Software Calibration (Video Luts) - NEC SpectraView Reference 241 User Manual

User Manual
CRT monitors
Hardware calibratable CRTs need to be connected to the computer via
a digital data connection. That way color tem- perature, brightness and
contrast can be controlled. CRTs do not have any means to control the
gradation curves. The correction of the monitor gradation needs to be
done with video-LUTs in the video card. These are stored in 8 bit accu-
racy in the ICC-profile.
Hardware calibratable CRTs are not supported by SpectraView Profiler.
All the parameters a hardware calibration would set automatically can
be set manually, but instrumented with the help of „Hardware setup" in
SpectraView Profiler.
For optimal calibration and profiling results for soft proofing and high-
end image retouching, NEC recommends the use of hardware calibrat-
able LCD monitors.

4.4.2 Software calibration (video LUTs)

The monitor hardware needs to be set manually by the user, using
monitor controls or the on-screen-display (OSD). SpectraView Profiler
assists you in setting these parameters with measurements from your
monitor instrument.
Like in CRTs, the gradation settings are not accurate and need to be
corrected via video-LUTs. These are stored in the ICC-profile and
downloaded to the video card on system start-up.
