1. Precaution

Always use set voltage.
AC 100 ~ 230V, 50/60Hz
DC 12V(OBM-U170) or DC 24V(OBM-U240)

All these instrucons should be read and understood before operang the unit.

If liquid is spilled on or impacts this product, please disconnect the product immediately
and seek professional help before connued use.

Unplug the unit from the wall outlet if it is not to be used for several days or more.

Keep unit in a well-venlated place to prevent overheang.

Do not install the product near any heat-generang equipment. Also, keep the product out of direct sunlight
or dusty areas.

Protect the power cord from being walked on or pinched parcularly at plugs, convenience
receptacles, and the point where they exit from the apparatus.

When using other DC 12V(OBM-U170) or DC 24V(OBM-U240) adapters instead of the standard adapter
provided by the manufacturer, please check the proper load capacity or current capacity and use an adapter
with stable voltage.

Do not overload AC outlets or extension cords. Overloading can cause fire or electric shock.

A very small proporon of pixels may be stuck, either always off (black), always on (red, green, or blue), or
flashing. In addion, over a long period of use, because of the physical characteriscs of the liquid crystal
display, such stuck pixels may appear spontaneously. These problems are not a malfuncon.

If a fixed picture such as a frame of a divided picture or me code, or a sll picture is displayed for a long me,
an image may remain on the screen and be superimposed as a ghosng image.

The permanent burn-in may occur for LCD panel if sll images are displayed in the same posion on the
screen connuously, or repeatedly over extended periods.
To reduce the risk of burn-in,
a. Turn off the character displays.
b. Turn off the power when not in use.
c. Turn off the power if the monitor is not to be used for a prolonged period of me.

be selected when the White is 1000 cd/m² in
HLG gamma.

- HLG 0.98(300) (Hybrid Log Gamma) : This mode

can be selected when the White is 300 cd/m² in

HLG gamma.

- HLG -1.0 / 1.1 / 1.2 / 1.3 / 1.4 / 1.5 : These modes

allow the user to apply HLG gamma from 1.0 up

OBM-U240

4K/QFHD Mode

When the 4096x2160 signal is fed, if you select Zero Scan using [Scan] buon on the front panel, the picture is
scaled to be displayed on the panel of 3840x2048 resoluon with maintaining 1.89:1 rao.

If you press [Scan] buon once more, [1:1 Scan] mode is selected.
To see the image on the right-end and the le-end area, the locaon of the image can be moved by rotang
the [SELECT/VOLUME] knob.

**Note -When QFHD/DCI 4K signal is fed, [Aspect] buon is not acvated.

The LCD panel resoluon of OBM-U240 is QFHD(16:9) 3840x2160, so if the input signal is 3840x2160,
1:1 mapping is supported. If the input signal is DCI 4K(1.89:1) 4096x2160, 1:1 mapping is not supported.

4K/QFHD Mode

The LCD panel resoluon of OBM-U170 is FHD(16:9) 1920x1080. So, when Zero Scan is selected, if the input
signal is QHD(3840x2160) it is scaled to 1920x1080(16:9), and if the input signal is DCI 4K(1.89:1) 4096x2160
it is scaled to1920x1012(1.89:1).

If you press [Scan] buon and select [1:1 Scan] mode, 1:1 pixel mapping of the original image is displayed.
The locaon of the image can be changed by rotang the [SELECT/VOLUME] knob.

**Note -When QFHD/DCI 4K signal is fed, [Aspect] buon is not acvated.

11. Other Functions

Versale 4K/QFHD Input Capability

The OBM-U170 and OBM-U240 are equipped with
standard 12G-SDI input interace(x2) , 3G/HD-SDI
input interface(x2) and support 4K Quad Link 2-Sample
Interleave signals and 4K Quad Link Square Division
signals.
The OBM-U170 and OBM-U240 can accept up to
3840x2160/24,25,30,50,60p and
4096x2160/24.25.30,50,60p signals.

Various 4K/12G Display Modes

Mode 1 : Single Link 12G

Mode 2 : Quad Link Square Division

Each link contains one square of the original image.

Mode 3 : Quad Link 2 Sample Interleave (2SI)

Each link contains a full image at 1/4 resoluon.
2SI mode uses four Sub-image and alternates the
samples every two pixels and every line instead of
sling the image into four quadrants.

4K Waveform Monitor and Vector Scope Display
These features enable users to monitor sources
using the internal Waveform and Vector Scope.
Waveform Wide mode is supported, and both
Waveform and Vector Scope can be displayed
simultaneously.

SFP opcal connector

The OBM-U240 and OBM-U170 have the SFP interface,
which allows to use the various SFP modules which
can fit any possible broadcast applicaons.

Adjustable Gamma

Gamma value is adjustable from 1.0 to 3.0 as user's
preference to monitor in the dark area of the picture.
Any pictures taken in either light or dark environment
can be easily watched or analyzed.

Focus Assist

This funcon controls the aperture level of a video
signal, and displays images on screen with sharpened
edges to help camera focus operaon.

Supports DCI P3 and ITU-R BT.2020 Wide
Color Spaces

The wide color gamut and the advanced 3D LUT
funcon enable OBM-U240 and OBM-U170 to
reproduce various color spaces accurately and the
excellent grayscale.
You can select from color gamuts such as DCI-P3,
ITU-R BT.2020, ITU-R BT.709, SMPTE-C, EBU, Nave.

Color Space & Gamma Comparison

(Side by Side, Wipe posion)
This unique funcon allows users to compare
the two difference color spaces and gammas
side by side simultaneously.
The area of the two pictures to be displayed can
be selected using a vercal WIPE paern.

Zebra

This funcon displays the Luma(Y') level of the input
image in zebra paern.

Various Markers

The OBM-U240 and OBM-U170 can display various
markers, including aspect marker, area marker, and
center marker. In addion, the detailed display
sengs of each marker are allowed. For example,
the color, brightness, horizontal/vercal posion,
and thickness of aspect markers can all be adjusted.
