Positioning your projector

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 the possible installation locations:

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.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.

3.Rear Ceiling

Select this location with the projector suspended upsidedown from the ceiling behind the screen.

Note that a special rear projection screen and qualified 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.Front Ceiling

Select this location with the projector suspended upsidedown from the ceiling in front of the screen.

Purchase a qualified 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.

For ceiling mounting, you need the ceiling mount kit designed for this projector. Ask a specialist for installation.For details, consult your dealer.

•The warranty on this projector does not cover any damage caused by use of any non-recommended ceiling mount kit or installation of the ceiling mount kit in an improper location.

•When the projector is mounted on the ceiling, images may appear darker than those projected in the case of tabletop mounting. This isn’t a product malfunction.

• Be sure to use this projector at an altitude of less than 1500 meters.

•Installation must be done by a qualified professional.

When the projector is installed on the ceiling using the ceiling mount kit, it is recommended to hold the mount kit and the projector using metal bars or wires in addition to the mount kit fixing screws to prevent the projector from falling due to an earthquake or other cause. For that purpose, use metal bars, wires, or screws that bear a load of at least 70 kgf. When using metal wires, secure one end to a screw hole marked with an arrow on the rear terminal panel and the other end to the mount kit. (Do not use screw holes without arrow marks.) In this case, make sure that the screws are inserted in the projector at least 5 mm. The length of the screws should be 20 mm or shorter. Also make sure that no electrical current is flowing in the mount kit due to current leakage or other cause.

ENGLISH

EN-11

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.

4:3 is the native aspect ratio of EX321U/EX241U. 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 16:9 aspect image scaled to 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.

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).

You can see from the diagram on page 14, that this type of projection causes the bottom edge of the projected image to be vertically offset from the horizontal plane of the projector.

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.

When fine streaks are seen on projected images

This is due to interference with the screen surface and is not a mal-function. Replace the screen or displace the focus a little.

EN-12

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

1.Determine the aspect ratio of your screen, 16:9 or 4:3. If you have a 4:3 screen, refer to the table labeled "(Standard)". If you have a 16:9 screen, refer to the table labeled "(16:9)".

2.Select your image size.

3.Refer to the table and find the closest match to your image size in the left columns labeled "Image size". Using this value, look across this row to the right to find the corresponding average distance from screen value in the column labeled "Distance from the screen: L". This is the projection distance.

4.On that same row, look across to the right column and make note of the "Hd" value. This will determine the final vertical offset placement of the projector in relation to the edge of the image.

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.

<Example>

EX321U: If you are using a 4:3 aspect ratio, 100-inch screen, distance from the screen is 3.1 m and with a vertical offset of 11 cm at Zoom position wide.

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 26 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 "(Standard)" or "(16:9)", and find the closest match to your measurement in the distance from the Image size column. 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 "Image size". 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 "Hd" value. This will determine the final placement of the screen in relation to the horizontal plane of the projector.

<Example>

EX321U: If your measured projection distance was 3.5 m and your screen aspect ratio is 4:3, the closest match in the "Distance from the screen: L" column is from 3.1 m to 4.0 m. Looking across this row shows that a 100-inch screen is required.

The above figures are approximate and may be slightly different from the actual measurements. Mitsubishi recommends that if you intend to permanently install the projector, you should physically test the projection size and distance using the actual projector in suit 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.

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.

• See the owner’s guide of each device for details about its connections.

•Contact your dealer for details about its connections.

•In the connections shown below, some cables may not be included with the projector. They are commercially available from electronics stores.

Connecting a computer or monitor

Connecting a computer

The projector provides a RGB input socket that allows you to connect it to both IBM® compatibles and Macintosh® computers. A Mac adapter is needed if you are connecting legacy version Macintosh computers.

To connect the projector to a notebook or desktop computer:

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

2.Connect the other end of the RGB cable to the COMPUTER-1 or COMPUTER-2 signal input socket of the projector.

3.If you wish to make use of the projector speaker in your presentations, take a suitable audio cable and connect one end of the cable to the audio output jack of the computer, and the other end to the AUDIO IN jack 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 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 "Adjusting the sound" on page 32 for details.

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

Notebook or desktop computer	Audio cable (option)	Speakers
	RGB cable
	or

Audio cable (option)

Many notebooks 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 notebook. Press FN and the labeled function key simultaneously. Refer to your notebook's documentation to find your notebook's key combination.

•When you use a longer RGB cable instead of the provided cable, the image may not be projected correctly.

•Some computers require additional connectors or analog RGB output adapters to be connected with this projector.

EN-16

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 MONITOR OUT signal output jack on the projector to an external monitor following the instructions below:

To connect the projector to a monitor:

1.Connect the projector to a computer as described in "Connecting a computer" on page 16.

2.Connect the RGB cable from the monitor to the MONITOR OUT jack of the projector.

Notebook or desktop computer

ENGLISH

RGB cable

• Once the Standby Monitor Out function is on, the projector can output a VGA signal when it is in standby mode and an appropriate D-Sub input is made to the COMPUTER-1 jack.

•Images may not be displayed correctly depending on the type of the input signal. See the instruction manual of the monitor.

•Images may not be displayed correctly depending on the type of the cable.

Connecting Video source devices

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

•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:

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 experience. See "Connecting an HDMI device" on page 18" for how to connect the projector to an HDMI device.

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 18 for how to connect the projector to a component video device.

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 19 for how to connect the projector to an S- Video device.

If you have only composite Video output terminals on your Video source device, connect to Composite Video input. See "Connecting a composite Video source device" on page 20 for how to connect the projector to a composite Video device.

EN-17

Connecting an HDMI device

You should use an HDMI cable when making connection between the projector and HDMI devices.

To connect the projector to an HDMI device:

1.Take an HDMI cable and connect one end to the HDMI output port of the video device.

2.Connect the other end of the cable to the HDMI input port on the projector.

AV device

HDMI cable (option)

In the unlikely event that you connect the projector to a DVD player via the projector's HDMI input and the projected picture displays wrong colors, please change the color space to YUV. See "Changing Color Space" on page 24 for details.

When you connect this projector and a Digital device (such as a DVD player) via the HDMI terminal, black color may appear dark and deep, depending on the type of the connected device.

•This depends on the black level setting of the connected device. There are two kinds of methods to digitally transfer image data, in which different black level settings are employed respectively. Therefore, the specifications of the signals output from DVD players differ, depending on the type of the digital data transfer method they use.

•Some DVD players are provided with a function to switch the methods to output digital signals. When your DVD player is provided with such function, set it as follows.

EXPAND or ENHANCED -> NORMAL

•See the users guide of your DVD player for details.

•When you switch to HDMI input, the projected picture may display wrong colors for about 1 second. This is not product malfunction.

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:

1.Take a Component Video to RGB (D-Sub) adaptor cable and connect the end with 3 RCA type connectors to the Component Video output sockets of the Video source device. Match the color of the plugs to the color of the sockets; green to green, blue to blue, and red to red.

2.Connect the other end of the Component Video to RGB (D-Sub) adaptor cable (with a D-Sub type connector) to the COMPUTER-1 or COMPUTER-2 socket on the projector.

3.If you wish to make use of the projector speaker in your presentations, take a suitable audio cable and connect one end of the cable to the audio output jack of the computer, and the other end to the AUDIO IN jack 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 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 "Adjusting the sound" on page 32 for details.
