Choosing a location

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.
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 a 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 Mounting Kit from
your dealer to mount your projector on the ceiling. Set Front Ceiling in the SYSTEM SETUP: Basic >
Projector Position menu after you turn the projector on.
3. Rear Table Select this location with the projector placed on a table
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 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 Rear Ceiling in the SYSTEM SETUP: Basic > Projector Position menu after you turn the projector on.
Positioning your projector14

Obtaining a preferred projected image size

The distance from the projector lens to the screen, the zoom setting (if available), and the video format each factors in the projected image size.
16:9 is the native aspect ratio. SP840 can project a complete 16:9 (widescreen) image.
English
4:3 aspect image in a 16:9
aspect display area
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 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 screen sizes to assist you in determining the ideal location for your projector. Refer to "SP840 projection dimensions" on page 17 depending on the projector you are using. 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 15
English

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 "16:9 screen". 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 in mm" 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 4646 mm and with a vertical offset of 448 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 31 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". If the min and max values are available on the table, 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 in mm" 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 4.0 m (4000mm), the closest match in the "Average" column is 3872 mm. Looking across this row shows that a 100-inch screen is required.

There is 5% 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 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.

Connecting Video source devices

You can connect your projector to various Video source devices that provide any one of the following output jacks:
•HDMI
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 HDMI. If your source device is equipped with a HDMI jack, you can enjoy uncompressed digital video quality.
See "Connecting HDMI source devices" on page 21 for how to connect the projector to a HDMI source device and other details.
If no HDMI 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 Component Video source devices" 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.
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 S-Video source devices" on page 23 and "Connecting Composite Video
source devices" on page 24 for how to connect the projector to an S-Video or 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. They are not designed for, nor intended for stereo audio reproduction use as might be expected in home theater or home cinema applications. Any stereo audio input (if provided), is mixed into a common mono audio output through the projector speakers.

Connecting HDMI source devices

HDMIHDMI
AV device
HDMI cable
The projector provides a HDMI input jack that allows you to connect it to a HDMI source device like a DVD player, a DTV tuner or a display.
HDMI (High-Definition Multimedia Interface) supports uncompressed video data transmission between compatible devices like DTV tuners, DVD players and displays over a single cable. It provides pure digital viewing and listening experience.
Examine your Video source device to determine if it has a set of unused HDMI output jacks 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 an HDMI source device:
1. Take a HDMI cable and connect one end to the HDMI output jack of the HDMI source device. Connect the other end of the cable to the HDMI signal input jack on the projector. Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus. See "Audio Settings" on page 53 for details.
The final connection path should be like that shown in the following diagram:
English
In the unlikely event that you connect the projector to a DVD player and the projected
picture displays wrong colors, please change the color space to a suitable selection (RGB/ SDTV/HDTV). See "Changing Color Space" on page 29 for details.
If no signal is detected after establishing the connection, turn off the Quick Auto Search
function in the SOURCE menu. See "Switching input signal" on page 29 for details.

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.

Adjusting Brilliant Color
Highlight Brilliant Color in the PICTURE: Advanced menu and select by pressing
/ on the projector or remote control.
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.
On is the default and recommended selection for this projector. When Off is selected, the Color Temperature function is not available.
Selecting a White Peaking
Highlight White Peaking in the PICTURE: Advanced menu and adjust the values by pressing / on the projector or remote control.
This adjustable item utilizes a new color-processing algorithm and system level enhancements to enable higher brightness while providing true, more vibrant colors in picture. The range is from 1 to 3. If you prefer a stronger enhanced image, adjust toward the maximum setting. For a smoother, more natural image, adjust toward the minimum setting.
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 proj ector, however, you r proje c tor suppli er 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.

Maintenance

Care of the projector

Your projector needs little maintenance. The only thing you need to do on a regular basis is to keep the lens clean.
Never remove any parts of the projector except the lamp. Contact your dealer if other parts need replacing.

Cleaning the lens

Clean the lens whenever you notice dirt or dust on the surface.
Use a canister of compressed air to remove dust.
If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner and gently wipe the lens surface.
Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile solvent, such as alcohol, benzene, thinner or insecticide. Using such materials or maintaining prolonged contact with rubber or vinyl materials may result in damage to the projector surface and cabinet material.

Cleaning the projector case

Before you clean the case, turn the projector off using the proper shutdown procedure as described in "Shutting down the projector" on page 46 and unplug the power cord.
To remove dirt or dust, wipe the case with a soft, lint-free cloth.
To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH detergent. Then wipe the case.
Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case.

Lamp information

Getting to know the 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 = 1 (hours used in Economic mode) + 4/3 (hours used in normal mode)
See "Setting Lamp mode as Economic" below for more information on Economic mode.
To obtain the lamp hour information:
1. Press Menu/Exit and then press / until the SYSTEM SETUP: Advanced menu is
highlighted.
2. Press to highlight Lamp Settings and press MODE/ENTER. The Lamp Settings page
displays.
3. You will see the Equivalent lamp hour information displaying on the menu.
4. To leave the menu, press Menu/Exit.
You can also get the lamp hour information on the INFORMATION menu.

Extending lamp life

The projection lamp is a consumable item that normally can last up to 1500-2000 hours with proper usage. To keep the lamp life as long as possible, you can do the following settings via the OSD menu.
Setting Lamp mode as Economic
Using Economic mode reduces system noise and power consumption by 20%. If the Economic mode is selected, the light output will be reduced and result in darker projected pictures.
Setting the projector in Economic mode also extends the lamp operation life. To set Economic mode, go into the SYSTEM SETUP: Advanced > Lamp Settings > Lamp mode menu and press / .
Setting Auto Power Off
This function allows the projector to turn off automatically if no input source is detected after a set period of time to prevent unnecessary waste of lamp life.
To s et Auto Power Off, go into the SYSTEM SETUP: Basic > Auto Power Off menu and press / . The time period can be set from 5 to 30 minutes in 5-minute increments. If the preset time lengths are not suitable for your presentation, select Disable. The projector will not automatically shut down in a certain time period.
