How to determine the position of the projector 
for a given screen size
1. Select your screen size.
2. Refer to the table and find the closest match to your screen size in the left 
columns labelled 4:3 screen diagonal. Using this value, look across this row 
to the right to find the corresponding average distance from screen value in 
the column labelled Average. This is the projection distance.
3. On that same row, look across to the right column and make note of the 
Vertical offset value. This will determine the final vertical offset placement of 
the projector in relation to the edge of the screen.
4. 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 2 above, and offset by the value determined in step 3 above.
For example, if you are using a 108-inch screen, the average projection distance is 
4320 mm (170”) and with a vertical offset of 82 mm (3.2”).
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 and find the closest match to your measurement in the 
average distance from screen column labelled Average. 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 
screen diagonal 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 
Vertical offset value. This will determine the final placement of the screen in 
relation to the horizontal plane of the projector. 
For example, if your measured projection distance was 4.5 m (177”), the closest 
match in the Average column is 4320 mm (170”). Looking across this row shows 
that a 108-inch screen is required.

Projection dimensions
Refer to Dimensions on page 53 for the center of lens dimensions of this projector 
before calculating the appropriate position.
There is 3% tolerance among these numbers due to optical component variations. InFocus 
recommends that if you intend to permanently install the projector, you should physically test 
the projection size and distance using the actual projector before you permanently install it, 
so as to make allowance for this projectors optical characteristics. This will help you 
determine the exact mounting position so that it best suits your installation location.

Connecting video source devices
You can connect your projector to various video source devices that provide any 
one of the following output sockets:
 Component video
 S-Video
 Video (composite)
You only need to connect the projector to a single video source device; 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:
Best video quality
The best available video connection method is Component video (not to be 
confused with composite video). 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 17 for how to connect 
the projector to a component video device.
Better video quality
The S-Video method provides a better quality analog video than standard 
composite video. 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 18 for how to connect the 
projector to an S-Video device.
Good video quality
Composite video is analog video and will result in a perfectly acceptable, but less 
than optimal result from your projector. The other methods described above provide 
better video quality.
See Connecting a composite video source device on page 19 for how to connect 
the projector to a composite video device.
Connecting audio
The projector has one built-in mono speaker which is designed to provide basic 
audio functionality accompanying data presentations for business purposes only. It 
is 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 
speaker.
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 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. 
						

							Connection 17
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 VGA (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 VGA (D-Sub) adaptor cable 
(with a D-Sub type connector) to the COMPUTER IN1/COMPUTER IN2 
socket on the projector.
3. If you wish to make use of the projector (mixed mono) speaker in your 
presentations, take a suitable audio cable and connect one end of the cable to 
the audio output socket of the device, and the other end to the AUDIO IN 
socket 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 35 for details.
The built-in speaker will be muted when the AUDIO OUT jack is connected.
The final connection path should be like that shown in the following diagram:
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
connected. See Connecting audio on page 16 for details.
• If the selected video image is not displayed after the projector is turned on and the correct 
video source has been selected, check that the video source device is turned on and 
operating correctly. Also check that the signal cables have been connected correctly.

 If not, you will need to reassess which method you can use to connect to the 
device.
To connect the projector to an S-Video source device:
1. Take an S-Video cable and connect one end to the S-Video output socket of 
the video source device.
2. Connect the other end of the S-Video cable to the S-VIDEO socket on the 
projector.
3. If you wish to make use of the projector (mixed mono) speaker in your 
presentations, take a suitable audio cable and connect one end of the cable to 
the audio output socket of the device, and the other end to the AUDIO IN 
socket 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 35 for details.
The built-in speaker will be muted when the AUDIO OUT jack is connected.
The final connection path should be like that shown in the following diagram:
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
connected. See Connecting audio on page 16 for details.
• If the selected video image is not displayed after the projector is turned on and the correct 
video source has been selected, check that the video source device is turned on and 
operating correctly. Also check that the signal cables have been connected correctly.
• If you have already made a Component video connection between the projector and this S-
Video source device using Component video connections, you need not connect to this 
device using an S-Video connection as this makes an unnecessary second connection of 
poorer picture quality. See Connecting video source devices on page 16 for details.
