[MULTI PROJECTOR SYNC]
Set the contrast synchronization function and the shutter synchronization function.
The contrast synchronization function is a function to display a combined screen with a balanced contrast by
sharing the brightness level of the image signal input to each projector when a multi-display is constructed
by combining the projected image of multiple projectors. The shutter synchronization function is a function to
synchronize the shutter operation of the specified projector to other projectors, and the effect using the shutter
function including the fade in/fade out operation can be synchronized.
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 <MULTI SYNC IN>
terminal and the <MULTI 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 69).
Note
f The contrast synchronization function and the shutter synchronization function can be used simultaneously.
f The operation of the mechanical shutter is not included in the shutter synchronization function.
f The shutter synchronization function will operate even when there are different models within the linked projectors. However, the
synchronization function will not operate when there is a DLP projector that is constructed with one DLP chip such as PT-RCQ10 series
within the linked projectors.
f The menu items in the [PROJECTOR SETUP] menu → [MULTI PROJECTOR SYNC] are the same as the following setting items.
g The [PICTURE] menu → [DYNAMIC CONTRAST] → [USER] → [MULTI PROJECTOR SYNC]
g The [DISPLAY OPTION] menu → [SHUTTER SETTING] → [MULTI PROJECTOR SYNC]
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]
[MAIN]
[SUB]
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] or the [PICTURE] menu → [DYNAMIC CONTRAST] → [CONTRAST MODE] is correctly set.
[LINKED]
[NO LINK]
5)
Press as to select [CONTRAST MODE].
6)
Press qw to switch the item.
f The items will switch each time you press the button.

Chapter 4 Settings — [PROJECTOR SETUP] menu
Select this item when the contrast synchronization function and the shutter synchronization function
are not used.
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 image 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.
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].
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.
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.
Select this item when misadjusted black level (grayish black) is bothersome in the dark scenes.
Performs conventional correction to adjust the black level by decreasing the general brightness.
Select this item when topical radiance is required even in dark scenes.
Performs standard correction of the projector that does not decrease the brightness too much.
