This projector can be used together with other projectors managed using the accompanied Sharp Advanced
Presentation Software—Professional Edition to create a videowall projection. Whereas conventional videowall
technology required the use of an image distributor, this projector videowall feature enables easy image settings
from a PC when inputting a single video source. This function greatly simplifies videowall setup.
RS-232C OUTPUTS also realise the simple daisy chain connection. The master projector directly connected to the
computer can make the daisy chain connection with multiple slave projectors. For details on setting master or
slave, see page 

.

• Use a videowall projector stand, sold separately, when using this function.
• Image quality may deteriorate when picture signals are input through multiple projectors in a daisy chain

connection.

• For more information on this feature, see the operation manuals accompanying the Sharp Advanced Presentation Software—

Professional Edition.

• When UXGA signal is displayed, the videowall can not be set by Sharp Advanced Presentation Software—Professional

Edition.
