4.3 Calibration method
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 5 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 5.
4.3.1 Hardware 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 5 uses this connec-
tions 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 calibrateable
monitors (see „HW_Support_List.txt“ in the SpectraView Profiler 5
program folder).
LCD flat screens
LCD monitors normally use a backlight with defined lighting characteris-
tics. Colors are generated by filtering this light source with liquid crystal
filters.
