Note: In the OSD menu the labels displayed are “HDR/HLG N”, where in place of “N”
there is a number from 1 to 4. Anyone of them recalls the right preset, depending on
the Display Mode selected: “HDR”/“BrightHDR” or “HLG”/“BrightHLG”.
This Menu is enabled only in Display Mode “HDR”, “BrightHDR”, “HLG” or
“BrightHLG”. With the lens in tele angle, it is necessary to select a preset greater than
the default for that screen dimension. Example: in tele angle, with screen dimensions
of 100 inches, selects the preset HDR3.
Note: HDR behavior has been deeply revised.! Since the launch of the NERO 4 HT
market, one of the very first 4K UHD HDR products in its category, a vast range of
contents and signal sources have become usable. This vastness of content and
players has led to a profound revision of the HDR video behavior of NERO 4, now
optimized in all situations in which it is used to project a 4K UHD HDR image.
Brightness
Adjust the brightness of the image.
Use this control to adjust the darker areas of the picture (black level), without
aecting bright areas. Increasing the value will give more detail in darker parts of the
picture. For correct adjustment it may prove useful to display a gray scale test pattern
with at least twenty bands. Now try to reduce the brightness of the black band as
much as possible while ensuring that it can still be distinguished from the adjacent
band with brightness slightly higher than black. Alternatively use a scene composed
of black objects alongside other dark colored objects and try to ensure that all the
objects can be separately identified.

Contrast
The contrast controls the degree of dierence between the lightest and darkest parts
of the picture. Use this control to adjust the image's white level without aecting its
dark areas. For correct adjustment it may prove useful to display a gray scale test
pattern with at least twenty bands. Now try to increase the brightness of the white
band as much as possible while ensuring that it can still be distinguished from the
adjacent band with brightness slightly less than white. Alternatively use a scene
composed of well-lit white objects surrounded by light objects with lower level
lighting, and try to ensure that all the objects can be separately identified.
