Uniformity:
The color uniformity is guaranteed via internal calibration processes.
This uniformity correction is always done. When this box is checked, the luminance
uniformity correction is applied. The luminance uniformity correction can lead to a
slight loss in contrast.

Out of gamut indication:
Option to verify if parts of the image displayed on the
screen are out of gamut of the selected color working space.
The display unit has a larger color gamut than the broadcast standards. The image/
video which is shown on the screen is in accordance with the primaries and the
white point of the selected color working space. However, if the input signal contains
information which is out of gamut of the selected color working space, or when cer-
tain adjustments have been done which drive the shown image out the selected
color working space, the display unit will show the image information faithfully as
long as it is within the gamut of the display unit.
When “out of gamut indication” is checked, the display unit will mark the image data
which is out of the selected color working space by displaying a checkerboard pat-
tern. The fields of the checkerboard pattern change to the other color with a fre-
quency of 1 Hz. When R, G or B is above 100%, a Red&Black checkerboard pattern
is displayed. If R, G or B is negative, a Blue&Black checkerboard pattern is shown. It
is possible that on a specific part of the image data, one of the primaries is above
100% while another primary is negative. In this case both checkerboard patterns
are shown on top of each other in anti-phase.
First window:
These settings apply to window 1 only.
•
Gain:
The gain is a multiplication factor that acts directly on the input signal. Please
refer to the chapter “Terminology” and read the section on the Electro Optical Trans-
fer Function to understand the impact of this setting on the shown image.
•
Resizer settings:
Determines the algorithm that is used to display the luminance
information of the image on a different number of pixels on the screen. See “Resizer
filter menu” for more details.
•
Swap field dominance:
The display unit automatically detects the correct field
dominance for interlaced fields. When an error in video transformation would occur,
and the field dominance is not set according to the definition of the detected stan-
dard, the field dominance can be swapped manually.
Second window:
the explanations of the settings is the same as for window 1.
