4.4 Calibration methods (detailed)
A correct calibration of your monitor is the basis for a good profile.
The better you pre-adjust the monitor hardware to the desired display
characteristics, the better the quality of the resulting profile. By calibrat-
ing the monitor you will improve the representation of all colors because
the profile conversion will have to correct for less and smaller differ-
ences.
SpectraView Profiler offers three different calibration methods. At first
launch it will automatically select the highest level method available for
your monitor/video card combination. When you quit the application, the
calibration method you may have selected manually, will be stored and
recalled next time you use
SpectraView Profiler .
4.4.1 Hardware & combined HW/SW calibration
Hardware calibrateable monitors are connected to the computer via
a digital data connection. This could be a DDC/CI video cable or a
separate USB or serial cable.
SpectraView Profiler uses this connection
to directly control the monitor and to calibrate it automatically, based on
the results of your measurements.
This functionality is only available for selected, hardware calibrate-
able monitors (see „HW_Support_List.txt“ in the
SpectraView Profiler
program folder).
Hardware-calibrated monitor: Perfect distribution of tone
values all steps are distinguishable
Software-calibrated monitor: Depending on the quality
of the monitor, not all steps may be distinguishable,
especially in highlights and/or shadows
Software-calibrated monitor: The tonal distribution is
regular the grays are neutral
Uncalibrated monitor: The tonal distribution is irregular
and the grays show a color cast.
