Measure and set the white point

You can use Monitor Profiler to measure and set the white point (RGB) settings that result in the desired white point.

The white point defines the exact white that the monitor displays.

Warm White (5000K) - Also known as D50, is a yellowish white, recommended for image reproduction on CRT monitors. 5000 K is also the recommended viewing light for soft-proofing.
Medium White (6500K) - Also known as D65, is a daylight white, recommended for image reproduction on CRT or LCD monitors if you prefer a white that is cooler than Warm White.
Cool White (7500K) - Is a bluish white, for situations that specifically require a bluish white.

When you calibrate the white point, adjust only the white point and no other monitor settings. The white-point controls might be physical buttons on the monitor or an on-screen display (OSD) that appears on the monitor. After you calibrate the white point, you might need to adjust the brightness.

Correctly position the spectrophotometer for measuring.
If you use an OSD, position the OSD away from the spectrophotometer (in a corner of the screen, for example).
Locate the white point controls on your monitor.
The control labels might be for white point, RGB, or color settings. There might be a single white point control or there might be three controls for Red, Green, and Blue.

If your monitor has a single white point control:
1. Adjust the control until the measured white point value matches the target value as closely as possible. After each adjustment, wait a few seconds for the spectrophotometer to measure and display the results.
2. Skip to step 9.
If you the monitor has three controls for Red, Green, and Blue:
1. Find the control with the middle value.
2. Set the other two controls to that value as well.
3. If these settings result in a noticeable color cast, reduce the dominant color (for example, reduce Red if the cast is reddish) to remove the cast.
4. If the color cast persists, set Red, Green, and Blue to 20.
Do one of the following:
- If the measured white point value is higher than the target value, either increase Red or reduce Green and Blue together (keeping the same value for Green and Blue), until the measured white point value matches the target value as closely as possible.
- If the measured white point value is lower than the target value, either reduce Red or increase Green and Blue together (keeping the same value for Green and Blue), until the measured white point value matches the target value as closely as possible.
Adjust Green and Blue to match the target white point as closely as possible.
You might not be able to match the target value exactly.
If the measured luminance no longer matches the target value, adjust the brightness control until it does. (Changing the white point can change the luminance.)
If the measured luminance is still too low at the maximum brightness setting, and your monitor has controls for Red, Green, and Blue, gradually increase all three controls, maintaining the same ratios, until the measured luminance matches the target value.
