Features of the ProjectorSome examples of the projectors many useful functions include:
• Projecting images from a computer connected via a network.
 Automatically sending 
email notifications if 
errors occur with the 
projector, such as if the 
lamp cuts out during 
projection.
Before using EasyMP, 
refer to the EasyMP 
Setup Guide and EasyMP 
Operation Guide.
Images 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.46) 
 The keystone distortion that occurs 
when projecting from the side of 
the screen can also be corrected. 
(Vertical correction and horizontal 
correction  p.47) 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.48)
 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.49
Images 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.51Network CorrespondencePosition adjustment function for a variety of projection screens

understand.  p.66The projector can display images at high resolutions with a high degree of 
luminance.
In addition, images can be switched to low luminance if they are too bright 
when projecting in dark rooms or onto small screens.   p.89Colour mode function
