Connecting to a Computer
Eligible Computers
The method for connecting the projector to a computer using a cable is 
explained here. 
If using an EMP-765/755, see the Ea syMP Network Setup Guide for 
information on how to connect to  a computer over a network.
The projector cannot be connected  to some types of computer, or 
projection of images may not be possi ble even if actual connection is 
possible. Make sure that the comput er you intend to use satisfies the 
conditions given below.
 Condition 1: The computer must  have an image signal output port.
Check that the computer has a port su ch as an RGB port, monitor port 
or CRT port which can output image signals. 
If the computer has a built-in monito r, or if using a laptop computer, it 
may not be possible to connect th e computer to the projector, or 
alternatively you may need to purcha se a separate external output port. 
Refer to the documentation for your co mputer under a heading such as 
Connecting an external monitor  or similar for further details.
 Condition 2: The display resoluti on and frequency of the computer 
must be listed in  the List of Supported Monitor Displays. 
s Appendices: List of Supported Monitor Displays  p.115.
Some computers allow you to change the output resolution, so if 
necessary, change the resolution to one  that matches a setting in the List 
of Supported Monitor Displays, wh ile referring to the documentation 
provided with the computer.
CAUTION
When connecting the projector to a computer, make sure you check 
the following.
 Turn the power off for both the projector and the computer before  connecting them. If the power for either device is on at the time of 
connection, damage may result.
 Check the shapes of the cable conn ectors and the device ports before 
making the connections. If you try to  force a connector to fit a device 
port with a different shape or number of terminals, damage to the 
connector or port may result.
 Do not bind the power cable and th e connecting cable together. If the 
power cable and the connecting cable are bound together, image 
interference or errors in operation may result.
TIP
 You may need to purchase a separate adapter depending on the 
shape of the computers port. Refe r to the documentation provided 
with the computer for further details.
 If the computer and projector are too far away from each other for  the accessory computer cable to reach, use the optional VGA-HD15 
PC cable. Appendices: Optional  Accessories and Consumables 
s p.108

 The input source is determined automatically based on the input signals. 
Some computer signals may be reproduced with different colours 
from the original images. In such  case, set the input source to 
Computer.  sp.60

Connecting to a ComputerUser’s GuideUsing the Remote Control to Operate the Mouse Pointer (Wireless Mouse Function)
You can use the remote control as a 
wireless mouse to control the mouse 
pointer on the computer screen. To do this, you must use the accessory 
USB
g  cable to connect the computers  USB port to the [USB TypeB] port 
at the rear of the projector.

TIP
 If your projector is an EMP-765/755, the [USB TypeA] port on the 
back of the projector does not function as a USB hub.
 The USB cable can only be connect ed to computers with a standard 
USB interface. If using a computer which is running Windows, the 
computer must have had a full version of Windows 98/2000/Me/XP 
Home Edition/XP Professional installed. If the computer is running 
a version of Windows 98/2000/Me/XP Home Edition/XP 
Professional that has been upgrad ed from an earlier version of 
Windows, correct operation cannot be guaranteed. 
 It may not be possible to use the mouse function under some versions  of both the Windows and Macintosh operating systems.
 Some computer settings may have  to be changed in order for the 
mouse function to be used. Consu lt the computers documentation  
for further details.
