Tips for Better Networked Projection
■Avoid Exceeding Connection Limits
The maximum number of computers and projectors that can be connected varies 
by mode. When this limit would be exceeded,  it is not possible to add computers or 
projectors to a session. Thus, if the total number of computer users requesting to 
join a session at the same time would exceed the limit, their requests may be 
denied. In this case, an error message is displayed on the computers that could not 
join the session.
Similarly, if the total number of projectors users attempt to add to a session at the 
same time would exceed the limit, their  requests may be denied. In this case, a 
message is displayed on computers that c ould not add projectors, indicating that 
the projector list has been updated.
■ Operation if Devices Are Disconnected
If the connection is lost (for example, if  a LAN cable is accidentally disconnected), 
the affected computer or projector leaves  the session. Disconnection of essential 
computers or projectors will terminate a session.
For example, in Classroom Mode, disconnec tion of the presenter’s computer will 
terminate the session.
■ If Projectors Cannot Be Detected
If projectors cannot be detected or no image is displayed (except for the cursor) 
when you are attempting to connect to projectors in other subnets in Broadcast 
Mode, make sure the router supports multicast routing. Routers that do not support 
IPv4 multicast routing cannot be used to c onnect to projectors in other subnets in 
Broadcast Mode. Note that the router must be set up to route multicast addresses 
used by the application.
In Broadcast Mode, the following message is displayed if no signal is received from 
computers for 30 seconds. The projector  IP address and name are shown in the upper 
left.

Restrictions
■Router Connections
Although the application can also link com puters and projectors over a network via 
a router, operation is only ensured over one router hop. Note that before projecting 
from projectors in other subnets in Broadcas t Mode, you must configure the router’s 
multicast routing settings. For details, ask your network administrator.
■ Security Dialog  Box Projection
The application cannot be used to proj ect the Windows Security dialog box, 
normally accessed by  pressing Ctrl+Alt+Del.
■Screen Capture Software
It may not be possible to start the application while software that restricts screen 
captures is running.
■Animated Cursors
Animation of animated cursors is not projected.
■Alternative Cursors
Cursors used by some software may not be projected correctly. In this case, an 
arrow pointer is projected.
■Projection  Restrictions
Some windows and icons displayed on computers cannot be projected. Although 
switching the projection type to advanced w ill enable projection of more elements, 
not all elements can be projected even in this case.
Projected images may not always match the computer screens.
■ Network Bandwidth 
Some network conditions may  cause a delay in projection.
■Projection through Firewalls 
Some application functions may not be  available in environments where Windows 
Firewall or other software restricti ng network communication are installed.
■Application Display 
Application display may be distorted if you have adjusted the screen resolution in 
Windows.

■The Projected Image Is Blurred
Cause Countermeasure
The image is out of 
focus. Adjust the focus. (
P56)
The distance to the 
screen is too short. Check whether the distance to the screen is 
appropriate. If the distance is shorter than 
approximately 1.3 m (4.3), the projector cannot focus 
on the screen. (
P131)
The projector is not 
placed straight in front of 
the screen. Check whether the projector is placed obliquely to 
the screen. A slight error in the projection angle can 
be corrected through the keystone adjustment 
function. (
P65)
The projector has been 
moved to a place where 
the temperature varies a 
lot. When the projector is moved from a location where 
the temperature is low to a location where the 
temperature is high, condensation may form on the 
lens. The condensation will evaporate after a period 
of time and the projector will be able to project a 
normal image.
The lens is stained. Clean the lens. ( P194)
The tracking is bad. Adjust the tracki ng with the [Auto PC] or [Tracking] 
function. ( P55, P87 )
Video is blurred. Activate motion blur reduction. ( P112)
Motion blur reduction is 
not available. Motion blur reduction is not available when projecting 
JPEG files from USB flash dr
ives or over a network, 
or for networked multi-projection. Similarly, motion 
blur reduction is not available in image modes other 
than [Presentation] or [Dynamic].
The sharpness setting is 
not available. Sharpness cannot be adjusted during split-screen 
display.
