Positioning the projector

To determine where to position the projector, consider the size and shape of your screen, the location of your power outlets, and the distance between the projector and the rest of your equipment. Here are some guidelines:

•Position the projector on a flat surface at a right angle to the screen. The projector must be at least 4.9 feet (1.5m) from the projection screen.

•For safety reasons, position the projector within 10 feet (3m) of your power source (running extension cables may introduce a trip hazard). To ensure adequate cable access, do not place the projector within 6 inches (.15m) of a wall or other object.

•If you are installing the projector on the ceiling, refer to the installation guide that comes with the Ceiling Mount Kit for more information. To turn the image upside down, see “Ceiling” on page 26. We recommend using an InFocus authorized ceiling mount.

•Position the projector the desired distance from the screen. The distance from the lens of the projector to the screen, the zoom setting, and the video format determine the size of the projected image.

•The image offset is 128% for the IN72. This means that if you have an image 10’ high, the bottom of the image will be 2.8’ above the center of the lens. For the IN74 and IN76, the image offset is 115%.

Choosing the aspect ratio

Aspect ratio is the ratio of the image width to image height. HDTV and most DVDs are 16:9, which is the default for this projector. When in 4:3 mode the projector places black bars on both sides of the image. Native mode centers the image and turns off the internal scaler so that any resolution larger than the native projector resolution is cropped on the edges. Letterbox expands the image to fill the screen.

What you plan to project will also help you choose between 4:3 and 16:9. For example, most TV shows are 4:3, while most movies are 16:9. If you have a 16:9 screen, then you should select an aspect ratio of 16:9 for anamorphic movies and HDTV, and Native for 4:3 content. If you have a 4:3 screen you should still use 16:9 for anamorphic movies or HDTV, but you also have the option of using 4:3, Native, or Natural Wide for 4:3 content. Keep in mind that anamorphic movies only appear correctly if the DVD player is set to output to a 16:9 television. Natural Wide stretches a 4:3 image to fill the entire 16:9 screen. The center two-thirds of the image is unchanged; the edges of the image are stretched.

Video connectors

The first step for connecting video is determining what type of output connectors your video device has. If there is more than one output, select the one with the highest quality. The best quality ranking, with 1 being the highest, is:

1M1-DA/DVI or HDMI (both are digital inputs)

2component /SCART RGB video (RCAs)

3S-video

4composite video (RCA)

If your device has a VGA connector, you can use the M1-DA/DVI connector for a high quality image. Many PC game systems have VGA connectors.

Connecting a video device

You can connect video devices such as VCRs, DVD players, camcorders, digital cameras, video game consoles, HDTV receivers, and TV tuners to the projector. Connect the audio from your video device to your stereo system to get sound.

You can connect the projector to most video devices that can output video. You cannot directly connect the coaxial cable that enters your house from a cable or satellite company, the signal must pass through a tuner first. Examples of tuners are digital cable boxes, VCRs, digital video recorders, and satellite TV boxes. Basically, any device that can change channels is considered a tuner.

A composite video cable is provided with your projector so you can quickly and easily connect a video source to the projector and see the amazing image that is displayed. Once you have determined a more permanent location for your projector, we recommend purchasing higher quality cables in the proper length to get the best image from your particular video equipment. High quality cables optimized for your projector can be purchased from www.infocus.com/store (in select areas) or from your dealer or retailer.

Composite (RCA) video connection

Plug the composite video cable’s yellow connector into the video-out connector on the video device. Plug the other yellow connector into the yellow Composite connector on the projector.

S-video connection

If your video device uses a round, four-prong S-video connector, plug the S-video cable into the S-video connector on your video device and into the S-video connector on the projector.

Component (RCA) connection

If your device uses component connectors, plug a component video cable with red, green, and blue RCA connectors into the source device’s component connectors and the Component connectors on the projector.

SCART RGB connection

SCART (from Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) is a French-originated standard and connector for connecting audio and video equipment to display devices. The video signal is separated into its primary components for brighter, more accurate colors and sharper detail. You must enable this connector in the Source Enable menu to use it, see page 26. You will also need a SCART to 4-RCA adapter to connect to your SCART device.

8

Digital connections

The M1-DA/DVI and HDMI (High-Definition Multimedia Interface) connectors are digital and yield the highest quality image. It is common for these signals to be encrypted with HDCP (high-bandwidth digital-content protection). Your new projector ships standard with decryption codes so you can enjoy these high quality, all digital images.

This projector uses the M1-DA connector, which has the following advantages:

•allows connection to a digital DVI source

•allows connection to a component source

•allows connection to an analog computer source

•carries a USB control signal which allows you to easily update your projector’s software as enhancements become available.

•has output pins that can power accessories.

The IN76 is an HDTV (High Definition Television) monitor, meaning it has vertical scanning lines of 720 progressive, 1080 interlaced or higher. The IN72 and IN74 are EDTV (Enhanced Definition Television) monitors, meaning they have vertical scanning lines of 480 progressive or higher. HD content can be displayed on an EDTV monitor, the resolution is just less than that of an HDTV.

DVI connection

If your video device uses a DVI connector, plug the DVI end of an M1-DA cable into the video-out connector on the video device. This connector may be labeled “To Monitor” on the video device. Plug the M1-DA end of the cable into the M1-DA/DVI connector on the projector.

HDMI connection

HDMI is a standard, uncompressed, all-digital audio/video interface. HDMI provides an interface between sources, such as set-top boxes, DVD players, and receivers and your projector. Plug an HDMI cable into the video-out connector on the video device and into the HDMI connector on the projector.

Note that the projector has no audio capabilities, so audio signals transferred through HDMI will not be audible.

Computer connections

You can connect a computer’s VGA connector to the M1-DA/DVI input on the projector using an M1-A cable.

RS-232 connections (IN74 and IN76 only)

You can control the projector from an LCD control panel or computer by connecting an RS-232 cable to the projector’s Serial control connector. Specific RS-232 commands can be found in the Service section of our website at www.infocus.com/support.
