using presets may be more effective. Since LCD displays vary widely between
manufacturer and model it is not possible to make a universal statement about using
RGB controls on them. It is only posible to share the observation that RGB balancing
works well on some models while on others using presets is a better choice.
Two things to understand about RGB Gains balancing:
Red, Green and Blue levels interact. For example, increasing Red can also cause Blue
and Green to decrease. Every adjustment in one color will generally cause effects on
the other two. Make small adjustments.
Adjusting the RGB levels will also affect the White Luminance. If you are using
Measured Luminance mode you also have to watch the Current White Luminance in
relation to the Target White Luminance. If you match the White Point but your White
Luminance is off, adjust ALL THREE controls up or down to affect the luminance
without affecting the White Point balance.
Your goal is to make all three columns of the RGB Graph the same height. When the
columns are level, the top of the columns will be inside the black rectangle. Be aware
that the three colors interact with each other. For example, if Green is too high then
you may either reduce Green or increase Red or Blue. This will take a little
experimentation.
If possible, start with a preset that is close to your desired target. Make only small
adjustments in the RGB levels, 2-5 percent at most. Try not to adjust the control with
the highest level - instead adjust the other two to compensate in order to optimize the
White Luminance level.
Adjust the RGB Gain controls of the monitor as indicated by the levels on the bar
graph in the RGB Gains screen. For example, if the bar graph shows that Red is too
low, this means that you should increase the Red Gain (or decrease Green and Blue)
using the monitor controls. The levels graph is relative; adjusting the bars up and
down will only change their height in relation to the target rectangle, not the overall
graph.
