No Calibration - NEC SpectraView Profiler 5 User Manual

Profiler
User Manual
The downside of a software calibration, compared to hard- ware calibra-
tion is the reduction of tonal values by using 8 bit LUTs in the video
card. Depending from the extent of the correction, banding and reduced
definition in highlights and shadows can be then consequence. This
effect is annoying in technical vignettes, but it's not so visible in photos.

4.3.4 No calibration

In the worst case the graphic card does not support video LUT download
(some PC graphic cards). The monitor must then be characterized in it's
present state. Corrections for color temperature and tone curve are not
available in this mode. Also, adjustment of luminance and contrast can
only be done manually.
SpectraView Profiler 5 supports you with measurement values in setting
these parameters.
Should the graphic card contain a LUT when launching SpectraView
Profiler 5 it will be taken over and saved in the ICC- profile.
It is understandable that the results achieved with this method are far
from being optimal.
