Connecting a USB Cable for Remote 
Presentation Control
You can use the remote control to click through slideshow-style 
presentations, such as PowerPoint, from up to 20 feet away. This 
makes it easy to deliver your presentation, since you won’t need to 
stand near your computer.
To use this function, you will need a USB cable, a system with a 
working USB port, and the full version of one of these operating 
systems: 
1. If you are using a desktop computer, disconnect the mouse cable 
from your computer.
2. Connect the square end of the USB cable to the projector’s   
USB port.
3. Connect the flat end of the cable to any available USB port on 
your computer.
4. If necessary, configure your laptop to work with an external 
mouse.
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 32 for instructions.

Connecting an External Monitor
If you want to see your presentation close-up as well as on the 
projection screen, you can connect an external monitor to the 
projector. This lets you view images on your computer monitor while 
the projector is in standby mode (plugged in but not turned on) and 
check your presentation or switch between picture sources even if 
you’ve pressed the 
A/V Mute button on the remote control to turn off 
projection on the screen. 
Simultaneous display is possible only when the computer is connected 
to the projector’s 
Computer (Component Video) port.
Make sure the projector and computer are off. Then connect the 
monitor’s cable to the projector’s 
Monitor Out port, as shown:
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 32 for instructions.
note
Some LCD monitors may 
not be able to display the 
image correctly. If you have 
trouble displaying the 
image, connect a multiscan 
monitor. If you’re projecting 
computer images, make sure 
the computer’s refresh rate is 
set to 65 Hz or greater.
