Notes
The gamma is preset to [2.4] that is

provided by ITU-R BT.1886 at the
factory. With this setting, dark
portions may be seen darker than
with conventional CRT or LCD
monitors. If you wish to obtain the
same gamma as that when using a
conventional CRT or LCD monitor,
set this item to [CRT BVM] or [2.2].
If blocked-up shadows are seen,
adjust the brightness for optimum
viewing of black portions.
The [Gamma] setting is fixed at [2.6]

when an XYZ format signal is input.
The factory preset black luminance

(luminance when no signal is input,
or the 0IRE-level signal is input) of
the [CRT BVM] setting in the
Gamma menu is the same as the
black luminance of common CRT
monitors.
Adjust the brightness (black level)

according to the ambient light and
the black level of the image to be
reproduced. Adjust the contrast
(white level) according to the
ambient light.

About HDR display
The HDR display is a method to
faithfully display the brightness of
signals in which 100% or more level is
defined without compressing the high
brightness parts. You can check the high
brightness parts that exceed the
displayable brightness of the unit by
decreasing the contrast.
In the HDR display, the cooling fan

is forcibly rotated regardless of
outside temperature.
In the HDR display, the screen saver

is forcibly set. [Off] cannot be
selected.
In the HDR display, [Flicker Free]

cannot be selected. [On] is always set
for signals of vertical frequency 24
Hz, 25 Hz, 48 Hz, and 50 Hz. [Off] is
always set for signals of 30 Hz and 60
Hz.
The protective function for the

OLED panel activates and inserts the
black level in one field according to
the input signal.
When the signal to display high
brightness images on the larger part
of the screen is input, blinking may
occur due to the protection function.
This is not a malfunction. There is
no effect on the throughout.
Using the unit with the high

brightness display for extended
periods may cause eyestrain or
reduction of eyesight. Be sure to take
an occasional break when using it.
Follow RECOMMENDATION ITU-

R BT.1702 "Guidance for the
reduction of photosensitive epileptic
seizures caused by television" or
other guidelines to use.
In the HDR display, the display

surface may emit heat when high
brightness images are output. Do not
touch the surface.
Do not display static images that

contain high brightness display, time
codes, markers, or logos for
extended periods to reduce the risk
of burn-in. Consider applying a
display method with low level
signals, of 100% or less.
When [Format] is set to [3G/HD/

SD-SDI Auto], [HD/SD-SDI Auto],
[3G-SDI 444 XYZ 12], [Dual Link
444 XYZ 12], or [HDMI], and the
XYZ signal is input, the optimum
setting for the XYZ signal is fixed.
