NEC PA231W user manual White Point Matching/Copy PA301W only, English-36

White Point Matching/Copy (PA301W only)

The white point can be copied from one display to one or more additional displays. Using this feature reduces the variation between different displays allowing them to match each other more closely.

Before proper copy can be performed, displays should warm-up for a minimum 40 minutes. If this calibration is started before the minute warm-up, a warning will appear on-screen (Figure C.3). White Point Matching/Copy does not compensate for a typical yellow color shift due to long-term LCD usage. If this yellow shift is noticeable, please do Self Calibration. See Page 34.

NOTE: Stand-alone calibration can only be performed using the X-Rite i1 Display 2 Sensor.

Refer to the KEY MAP (Figure A) when changing settings during the calibration.

Calibration can be performed in either portrait or landscape orientation.

NOTE: You can start calibration without computer as following.

When there is “NO SIGNAL” menu, press “LEFT”, then “RIGHT” button and hold down simultaneously. All White Pattern Image will be displayed. After this, Plug-in the USB color sensor to the side (or bottom when Portrait orientation) USB downstream port. You can start Copy from step number 4.
