10. When you have selected to calibrate an "LCD" display, check
if geometry and phase are well-aligned.
If they are well-aligned, the image is clear, crisp and stable.
If they are not well-aligned, the image will show dark bands
and/or vibrations, especially in the gray border of the image.
In that case, align display geometry and phase until the
image is crisp and stable (see "Notes:" below).
When done, click on Next.
When you have selected to calibrate a "CRT" display, this
step is skipped.
11. Set the display brightness to minimum. Then increase the
brightness until you can just distinguish all 4 patches on the
black background (see "Notes:" below).
When done, click on the Next button.
In this way, you have determined the black luminance target
value.
12. Now set the display contrast to maximum. Then decrease the
contrast until you can just distinguish all 4 patches on the
white background (see "Notes:" below).
When done, click on the Next button.
In this way you have determined the white luminance target
value.
13. If the selected display function is DICOM, the ambient light
compensation is determined now.
Therefore, hold the sensor approximately 5 cm (2 inches)
from the screen surface, as shown on the screen image.
Then, click on the Next button.
Hold the sensor like this until the next message appears.
14. An image of a sensor measuring head appears in the center
of the image. Hold the optical sensor on the white patch on
the screen until the end of the procedure.
This may take about half a minute. Do not remove the sensor
during this calibration period.
