White copy
This function can be used to “copy” the luminance and white point from another monitor when used in a multi-monitor
installation. This process is done by measuring the color of a monitor and setting those measured values into the monitor being
adjusted. This can be useful in situations where it is necessary to match a monitor in color to neighboring monitors without
having to recalibrate all monitors.
Before starting, it is necessary to input a full-white video signal to all of the monitors. Select the monitor that will be used as the
Target – or source - of the copy operation (A).
This function will measure the luminance and white point of the target monitor (A), and set these values to the current Picture
Mode of the destination monitor (B).
You can also fine-tune the measurement result while checking the screen color. If you want to return to the measured value,
select re-measurement.
The Self Calibration function must have been previously performed before this function is available on the OSD menu.

Monitor A – SOURCE monitor of white point to copy.
Monitor B – This monitor which performs a copy.
