Multiscreen Usage Examples
Example 1)
While projecting data sent from your computer on a screen, you can also display the other 
data such as a presenter script on your computer so that you can give a presentation 
without showing any data which you do not wish to let other participants see.
Ô
Example 2)
Using only a single computer, you can make an effective presentation by displaying different 
data stored in the computer via two projectors.
Example 3)
Sending images from a single computer to multiple projectors (up to four projectors), a 
larger image can be achieved by combining those images.
 Note
The examples shown here are illustrated as projectors are connected to a computer 
via wireless LAN, however, this also applies for the connection via wired LAN.
Note that the brightness or the color tint of the projected image may vary depending 
on each projector. This is an optical characteristic and not a malfunction. (Please 
adjust with the  Image adjustment  menu.)
 CAUTION
When you use multiple projectors for Multiscreen feature, make sure to leave 
suf cient space (more than OOcm) between projectors.  If you set the projector near 
the air exhaust of the other projector, it may cause damage to other units due to heat.
