⚠️ 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.

Operating the LASER pointer

The Laser Pointer is a presentation aid for professionals. It emits red colored light when you press it and the indicator lights up red.

The laser beam is visible. It is necessary to press and hold LASER for continuous output.

Avoid Exposure Laser radiation is embed from the aperture

BENQ MP782 ST - Operating the LASER pointer - 2

Do not look into the laser light window or shine the laser light beam on yourself or others. See the warning messages on the back of the remote control prior to using it.

The laser pointer is not a toy. Parents should be mindful of the dangers of laser energy and keep this remote control out of the reach of children.

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 8 meters ( 26 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.

BENQ MP782 ST - Replacing the remote control batteries - 2

- 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.

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.

BENQ MP782 ST - Front Table - 1

natural_image Simple line drawing of a pendulum setup with a pendulum, a ball on a table, and a human silhouette (no text or symbols)

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 Position 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.

Set Rear Ceiling in the SYSTEM SETUP: Basic > Projector Position menu after you turn the projector on.

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.

Set Rear Table in the SYSTEM SETUP: Basic > Projector Position menu after you turn the projector on.

BENQ MP782 ST - Rear Table - 1

natural_image Diagram showing a person observing a camera setup with a screen and pointer (no text or symbols)

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.

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 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).

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 diagrams 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 tables of 16:9-aspect-ratio and 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).

How to determine the position of the projector for a given screen size

  1. Determine the aspect ratio of your screen? Refer to page 17-19 depending on the projected picture aspect ratio you've got.
  2. Select your screen size.
  3. Find the closest match to your screen size in the left columns labelled "(a) Screen size". Using this value, look across this row to the right to find the corresponding average distance from screen value in the column labelled "(b) Distance from screen". This is the projection distance.
  4. On that same row, look across to the right column and make note of the "(c) Vertical offset" value. This will determine the final vertical offset placement of the projector in relation to the edge of the screen.
  5. 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 3 above, and offset by the value determined in step 4 above.

For example, if you are using an 120-inch, 4:3-aspect-ratio screen and the projected picture is 16:10, please refer to Table B2 on page 18, the recommended projection distance is 1192 mm and the vertical offset is 76 mm.

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 page 17-19 depending on the screen aspect ratio you need and find the closest match to your measurement in the average distance from screen column labelled "(b) Distance from screen". This is the projection distance.
  3. Using this value, look across that row to the left to find the corresponding "(a) Screen size" 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 "(c) Vertical offset" value. This will determine the final placement of the screen in relation to the horizontal plane of the projector.

For example, if you need a 16:9 screen to project a 16:9 picture and your measured projection distance is 1.5 m (1500 mm), please refer to Table A1 on page 17. The closest match in the "(b) Distance from screen" column is 1623 mm. Looking across this row shows that a 150" (about 3.8 m) screen is required.

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 30 for details.

Connecting audio

The projector has two built-in mono speakers which are 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.

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 on page 20 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-D device

You should use a DVI-D cable when making connection between the projector and DVI-D device.

To connect the projector to a DVI-D device:

  1. Take a DVI-D cable and connect one end to the DVI-D output port of the video device.
  2. Connect the other end of the cable to the DVI-D input port on the projector.
  3. If you wish to make use of the projector (mixed mono) speakers in your presentations, take a suitable audio cable and connect one end of the cable to the audio output jack of the device, and the other end to the AUDIO or AUDIO (L/R) jack of the projector.
  4. If you wish and the AUDIO OUT jack is available on your projector, you can use another suitable audio cable and connect one end of the cable to the AUDIO OUT jack of the projector, and the other end to your external speakers (not supplied). Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus. See "Audio Settings" on page 52 for details.

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.

On is the default and recommended selection for this projector. 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. T1: With the highest color temperature, T1 makes the image appear the most bluish white than other settings.
  2. T2: Makes images appear bluish white.
  3. T3: Maintains normal colorings for white.
  4. T4: 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.

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 is displayed.
  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.

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.

  1. 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.

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 and case 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 45 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.

BENQ MP782 ST - Cleaning the projector case - 1

Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case.

Storing the projector

If you need to store the projector for an extended time, please follow the instructions below:

  • Make sure the temperature and humidity of the storage area are within the recommended range for the projector. Please refer to "Specifications" on page 63 or consult your dealer about the range.
  • Retract the adjuster feet.
  • Remove the batteries from the remote control.
  • Pack the projector in its original packing or equivalent.

Transporting the projector

It is recommended that you ship the projector with its original packing or equivalent. When you carry the projector yourself, please use the original box or provided soft carry 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)

BENQ MP782 ST - Getting to know the lamp hour - 1

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 ◀/▶ to highlight the SYSTEM SETUP: Advanced menu.
  2. Press ▼ to highlight Lamp Settings and press MODE/ENTER. The Lamp Settings page is displayed.
  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 3000-4000 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 signal is detected after a set period of time to prevent unnecessary waste of lamp life.

To set 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.

Timing of replacing the lamp

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.

Accessibility Requirements for Rehabilitation Act of 1973, Section 508

BenQ's commitment to accessible products allows us to support government in making accessible technology choices BenQ's LCD monitors and projectors are compliant with Section 508 guidelines by including the assistive features as below:

  • BenQ's monitors have colored "Power" indicators. While the indicator shows green, it means that the monitor is using the full power. While the indicator shows yellow or amber, it means that the monitor is in suspend or sleep mode and is using less than 2 watts of electricity.
  • BenQ's monitors have a variety of settings of pre-programmed flicker-free timing to make the screen shown on the monitor readily accessible. The default timing setting is automatically turned on every time the monitor is powered up, and thus reduces the hassle of user intervention.

- BenQ's monitors and projectors have options for brightness and contrast adjustments that text and images could be displayed differently to meet the demands of the visually impaired. Other similar adjustments are also available by using the On-Screen Display (OSD) controls on the products.

- BenQ's monitors and projectors include user-selectable color controls, such as color temperature selections (Monitor: 5800K, 6500K and 9300K, Projector: 5500K, 6500K, 7500K and 9300K), with a wide range of contrast levels.

- BenQ's multimedia monitors and projectors usually have one or two speakers for audio performance which allow users (including hearing impaired) to interact with the computer systems connected. Speaker controls are typically located on the front-panel.

- Firmware of BenQ's monitors and projectors contain unique product information that helps computer systems to identify BenQ products and activate their Plug-and-Play function when connected.

- All BenQ's monitors and projectors are compatible with the PC99 standard. For example, connectors are color-coded to help users easily connecting products to computer systems correctly.

- Some models of BenQ's monitors and projectors contain additional USB and DVI ports for connection to more devices such as a special headphone to assist the hearing impaired.

- All BenQ monitors and projectors come with user manuals on compact discs which could be easily read by commercial software such as Adobe Reader via a connected computer system. These documents are also available on the BenQ's web site (www.BenQ.com). Other types of documents may be available upon requests.

- BenQ's customer service provides answers and assistance to all our customers through phone calls, facsimiles, e-mails, or web sites.
