method can be used for situations where you have purchased this projector and would 
    like to know what screen size will fit in your room.
    The maximum screen size is limited by the physical space available in your room. 
    1. Measure the distance between the projector and where you want to position the 
    screen. This is the projection distance.
    2. Refer to the table and find the closest match to your measurement in the average 
    distance from screen column labelled Average. Check that your measured distance is 
    between the min and max distances listed on either side of the average distance value.
    3. Using this value, look across that row to the left to find the corresponding screen 
    diameter listed in that row. That is the projected image size of the projector at that 
    projection distance.
    4. On that same row, look across to the right column and make note of the vertical Offset 
    value. This will determine the final placement of the screen in relation to the 
    horizontal plane of the projector. 
    For example, if your measured projection distance was 4.5m (4500mm), the closest match in 
    the Average column is 4617mm. Looking across this row shows that a 3000mm (3m) screen 
    is required. If you can only obtain imperial sized screens, the listed screen sizes on either side 
    of the 3m screen are the 9 and 10 screens. 
    Checking the min and max projection distance values for these screen sizes, indicates that 
    the 4.5m measured projection distance will fit these screens too. The projector can be 
    adjusted (using the zoom control) to display on these different screen sizes at that projection 
    distance. Be aware that these different screens have different vertical offset values.

    Connection
    When connecting a signal source to the projector, be sure to:
    1. Turn all equipment off before making any connections.
    2. Use the correct signal cables for each source.
    3. Ensure the cables are firmly inserted. 
    In the connections shown below, some cables may not be included with the 
    projector (see Shipping contents on page 6). They are commercially available 
    from electronics stores.
    Wireless connection (optional)
    The Wireless module allows for simultaneous wireless connectivity to multiple computers 
    which are Wi-Fi enabled. This saves you from having to swap data cables between the 
    projector and different computers during a presentation. Wi-Fi connectivity is most suitable 
    for situations where multiple presenters with separate notebooks are required to seamlessly 
    present individual presentations, like in meetings, conferences, lectures and, classrooms. 
    The Wireless module connects and attaches to the rear of the projector through the DVI-I 
    socket.
    Whilst the Wireless module is attached to the projector, you cannot use the DVI-I socket for 
    DVI cable connections.
    Even though the projector may be using a wireless data connection, it still requires physical 
    connection to a power outlet using its power cable.
    You can purchase a BenQ wireless module from 
    BenQ retailers. You should attach the wireless 
    module to the projector before you connect any 
    other cables. Refer to the user’s manual 
    enclosed with the wireless module for 
    connection and operation details.

    Connecting Video source devices
    This section describes how to connect the projector to Video source devices using video 
    cables. Video cable connections are recommended for Video presentations. 
    This projector also supports data (graphic) PC connection using Wi-Fi. Wi-Fi connection is 
    not recommended for Video presentations. See Wireless connection (optional) on page 18.
    You can connect your projector to various Video source devices that provide any one of the 
    following output sockets:
    • Component Video
    •S-Video
    •Video (composite)
    You need only connect the projector to a Video source device using just one of the above 
    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:
    Best video quality
    The best available video connection method is Component Video (not to be confused with 
    composite Video). Digital TV tuner and DVD players output Component Video natively, so 
    if available on your devices, this should be your connection method of choice in preference 
    to (composite) Video.
    See Connecting a Component Video source device on page 22 for how to connect the 
    projector to a component video device.
    Better video quality
    The S-Video method provides a better quality analog video than standard composite Video. 
    If you have both composite Video and S-Video output terminals on your Video source 
    device, you should elect to use the S-Video option.
    See Connecting an S-Video source device on page 23 for how to connect the projector to 
    an S-Video device.
    Least video quality
    Composite Video is an analog video and will result in a perfectly acceptable, but less than 
    optimal result from your projector, being the least video quality of the available methods 
    described here.
    See Connecting a composite Video source device on page 24 for how to connect the 
    projector to a composite Video device.
    Connecting Audio
    The projector has a 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 theatre or 
    home cinema applications. Any stereo audio input (if provided), is mixed into a common 
    mono audio output through the projector speaker.
    If you wish, 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. The 
    audio output is a mixed mono signal and controlled by the projector Volume and Mute 
    settings.
    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.
