Dynamic Range
This adjustment lets you choose the standard SMPTE 2084 curve, that better match
the characteristic of your installation.
AUTO: this mode selects one EOTF SMPTE 2084 curve preset, between HDR1, HDR2,
HDR3 and HDR4, depending of signal content.
SDR: this mode is suitable for showing images without HDR contents.
HDR1: this mode is suitable for showing HDR contents with the SMPTE 2084 curve for
the following setup: screen dimensions of 100 inches and projector's lens set in wide
angle.
HDR2: as HDR1, but for screen dimensions of 120 inches.
HDR3: as HDR1, but for screen dimensions of 140 inches.
HDR4: as HDR1, but for screen dimensions of 160 inches.
This Menu is enabled only in Display Mode HDR and UserHDR. With the lens in tele
angle, it is necessary to select a preset greater than the default for that screen dimen-
sion. Example: in tele angle, with screen dimensions of 100 inches, selects the preset
HDR3.
Note: HDR behavor has been deeply revised. Since the launch of the NERO 4 HT mar-
ket, 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 situa-
tions in which it is used to project a 4K UHD HDR image.

ture. 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 ob-
jects can be separately identified.
