the battery to prevent damage to the remote control from possible battery leakage.

Introduction 11

Positioning your projector

Choosing a location

Your projector is designed to be installed in one of four possible installation locations:

1. Table in front of screen;

2. Ceiling in front of screen;

3. Table at rear of screen;

4. Ceiling at rear of screen.

1. Front Table Select this location with the projector placed near the

floor 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 Mounting Kit from your dealer to mount your projector on the ceiling.

Set in the Advanced > Mirror menu after you turn the projector on.

3. Rear Table Select this location with the projector placed near the

floor behind the screen.

Note that a special rear projection screen is required.

Set in the Advanced > Mirror menu after you turn the projector on.

4. 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 Mounting Kit are required for this installation location.

Set in the Advanced > Mirror menu after you turn the projector on.

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.

Positioning your projector12

Safety instructions for ceiling mounting of 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 prgc61 4.23(o)4.1hevc61n.1649-g(g)-t.1(v9)h.1(c)1 s.3(r4Bc.1he)-6.29t tr4B.

Positioning your projector 13

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 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 projector's native aspect width. This will result in a proportionally smaller height equivalent to 75% of the projector's native aspect height.

4:3 aspect image in a 4:3 aspect display area

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 center 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 center 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 projec tor. 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 16, 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 center of the screen (projection distance), and the vertical offset height of the projector from the horizontal edge of the screen (offset).

Positioning your projector14

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 ' 4:3 Screen Di agonal '. Using this va lue, lo ok across thi s row to t he rig ht to fi nd the corresponding average distance from screen value in the column labelled 'Average'. This is the projection distance.

3. On that s ame row, l ook acr oss to t he rig ht colu mn and m ake not e of the vertical Off set 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 center 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 4467 mm and with a vertical offset of 183 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 ima ge distortion will occur. Use the Keystone function to correct the distortion. See "Correcting keystone" on

page 29 for details.

How to determine the recommended screen size for a given distance

This method can be use d 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 diagonal listed in that row. That is the projected image size of the projector at that projection distance.

4. On that s ame row, l ook acr oss to t he rig ht colu mn and m ake not e of the vertical Off set 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 4593 mm. Looking across this row shows that a 3000 mm (3 m) screen is required. If you can only obtain imperial sized screens, the listed screen sizes on either side of the 3 m screen are the 9' and 10' screens.

Checking the min and max projection distance values for these screen sizes, indicates that the 4.5 m measured projection distance will need to be reduced to fit the 9' size screen, or increased to fit the 10' size screen. The projector can be adjusted (using the zoom control) to display on these different screen sizes at those projection distances. Be aware that these different screens have different vertical offset values.

There is 3% 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 in situ before you permanently install it, so as to make allowance for this projector's optica l characteri stics. This will help you determine the exact mounting position so that it best suits your installa tion location.

Positioning your projector16

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 wireless enabled. This saves you from having to swap data cables between the projector and different computers during a presentation. Wireless 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.

Even though the Wireless module is not attached to the projector, everytime the projector is turned on, the status of wireless connection will display on the screen while the projector is searching for input signals during the start up procedure.

Connection 17

To connect the projector to a notebook or desktop computer (either through a VGA ca bl e or VGA to DVI -A cable):

• With a VGA cable: • With a VGA to DVI-A cable:

1. Take the supplied VGA cable and connect one end to the D-Sub output socket of the computer.

2. Connect the other end of the VGA cable to the D-SUB/COMP. IN signal input socket on the projector.

3. If you wish to make use of the projector (mixed mono) speaker, take a suitable audio cable and connect one end of the cable to the audio output socket of the computer, and the other end to the Audio socket of the projector.

The final connection path should be like that shown in the following diagram:

1. Take a VGA to DVI-A cable and connect the VGA end to the D-Sub output socket of the computer.

2. Connect the DVI end of the VGA to DVI-A cable to the DVI-I signal input socket on the projector.

Many laptops do not turn on their external video ports when connected to a projector. Usually a key combo like FN + F3 or CRT/LCD key turns the external display on/off. Locate a function key labeled CRT/LCD or a function key with a monitor symbol on the laptop. Press FN and the labeled function key simultaneously. Refer to your laptop’s documentation to find your laptop’s key combination.

Connection18

Connecting a monitor

If you want to view your presentation close-up on a monitor as well as on the screen, you can connect the RGB signal output socket on the projector to an external monitor with a VGA cable following the instructions below:

1. Connect the projector to a computer as described in "Connecting a computer" on page

17.

2. Take a suitable VGA cable (only one supplied) and connect one end of the cable to the D-Sub input socket of the video monitor.

