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. There is also an audio input via the red and white
A/V connectors.
You can connect the audio directly to the projector to get sound from the built-in speaker, or you can
connect the audio to your stereo system via the Audio Out connector.
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.
Before connecting your projector, you should decide which aspect ratio you want to use. The projector’s
Aspect Ratio setting is accessed through the projector’s Picture Menu. See page 22 for more information.
What is 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. This projector is not intended for use with 4:3 screens. 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
854x480 is cropped on the
edges.
If you are projecting onto a
screen, the size/shape of the
screen may determine which
aspect ratio to use. If you are
projecting onto a blank wall, you
don’t have the screen size
restriction. 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 either 4:3 or Native 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.
Video device connections
Composite (RCA) video connection
Plug the provided composite A/V cable’s yellow
connector into the video out connector on the video
device. Plug the other yellow connector into the
yellow Video 2 connector on the projector.
12 Plug a white connector into the left audio out connector on the video device and plug a red connector into the right audio out connector on the video device. Plug the remaining white connector into the white audio in connector on the projector, and plug the remaining red connector into the red audio in connector on the projector. Keep in mind that video output from composite connections are not as high quality as S-video or component video. S-video connection If your video device uses a round, seven-prong S-video connector, plug an S-video cable into the S-video connector on your video device and into the S-video connector on the projector. Use the A/V cable’s red and white audio connectors as described directly above (the yellow connectors on the A/V cable are not used). Keep in mind that S-video delivers higher-quality video output than composite, but not as high as component video. Component (RCA) connection To connect a progressive scan DVD or HD source, use the component connector. Connect a component video cable with red, green, and blue RCA connectors into the source device component connector. Connect the other three ends of the component cable into the component Video connector on the projector. Use the composite A/V cable’s red and white audio connectors as described on the previous page (the yellow connectors on the A/V cable are not used). Keep in mind that component video delivers higher quality video output than S-video or composite video. DVI connection If your video device uses a DVI connector, plug the DVI end of the M1-DA cable into the video-out connector on the video device. This connector may be labeled “To Monitor” on the video source. Plug the M1 computer end of the cable into the Computer In connector on the projector. Do not plug the USB end of this cable into the video device. Use the composite A/V cable’s red and white audio connectors as described on the previous page (the yellow connectors on the A/V cable are not used). Keep in mind that DVI video delivers the highest quality video output. Connect the power cord to the Power connector on the side of the projector and to your electrical outlet. NOTE: Always use the power cord that shipped with the projector.
13 Displaying video Remove the lens cap. Toggle the Power switch on the side of the projector to the On position. The LED flashes green and the fans start to run. When the lamp comes on, the start-up screen is displayed and the LED is steady green. It can take a minute for the image to achieve full brightness. ? No start up screen? Get help on page 15. Plug in and turn on your video device. The video device’s image should appear on the projection screen. If it doesn’t, press the Video button on the keypad. ? No image? Try pressing the Source or Auto Image Get help on page 15. Adjusting the image Adjust the height of the projector by pressing the release button to extend the foot. Rotate the leveling foot at the rear of the projector, if necessary. Position the projector the desired distance from the screen at a 90-degree angle to the screen. See page 27 for a table listing screen sizes and distances to the screen. Adjust the zoom and focus. If the image is not square, adjust the keystone using the buttons on the keypad. Press the top Keystone button to reduce the upper part of the image, and press the bottom Keystone button to reduce the lower part. Adjust the volume on the keypad or remote.
14 Adjust the Contrast, Brightness, Color, Tint, or Aspect Ratio in the Picture menu. See page 22 for help with the menus and these adjustments. For Aspect Ratio, keep in mind that DVD players must be configured for 16:9 in order to view the highest quality image. For more information regarding Aspect Ratio, see page 11. Shutting down the projector The projector automatically displays a black screen after no active source is detected for 30 minutes. This black screen helps preserve the life of the projector. The image returns when an active source is detected or a remote or keypad button is pressed. Screen Save You can make the black screen appear after a preset number of minutes by turning on the Screen Save feature in the Settings>System menu. See page 24. Power Save The projector also has a Power Save feature that automatically turns the lamp off after no active sources are detected and no user interaction with the projector is performed for 20 minutes. By default, this feature is off. See page 24. Turning off the projector You can turn the projector off simply by toggling the power switch to the off position. You can also press the remote’s Power button to place the projector in the Off state while it is running. When the Power button is pressed twice (once to start the power-down process and a second time to verify that you want to power the projector off), the lamp turns off and the LED blinks green for one (1) minute while the fans continue to run to cool the lamp. While the LED is blinking green, the projector does not accept any keypad and remote control input. When the lamp has cooled, the LED lights solid green and the fans slow down to minimal speed. To turn off the projector, toggle the power switch to the off position. NOTE: Once the projector has been toggled off, you must wait for one (1) minute before turning the projector on again. This allows the lamp to properly cool. However, if the remote was used to power the projector to the Off state you do not need to wait one minute to turn it on again. Troubleshooting your setup If your image appears correctly on the screen, skip to the next section. If it does not, troubleshoot the setup. The LED on top of the projector indicates the state of the projector and can help you troubleshoot.
15 Table 1: LED behavior and meaning LED color/behavior Meaning Solid Green The power switch has been toggled on and the software has initialized or the projector has been powered off via the remote.
