Settings — [PROJECTOR SETUP] menu
ENGLISH - 139
To use the contrast synchronization function and the shutter synchronization function, it is necessary to connect
the projectors targeted for synchronization in a loop with daisy chain connection using the <SERIAL/MULTI
PROJECTOR SYNC IN> terminal and the <SERIAL/MULTI PROJECTOR SYNC OUT> terminal. For details of
how to connect the projectors, refer to “Connecting example when using the contrast synchronization function/
shutter synchronization function” (
x
page 50).
Note
f
The contrast synchronization function and the shutter synchronization function can be used simultaneously.

Setting the contrast synchronization function
1) Press
as
to select [MULTI PROJECTOR SYNC].
2) Press the <ENTER> button.
f
The
[MULTI PROJECTOR SYNC]
screen is displayed.
3) Press
as
to select [MODE].
4) Press
qw
to switch the item.
f
The items will switch each time you press the button.
[OFF]
Select this item when the contrast synchronization function and the shutter synchronization function
are not used.
[MAIN]
Select this item when the contrast synchronization function or the shutter synchronization function is
used.
Set this item only on one projector out of the projectors that are linked.
The projector set as the [MAIN] will calculate the brightness level of the video signal to become
optimum on the whole combined screen for each frame. All the projectors targeted for contrast
synchronization will control the dynamic contrast function based on the calculation result.
[SUB]
Select this item when the contrast synchronization function or the shutter synchronization function is
used.
Set this item in all the linked projectors excluding the projector set as the [MAIN].
f
When anything other than [OFF] is selected, the diagnostic result is displayed in [LINK STATUS], indicating
if all the projectors including the projectors targeted for synchronization are correctly connected, and if
[MODE] is correctly set.
[LINKED]
All the projectors are correctly connected, and correctly set. They are in the condition that the contrast
synchronization function or the shutter synchronization function can be used.
[NO LINK]
The projectors are not correctly connected, or not correctly set. Check the cable connection status
and the projector setting for each projector that is linked.
5) Press
as
to select [CONTRAST SYNC].
6) Press
qw
to switch the item.
f
The items will switch each time you press the button.
[OFF]
Select this item when the contrast synchronization function is not used.
[ON]
Select this item when the contrast synchronization function is used.
Note
f
The contrast synchronization function will operate when all of the following conditions are fulfilled.
g
All the projectors to be linked are connected in a loop with the daisy chain connection. (Maximum 64 projectors)
g
[MODE] on only one projector that is linked is set to [MAIN], and [MODE] on all other projectors are set to [SUB].
g
[CONTRAST SYNC] on the projectors to perform the contrast synchronization is set to [ON].
f
It is possible to set [CONTRAST SYNC] to [OFF] for the projectors that are linked but not to synchronize.
Setting the shutter synchronization function
1) Press
as
to select [MULTI PROJECTOR SYNC].
2) Press the <ENTER> button.
f
The
[MULTI PROJECTOR SYNC]
screen is displayed.
