Stand Alone Calibration - NEC MultiSync PA271Q User Manual

Stand Alone Calibration

Stand Alone Calibration Function
This function allows calibration of the monitor without using computers. To open Stand Alone Calibration OSD menu, select
Calibration (see page 18) on the OSD or connect a supported USB color sensor on SENS/MEM port.
Select a function on the menu and follow the instructions on the OSD message.
Self calibration
This function updates the display's internal color processor reference data to use measurements taken using your color
sensor instead of the original factory measurement data. Your color sensor's measurements will become the reference for all
color settings in the display and all presets will be updated accordingly. When a supported USB color sensor is connected to
the SENS/MEM port, the monitor measures and calibrates automatically. Please place the USB color sensor on the center
of the monitor screen and follow the instructions in the OSD messages. If using a non-supported color sensor, such as near
range color analyzers, you can manually input the measured Y/x/y data in the OSD. All picture modes are calibrated when this
calibration data is updated; there is no need to re-calibrate when you use other picture modes or edit the picture modes.
Reset calibration
Deletes the result of the "Self calibration" function and initializes the internal optical data to the factory calibrated data. Effective
for all picture modes by single operation.
Validation
Measures the color patches with the USB color sensor and verifies the calibration result. The result of the validation is indicated
as the average of color difference (dE). Larger values mean that the difference of the measurement values between the built-
in color sensor and the USB color sensor is high. In general, you can use the monitor without trouble when the value is 3.0 or
smaller, however, if the value is higher than you expected, please retry the "Self calibration" function.
White copy
This function measures the luminance and white point of the target monitor (A), and sets the values to the current picture mode
of this monitor (B). Using this feature reduces the variation between different displays allowing them to match each other more
closely.
