After projection starts, select the correct source (either 

Computer1

 or 

Computer2

)

 

when you want to project this source. See page 30.

If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 28 for instructions.

If you want to see your presentation close-up as well as on the 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 to turn off projection on the screen. 

Simultaneous display is possible only when the computer is connected 
to the projector’s 

Computer1/Component Video1

 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 28 for instructions.
