User Manual
White point
This menu provides the following standard white points:
● D65: The standard white point for most video productions as well as most computer graphics and design
work. It can also be used for lm production.
● D50: The standard white point for soft proong and print production. It is warmer than the D65 white
point.
● D55: The traditional white point for lm projection. It is the white point of the light output of a lm
projector’s lamp house.
● DCI-P3: The standard white point for a digital cinema projector.
Gamma/EOTF
This menu provides the following options:
● 2.2: A power function 2.2 gamma considered the standard gamma for use in daylight-level environment
illumination
● 2.4: A power function 2.4 gamma that was formerly the standard gamma for dim lighting environments.
For video work this gamma function has been superseded by the BT.1886 EOTF (electro-optical transfer
function)
● 2.6: A power function 2.6 gamma that is the standard gamma for cinema lighting environments with
essentially no ambient illumination
● BT.1886: An EOTF that has been dened by the International Telecommunication Union (ITU) as the
standard EOTF for professional high-denition video production and nishing
● sRGB: An EOTF based on the power function 2.2 gamma but designed to provide better lower-black
representation by transitioning from a curve to a linear function for the lowest grayscale values
Luminance
This menu provides the following luminance values as well as the option to select any luminance value
between 48 and 250 candelas per square meter (cd/m²):
● 250 cd/m²: The maximum luminance that can be calibrated to in the display
● 100 cd/m²: The standard luminance, originally dened by SMPTE, for video online and nishing work
● 120 and 80 cd/m²: Two options that provide bracketed values around 100 cd/m², based on the typical
environment illumination in VFX studios
● 48 cd/m²: The standard front-of-screen illuminance for motion picture presentation, equivalent to 17
(footlamberts)
After you have dened the calibration and conrmed the chosen values, calibration begins. The calibration
will take approximately 10 minutes when using the internal instrument, depending on the target luminance.
Calibration time may be longer with some external instruments. Do not turn the display o during the
calibration process. The preset is given a name based on the calibration targets selected.
NOTE: If an external instrument is connected, you are asked if you want to use the internal or external
instrument for calibration measurements. If you choose external, a line-up target is provided on-screen to
assist you in positioning the external instrument at the center of the screen.
