Please allow me to explain our standpoint as a monitor manufacturer.
Our aim is to show images on the screen precisely according to signal output
from video card.
When calibrating the EIZO ColorEdge LCD monitors with the ColorNavigator
software, the software calibrates the LUT in the monitor, not the LUT on a
video card. Therefore, the output from the video card remains linear. The
vcgt tag on icc profiles created by the ColorNavigator shows a linear line.
Such icc profile created by the ColorNavigator is automatically assigned into
Operating System when the calibration is finished. Then, as was shown at PMA,
the ColorEdge monitors show very smooth grayscale ramp image with Preview.
When applying other icc profile with non-linear output, the ColorEdge monitors
show banding with Preview. This means that ColorEdge shows images as per the
output from the video card.
We are fully aware that Photoshop is one of the most popular software for
graphics works. Therefore, you might not be so much interested in how Preview
shows.
Anyhow, as was mentioned, our interest is to show images precisely according to
how the video output intended to. For demonstrating grayscale ramp performance
on monitors, I would use rather primitive software like Preview which is a
standard software comes with the OS. (There was a little controversy on
Preview, though....)
As for the CG220 technology, please kindly take a look here.
