[NON-OVERLAPPED BLACK LEVEL]
Note
f [BRIGHTNESS ADJUST] is a function that makes the increased brightness in black level of the overlapping image area difficult to
notice when [EDGE BLENDING] is used to structure a multi-display screen. The optimal point of correction is set by adjusting [NON-
OVERLAPPED BLACK LEVEL] so the black level of the overlapping image area will be the same level as the non-overlapping area. If the
border area of the part where the image is overlapping and the non-overlapping part gets brighter after adjusting [NON-OVERLAPPED
BLACK LEVEL], adjust the border of the top, bottom, left, or right.
f The joining part may look discontinuous depending on the position you are looking from when a screen with high gain or rear screen is used.
f When structuring a multi-display screen using both horizontal and vertical edge blending, adjust [OVERLAPPED BLACK LEVEL] first before
making adjustments in Step 14). Adjustment method is same as the procedure of [NON-OVERLAPPED BLACK LEVEL].
f If only horizontal or vertical edge blending is used, set all items in [OVERLAPPED BLACK LEVEL] to 0.
f The [AUTO TESTPATTERN] setting will change in conjunction with the setting in [MULTI IMAGE PROJECTION] → [COLOR
ADJUSTMENT] → [AUTO TESTPATTERN], and the setting in the [DISPLAY OPTION] menu → [COLOR ADJUSTMENT] → [AUTO
TESTPATTERN].
f Significant change in operating environment temperature and brightness of input image may cause distortion of the overlapping area and
lead to blurry image. Avoid significant change in operating environment temperature and brightness of the input image when using edge
blending.
f It is recommended to set [WIDTH] at or above the factory default value for the overlapping area. The edges of the images may not be
properly blended if the value is set below the factory default value.
f Analog signals are not recommended when using edge blending.
