Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.
■Make sure you are within 20 feet of the projector, and within 
range of the projector’s front or back sensor (approximately 30° to 
the left or right and 15° above or below).
■The remote control batteries may not be installed correctly or may 
be low on power. Replace the batteries as described on page 48.
■Dim the room lights and turn off any fluorescent lights. Make 
sure the projector is not in direct sunlight. Strong lighting, 
especially fluorescent lights, may affect the projector’s infrared 
receivers.
■Turn off any nearby equipment that emits infrared energy, such 
as a radiant room heater.
You have lost the remote control.
You need the remote control to access many projector features. If you 
have lost it, you can order another from Epson. See page 92 for details 
about ordering.
You can’t control the mouse pointer with the remote 
control.
■Make sure the USB mouse cable is securely connected to both 
your computer’s USB port and the projector’s USB port. For 
details, see page 19.
■Make sure RS232C is selected as the COM Port setting in the 
Extended menu. See page 60. 
■To use the USB mouse connection on a PC, your system must 
have a “clean” installation of Windows 98, Windows Me, 
Windows XP, or Windows 2000. The connection may not work 
correctly if your system was upgraded from Windows 95. 
						

							92Solving Problems
■If you’re running Windows 98 or Me, you may need to install 
USB drivers from your Windows CD-ROM. After you install the 
drivers, restart both the computer and the projector to 
resynchronize the setup.

Compatible Computer Display Formats
You can connect the projector to a wide range of computers, including 
PCs and notebooks, Apple Macintosh, Power Macintosh series 
(including G3, G4 and G5 systems), PowerBook computers, many 
iMac and iBook series systems, and high-end workstations such as the 
Sun
® SPARCstation.™ 
Although images are displayed at the projector’s native resolution of 
1024 × 768 pixels (PowerLite 81p) or 800 × 600 pixels (PowerLite 
61p), Epson’s patented SizeWise chip supports computer display 
formats ranging from VGA through UXGA.
To project images output from a computer, the computer’s external 
monitor signal must be set at a refresh rate (vertical frequency) that’s 
compatible with the projector; see the following table for compatible 
formats. For best results, the computer’s resolution should be set to 
match the projector’s native resolution (1024 
× 768, or 800 × 600). If 
this resolution isn’t available, select one of the other compatible 
formats:
■Windows:
Right-click the desktop, select 
Properties, click the Settings tab, 
and select a compatible resolution. (For a notebook displaying 
through an external monitor port, you’ll need to click the 
Advanced button on the Settings tab, then adjust the resolution 
of the external monitor.) 
■Macintosh OS X:
From the Apple menu, select 
System Preferences, then click 
Displays. Make sure the VGA Display or Color LCD dialog box 
is selected, then click the 
Display tab and select a compatible 
resolution. 
■Macintosh OS 9.x:
On the Apple menu, choose 
Control Panels, then click 
Monitors or Monitors and Sound. Click the Monitor tab and 
select a compatible resolution for your external monitor. 
You may need to modify existing presentation files if you created them 
for a different resolution. See your software documentation for details.
