3-17. Color Mix adjustment (Color coordinate Control)

This is to compensate the color difference for example, when red picture is displayed on multiple screens and reds are different as pure red vs orange red. An ideal condition is to have all the same pure red all over the screens but in case if orange-red appeared at once cube, then other cube can be color compensated to add some greens so that other red can be matched to the orange-red so thatall the colors can be matched same. Opposite operation, making orange to red is impossible.

Use 7 button while in Adjust mode, then click 4 for Red primary color and select ADJ.G for

the color to be mixed in case of above situation. The primary color would be 5 for Green, 6 for Blue and ADJ.R , ADJ.G or ADJ.B will select the color to be mixed.

4.Multiple Screen Wall system (example)

The picture shows 2x2 wall by one PC displaying picture, using internal magnification capability.

To make this image by internal signal processor, MAG need to be set to 2x2 and left top cube need to have Layout of 1 -1. The cube at right bottom needs to have Layout of 2 -2. Small position adjustment may be needed

to match the picture. When using internal magnification capability, still, all the cubes need to receive the same signal and DVI digital link will cover this part, using DVI cables.

When cube need to control or any adjustment needed, then ea ch cube need to have its ID # different from the others so that the command can be sent to the right ID # cube.

This picture effect (ex. 2x2) can be memorized as User Magnification Pattern (p-36).
