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 in mm 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 
4362 mm and with a vertical offset of 165 mm.
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 25 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 in mm 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 (4500 mm), the 
closest match in the Average column is 4362 mm. Looking across this row shows 
that a 108-inch screen is required.

Projection dimensions
Refer to Dimensions on page 52 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 in situ 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 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:
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 16 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 17 for how to connect the 
projector to an S-Video device.
Least video quality
Composite Video is an analog video and will result in a perfectly acceptable, but 
less than optimal result from your projector, being the least video quality of the 
available methods described here.
See Connecting a composite Video source device on page 18 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. 
They are 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. 
						

							Connection 16
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 D-SUB IN 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 socket 
of the projector. 
Once connected, the audio can be controlled by the projector On-Screen 
Display (OSD) menus. See Adjusting the sound on page 34 for details.
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 15 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.
