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 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.
[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] or the [PICTURE] menu → [DYNAMIC CONTRAST] → [CONTRAST 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 MODE].
6) Press qw to switch the item.
f The items will switch each time you press the button.
[1]
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.
[2]
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.
(Factory default setting)
f This setting item is common with the following menu item.
g The [PICTURE] menu → [DYNAMIC CONTRAST] → [CONTRAST MODE]
7) Press as to select [CONTRAST SYNC].
8) 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]

Note
f The contrast synchronization function will operate when all of the following conditions are fullled.
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].
g If all linked projectors have the [CONTRAST MODE] setting menu, the [CONTRAST MODE] setting is unied to [1] or [2], regardless of
the [CONTRAST SYNC] setting.
g If there is any projector that does not have the [CONTRAST MODE] setting menu, the [CONTRAST MODE] setting is unied to [1],
regardless of the [CONTRAST SYNC] setting.
f It is possible to set [CONTRAST SYNC] to [OFF] for the projectors that are linked but not to synchronize.
