Introduction 15

Remote control effective range

Infra-Red (IR) remote control sensors are located on the front and the back of the projector. The remote control must be held at an angle within 30 degrees perpendicular to the projector's IR remote control sensors to function correctly. The distance between the remote control and the sensors should not exceed 6 meters (~ 20 feet).

Make sure that there are no obstacles between the remote control and the IR sensors on the projector that might obstruct the infra-red beam.

• Operating the projector from the front

• Operating the projector from the rear

Remote control batteries

1. To open the battery cover, turn the remote control over to view its back, push on the finger grip on the cover and slide it up in the direction of the arrow as illustrated. The cover will slide off.

2. Remove any existing batteries (if necessary) and install two AAA batteries observing the battery polarities as indicated in the base of the battery compartment. Positive (+) goes to positive and negative (-) goes to negative.

3. Refit the cover by aligning it with the base and sliding it back down into position. Stop when it clicks into place.

• Avoid leaving the remote control and batteries in an excessive heat or humid environment

like the kitchen, bathroom, sauna, sunroom or in a closed car.

• Replace only with the same or equivalent type recommended by the battery manufacturer.

• Dispose of the used batteries according to the manufacturer's instructions and local

environment regulations for your region.

• Never throw the batteries into a fire. There may be danger of an explosion.

• If the batteries are dead or if you will not be using the remote control for an extended

period of time, remove the batteries to avoid damage to the remote control from possible battery leakage.

Introduction16

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.

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 Rear Table in the System Setup: Basic > Projector Position menu after you turn the projector on.

4. Rear Ceiling Select this location with the projector suspended

Note that a special rear projection screen and the BenQ Projector Ceiling Mounting Kit are required for this installation location.

Set Rear Ceiling in the System Setup: Basic > Projector Position 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 projector 17

If you use the projector with wireless function, there's no need to worry about data cable connections.This gives you the flexibility to site the projector anywhere in the room up to a range of 20m away from your notebook, and switch between presentations on different notebooks instantly without fiddling with cables

To use the wireless function, you need to install a BenQ wireless module to the projector and enable your notebook/desktop PC with wireless connection. For more information, refer to

"Wireless connection (optional)" on page 22.

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 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.

Positioning your projector18

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 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 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 21, 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 projector 19

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 Diagonal'. 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 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 4432 mm and with a vertical offset of 302 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 35 for details.

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 diagonal 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 4.8m (4800mm), the closest match in the Average column is 5089 mm. Looking across this row shows that a 3500 mm (3.5 m) screen is required. If you can only obtain imperial sized screens, the listed screen sizes on either side of the 3.5 m screen are the 10' and 12' screens.

Checking the min and max projection distance values for these screen sizes, indicates that the 4.8 m measured projection distance will need to be reduced to fit the 10' size screen, or increased to fit the 12' 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 optical characteristics. This will help you determine the exact mounting position so that it best suits your installation location.

Positioning your projector 21

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 10). 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.

The Wireless module connects and attaches to the rear of the projector through the DVI-I socket.

While 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 wireless function. Wireless connection is not recommended for Video presentations. See "Wireless connection

(optional)" on page 22.

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 best available video connection method is DVI. If your source device is equipped with a DVI socket, based on the type of DVI connector you have, you can enjoy digital or high-end analog video quality.

See "Connecting a DVI source device" on page 26 for how to connect the projector to a DVI source device and other details.

If no DVI source is available, the next best video signal is Component Video (not to be confused with composite Video). Digital 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 27 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 29 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 30 for how to connect the projector to a composite Video device.

Connection 25

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.

The audio connections illustrated 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 DVI source device

The projector provides a DVI-I input socket that allows you to connect it to a DVI source device like a DVD player, or a VGA output device like a notebook or desktop computer.

There are three types of DVI connectors: DVI-A, DVI-D, and DVI-I. The DVI-I socket is an integrated connector which supports both formats: DVI-A, and DVI-D.

DVI-A format is used to carry a DVI signal to an analog (VGA) display, or vice-versa. Although some signal quality is lost from the signal conversion, it still transmits higher picture quality than a standard VGA connection.

DVI-D format is used to directly carry a digital signal to a digital display without signal conversion. The pure digital connection provides faster and higher image quality than an analog connection, due to the nature of the digital format.

DVI-A and DVI-D formats are non-interchangeable. You cannot connect a DVI-A format connector to DVI-D equipment and visa-versa. Make sure you know which kind of format your equipment is fitted with before you purchase any cables. Or you can purchase a DVI-I cable which will be more useful in any type of DVI connection situation.

Examine your source device to determine if it has an unused DVI or VGA (D-Sub) output socket 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.

Connection26

To connect the projector to a DVI source device or a computer:

For information on connecting a DVI source device to a computer through a VGA to DVI-A cable, see "Connecting a computer" on page 22.

1. Take the DVI (DVI-D or DVI-I) cable and connect one end to the DVI output socket of the DVI source device.

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

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

4. If you wish, you can use another suitable audio cable and connect one end of the cable to the AUDIO OUT socket of the projector, and the other end to your external speakers (not supplied). The audio output is a mixed mono signal. Once connected, the audio can be controlled by the remote control (MUTE) or projector On-Screen Display (OSD) menus. See "Audio Settings" on page 50 for details.

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 aspect the source is) by pressing ASPECT on the remote control or in the DISPLAY > Aspect Ratio menu. Select an aspect ratio to suit the format of the video signal and your display requirements. There are four aspect ratios available:

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

1. Auto: Scales an image proportionally to fit the projector's native

resolution in its horizontal width. This is suitable for the incoming image which is either in 4:3 nor 16:9 and you want to make most use of the screen without altering the image ratio.

2. Actual Size: The image is projected as its original resolution, with no

pixel conversion. 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 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.

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 27 and "Obtaining a preferred projected image size" on page 19 for details.

Lamp information

Calculation of lamp hour

When the projector is in operation, the duration (in hours) of lamp usage is automatically calculated by the built-in timer. The method of calculating the equivalent lamp hour is as follows:

Total (equivalent) lamp hour

= 3/4 (hours used in Economic mode) +1 (hours used in normal mode)

See "Lamp Mode (Normal)" on page 51 for more information on Economic mode.

The lamp hour in Economic mode is calculated as 3/4 of that in normal mode. That is, using the projector in Economic mode helps to extend the lamp hour by 1/3.

Warning message

When the Lamp indicator lights up red or a message appears suggesting it is time to replace the lamp, please install a new lamp or consult your dealer. An old lamp may cause a malfunction in the projector and in some instances the lamp may explode.

The Lamp indicator light and Temperature warning light will light up if the lamp becomes too hot. Turn the power off and let the projector cool for 45 minutes. If the Lamp or Temp indicator still lights up after turning the power back on, please contact your dealer. See

"Indicators" on page 60 for details.

The following Lamp warning displays will remind you to change the lamp.
