Connecting to a ComputerConnecting to an External Monitor
Analogue RGB images and RGB video images from a computer that are 
being input to the [Computer1/Component Video1] port can be viewed on 
an external computer monitor at the same time they are being projected by 
the projector, so that the images can be checked at times such as when 
giving presentations.
If the images being projected are from a source that is connected to the 
[Computer2/Component Video2] port, these images cannot be output to an 
external monitor.
Connect the external monitor using the cable that is provided with the
