Features of the ProjectorImages can be projected regardless of the location.
• The keystone distortion that occurs 
as a result of the projector being 
tilted using the front adjustable 
foot can be corrected.
(Automatic keystone correction 
 p.41) 
 The keystone distortion that occurs 
when projecting from the side of 
the screen can also be corrected. 
(Vertical correction and horizontal 
correction  p.42)
 If vertical keystone correction causes the 
height of  projected images to be too 
short, the height of the projection area can 
also be adjusted. (Height correction 
 p.43)
 The Quick Corner function can be used 
to correct the four corners of the 
projection area to make the images fit the 
screen exactly. 
 p.44Images can be projected in places without a screen with no loss of original 
colour.
This automatically adjusts image colours to their natural colours even when 
projecting onto surfaces such as blackboards and partitions.   p.46
Multiple projectors can be monitored and operations such as turning the 
power on and off and changing the input signal source can be carried out 
over a network by a single operator sitting at a computer. 
(EMP Monitor   p.93)
In addition, if a problem occurs with a projector, such as a lamp blowing 
while projection is in progress, e-mail notification messages can be sent by  
the projector to notify someone of the problem.

without flickering when watching a movie through DVD or other devices. 
 p.84

It accepts both digital and analogue signals from a computer. And it offers 
various types of connectors that meet your devices (such as component 
video
