FAQ’s
1. What does calibrate mean?
To measure and correct by comparison with a standard, of the correct value
or each reading on a measuring instrument.
2. What is a profile?
A data file that describes the color behavior of a physical device (such as a
scanner, monitor, or printer) or that defines the color of an abstract color
space (such as Adobe RGG or ColorMatch RGB) in terms of a device-
independent color model (such as CIE LAB or CIE XYZ). Used by color-
management systems to define and match color.
3. What is the Curves window?
It provides a graphical display of the tonal response characteristics of the
monitor system. This includes representations of the monitor’s default
behavior, the desired behavior and the actual behavior.
4. What does color temperature mean?
It is a measurement of the color of white light, expressed in degrees Kelvin.
(The Kelvin scale is a measure of temperature, starting from absolute zero.)
The color temperature is the color of light a perfect black-body radiator
emits when heated to the temperature. Computer monitors typically have a
color temperature of 5000-9300 Kelvin: 5000 Kelvin is a yellow-white, 9300
Kelvin is a blue-white and 6500 Kelvin is a standard white point that matches
daylight at noon
5. What is native white point?
The native white point is the color temperature that the monitor hardware
exhibits without any software calibration applied. With some monitors it can
be adjusted with front panel controls, with others, it is fixed, and can only be
corrected with software adjustments.
6. What is ambient light?
Light from any source, other than the projection device, that reaches the
screen surface. The amount of ambient light affects the contrast, and
resolution of the screen.
7. How do I receive software updates?

updates are then posted in the ‘Software Upgrades’ section of our website,
where our customers can download them free of charge. The only thing the
