Positioning your projector 15
Obtaining 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.
The maximum (native) resolution of the projector is 1024 x 768 pixels, which is a 4 to 3 
aspect ratio (expressed as 4:3). To be able to project a complete 16:9 (widescreen) aspect 
ratio image, the projector can resize and scale a widescreen image to the projectors native 
aspect width. This will...

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 Screen Diameter 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...

Connection 19
To connect the projector to a notebook or desktop computer (either through a
VG A  c a b l e  o r  VG A-DV I  c a b l e ) :   
The final connection path should be like that shown in the following diagram:
• A Mac adapter (an optional accessory) is needed if you are connecting legacy version 
Macintosh computers. 
• Many notebooks do not turn on their external video ports when connected to a projector. 
Usually a key combo like FN + F3 or CRT/LCD key turns the external display on/off....

Connection 20
Connecting a monitor
If you want to view your presentation close-up on a monitor as well as on the screen, you 
can connect the RGB signal output socket on the projector to an external monitor with a 
VGA cable by following the instructions below.
Note: The D-SUB output only works when an appropriate D-SUB input is made to the 
projector. Be sure the projector is connecting with the computer using the D-SUB IN 
socket, not the DVI socket.
To connect the projector to a monitor (either...

Connecting Video source devices
This section describes how to connect the projector to Video source devices using video 
cables. Video cable connections are recommended for Video presentations. 
This projector also supports data (graphic) PC connection using Wi-Fi. Wi-Fi connection is 
not recommended for Video presentations. See Wireless connection (optional) on page 18.
You can connect your projector to various Video source devices that provide any one of the 
following output sockets:
•...

Connection 22The audio connections illustrated in the following sections 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.
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...

Connection 23
• The projector is only capable of playing mixed mono audio, even if a stereo audio input 
is connected. See Connecting Audio on page 21 for details.
• Component Video is the only video output that delivers native 16:9 aspect ratio picture.
If you connect the projector to a High Definition TV (HDTV) tuner, the follow ing standards 
are supported:
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...

Connection 24
• 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 21 
for details.
