Adjust RGB Gain
Controls
Help Index
Usual Setting
Adjust the RGB Gain controls of the monitor until the three columns in the RGB
Adjustment Graph are balanced.
The Purpose of This Step
To set the native white point of the monitor as closely as possible to your desired
Target White Point. In this way, the hardware is optimized and the software will not
need to adjust the White Point using the video card Look Up Table (LUT). This offers
optimal results.
The Long Answer
First, please realize that it is not necessary to go through the process of adjusting the
RGB Gain controls in many cases. If your Target White Point is the same as one of the
Color Temperature Presets available on the display, you can get very good results by
just using the preset. Also, it is not necessary to adjust your RGB Gains Controls every
time you calibrate your display. Usually the balance between color channels will
remain consistant for several months, though running this step allows you to check
the balance, and determine if you would like to make minor adjustments.
If you want exacting White Point control for matching side-by-side displays or
achieving the closest possible proofing matches, then this is the tool to use. However
it can be a tedious process until you become familiar with adjusting a specific display’s
on screen controls.
If you are calibrating an LCD display it is recommended that you compare the results
you obtain using a color temperature preset to the results when adjusting the RGB
controls. On some LCD displays, adjusting the RGB controls maybe unrewarding;