3. Connect the other end of the cable to the D-SUB OUT socket on the projector.

The final connection path should be like that shown in the following diagram:

Connecting Video source devices

This section describes how to connect the proj ector to Video s ource device s using video cables. Video cable connections are recommended for Video presentations.

This projector also supports data (graphic) "PC" connection using wireless functi on. Wireles s connection is not recommended for Video presentations. See "Wireless connection

(optional)" on page 17.

You can connect your projector to various Video source devices that provide any one of the following output sockets:

•DVI

• 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 be st available video connection meth od is DVI. If your source de vice is equ ipped with a DVI socket, based on the type of DVI connector you have, you can enjoy dig ital or hig h-end analog video quality.

See "Connecting a Component Video source device" on page 21 for how to connect the projecto r to a DVI source de vice and othe r details.

If no DVI source is available, the next best video signal is Component Video (not to be confuse d with compo site Video). Di gital TV tuners and DVD players output Component Video natively, so if available on your devices, they should be your connection method of choice in preference to S-Video or (composite) Video.

See "Connecting a Component Video source device" on page 21 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 sp eaker 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.

Connection20

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. The audio connections il lustrated in the following sections are provided for informational purposes only. You need not connect audio to the projector if there is an alternate sound system available, or if audio is not required.

Connecting a Component Video source device

Examine your Video source device to determine if it has a set of unused Component Video output sockets available:

• If so, you can continue with this procedure.

• If not, you will need to reassess which method you can use to connect to the device.

To connect the projector to a Component Video source device through a Component Video to VGA (D-Sub) adaptor cable:

•With a Component Video to VGA (D-Sub) adaptor cable:

1. Take the (optional accessory)

Component Video to VGA (D-Sub) adaptor cable and connect the end with 3 RCA ty pe connectors to the Component Video output sockets of the Video source device. Match the color of the plugs to the color of the sockets; g reen to green, blue to blue; and red to red.

2. Connect the other end of the

Component Video to VGA (D-Sub) adaptor cable (with a D-Sub type connector) to the D-SUB/COMP IN socket on the projector.

3. If you wish to make use of the projector (mixed mono) speaker, take a suitable

audio cable and connect one end of the cable to the audio output socket of the computer, and the other end to the Audio socket of the projector.

• With a DVI c able :

1. Take a DVI cable and connect one end of the cable to the DVI output socket of the Video source device.

Selecting the aspect ratio

The 'aspect ratio' is the ratio of the image width to the image height. Most analog TV and computers are in 4:3 ratio, which is the default for this projector, and digital TV and DVDs are usually in 16:9 ratio.

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 source.

You can change the projected image ratio (no matter what aspec t the source is) by entering

Pro-Picture > Aspect Ratio. Select an aspect ratio to suit the format of the

video signal and your display requirements. There are three aspect ratios available:

In the pictures below, the black portions are inactive areas and the white portions are acti ve areas.

1. Nati ve: The image is projected at its original aspect ratio, 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.

2. 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 computer monitors, standard definition TV and 4:3 aspect DVD movies, as it displays them without aspect alteration.

3. 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.

16:9 aspect ratio is only sourced through the Component Video input when being fed an appropriate 16:9 aspect signal. See "Connecting a Component Video source

device" on page 21 and "Obtaining a preferred projected image size" on page 14 for details.

Automatically resizes the input signal pixel resolution to the native resolution

of the projector.

On: The pixel resolution of the input signal is converted to the native resolution of the projector (1024 x 768). For input signals with lower resolutions, gaps in the pixels are automatically interpolated into the image before being projected. This may distort the image clarity.

Off: If larger than the native resolution of the projector, the image is 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.

There are three options to set the image's aspect ratio depending on your input signal source.

See "Selecting the aspect ratio" on page 30 for details.

fan speed.

Operation under "High Altitude Mode" may cause a higher decibel operating noise level because of increased fan speed necessary to improve overall system cooling an d performance.

If you use this projector under other extreme conditions excluding the above, it may display auto shut-down symptoms, which is designed to protect your projector from over-heating. In cases like this, you should switch to High Altitu de mode to solve these symptoms. However, this is not to state that this projector can operate under any and all harsh or extreme conditions.

This function allows the projector to turn off automatically if no input signal is detected after a set period of time. Press Left 3/Right 4on the projector or remote control to set the duration before the projector is turned off.

Use this mode to reduce system noise and reduce power consumption by 20%. If this mode is activated, the light output will be reduced and result in darker projected images.

Setting the projector in Economic mode extends the lamp timer automatic shutdown feature. For more information on how the total lamp hour is calculated, see "Calculation of lamp hour" on page 47.
