Advanced Projection ■ Color Adjustment In overlapping projection, portions of images in the overlapping area that pick up other colors or are miscolored may be more noticeable. You can make this overlapping area appear less distracting by performing Color blending adjustment. 1 In the [Install settings] menu, select [Professional settings] > [Edge blending] > [Adjust] > [Color blending adjustment] > [Adjust]. 2 As you watch the image, adjust the value to eliminate unwanted colors in the overlapping area. First adjust red, green, and blue together by changing the [White] value, and then adjust [Red], [Green], and [Blue] values individually. 3 Repeat this adjustment on all projectors. ■ Black Level Adjustment In overlapping projection, dark colors are projected with less intensity than other colors in the overlapping area. You can make this overlapping area less distracting by adjusting the black level of non-overlapping image areas. Left image Right image Area where dark colors look lighter Position of end marker (hidden) D-area Blending area Here, the non-overlapping image area (from the end marker toward the center of the image) is called area "D." Normally, three areas are identified in the context of end markers: A, B, and C. In the following instructions, only area D is adjusted, and the widths of A, B, and C are left at the default value of 0. To prepare for adjustment, set [No signal screen] to [Black], start projection with no input signal, and turn off the room lights, so that you can check dark image areas. (P100) 160
