balance is the same for all sources. The color balance information is saved in memory in only one location, not for each source. However, when a lamp is changed, you should color balance again.
The goal of color balancing the displays is to match the brightness and white “color” of all the displays in video wall to each other, and then match the intermediate gray shade. Therefore, color balancing is accomplished with all displays turned on in the finished video wall. (If you have only one unit, color balancing is not very important.) Do not start color balancing until all lamps have been on for at least five minutes.
The color balance menu provides control over the individual RED, GREEN, and BLUE settings to balance the white color, as well as an ALL adjustment to control the overall luminance by changing all three colors together. Similar control for the RED, GREEN, and BLUE settings is provided to adjust the balance of the gray shades without affecting the white balance.
The down arrow key moves the cursor from All to Red, Green, and Blue in the White column, then to All, Red, Green, and Blue in the Gray column, then back to All in the White column again. The left/right arrow keys increase and decrease the brightness number. It is a common mistake to use the
For white balancing, the individual RED, GREEN, and BLUE color selections have a number between 0 and 31. Zero is the darkest and 031 the brightest.
For gray balancing, the individual RED, GREEN, and BLUE balance settings have a number associated with them between 0 and 7. Zero is the darkest and 007 the brightest.
The following chart shows the relationship of the menu item adjustments.
