  Positioning your projector
EnglishObtaining 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.
This projector is equipped with a movable lens. See Shifting the projection lens on page 16 for details. 
You can see the diagrams on pages 14 and 15 for the vertical offset values in the dimension tables that are 
measured when the lens is shifted fully up or down.
If you are using a 120-inch, 4:3-aspect-ratio screen, please refer to The screen aspect ratio is 4:3 and the 
projected picture is 16:9. The average projection distance is 494 cm.
If you have a 16:9-aspect-ratio screen and your measured projection distance was 4.5 m (450 cm), please 
refer to The screen aspect ratio is 16:9 and the projected picture is 16:9. The closest match in the 
Average column is 449 cm. Looking across this row shows that a 100-inch screen is required.
Checking the min and max projection distance values in the columns of Projection distance  [cm] 
on page 14 indicates that the 4.5 m measured projection distance will also fit the 90 and 110-inch size 
screens. The projector can be adjusted (using the zoom control) to display on these different screen sizes 
at the projection distance. Be aware that these different screens have different vertical offset values.
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 picture distortion on page 26 for details.

							16 Positioning your projector  
EnglishShifting the projection lens
The lens shift control provides flexibility for installing your projector. It allows the projector to be 
positioned off the center of the screen.
The lens shift is expressed as a percentage of the projected image height or width. It is measured as an 
offset from the projected image’s vertical or horizontal center. You can use the lever to shift the 
projection lens in any direction within the allowable range depending on your desired image position.
To use the lens shift lever:
1. Release the lever by turning it counterclockwise.
2. Move the lever to adjust the projected image position.
3. Lock the lever by turning it clockwise.
•  Please do not over-tighten the lever.
•  Lens shift adjustment will not result in a degraded picture quality. In the unlikely event that the image 
distortion is produced, see Adjusting the projected image on page 25 for details.
•  When the screen position is fixed

  Connecting with video equipment
EnglishConnecting with video 
equipment
You can connect the projector to any type of video e quipment, such as a VCR, DVD player, digital tuner, 
cable or satellite decoder, video ga me console or digital camera. You can also connect  it to a desktop or 
laptop PC or Apple Macintosh system. You need only  connect the projector to a source device using just 
one of the 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:
Preparations
When connecting a signal source to the projector, be sure to:
1. Turn off all equipment befo re making any connections. 
2. Use only the correct type cables for  each source with proper type plugs. 
3. Ensure that all cable plugs are firm ly fitted to the equipment jacks. 
Note that all cables shown in the following connection  diagrams may not be supplied with the projector (See 
Shipping contents on page 6  for details). Most cables are commerci ally available from electronics stores.
Connecting HDMI devices
HDMI (High-Definition Multimedia Interface) suppo rts 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. You should use an  HDMI cable when making connection between the 
projector and HDMI devices.

							18 Connecting with video equipment  
EnglishConnecting component-video/RGB devices
Connect your RGB source (DVD player or HD set top box) to the RBGHV inputs. You can also use a 
BNC- type component cable to connect your video devices. The audio connections are provided for 
informational purposes only. You can also connect the separate audio cable to a suitable audio amplifier.
Connecting video devices
You need only connect a composite Video cable from the same device. The audio connections are 
provided for informational purposes only. You can also connect the separate audio cable to a suitable 
audio amplifier.
•  If you have already made a Component Video connection between the projector and the video source 
device, you need not connect to this device again using a composite Video connection as this makes an 
unnecessary second connection of poorer picture quality. You need only connect using a composite 
Video connection if Component Video is not supplied on the video source device (for example, with 
some analog video cameras).
•  If the selected video image is not displayed after the projector is turned on and the correct video source 
has been selected, please check that the video source device is turned on and operating correctly. Also 
check that the signal cables have been connected correctly.
