Camera Log Selection
The OBM-4KIP series have the built-in camera LUT of the various camera manufacturers. It allows users to load the following camera logs. Log-C, C-Log / S-Log2, S-Log3 / J-Log1
The more camera LUTs will be updated.
High Dynamic Range(HDR) Display Function
The OBM OBM-4KIP series provides the function to display the High Dynamic Range footage.
Postium HDR function allows users to view both highlights and shadow detail of scenes at the same time, thus resulting in more natural and realistic images.
The OBM U**8K/4K series supports PQ EOTF (SMPTE ST 2084), Hybrid Log Gamma and S-Log3.

Focus Assist
Focus Assist controls the aperture level of a video signal and displays images on screen with sharpened edges to help camera focus operation.
4K HDR Waveform Monitor and Vector Scope Display
modes enable users to monitor sources using the internal Waveform and Vector Scope individually or simultaneously.
The position of Waveform and Vector Scope can be moved between Top Left, Top Right, Bottom Right, and Bottom Left.

Adjustable Gamma
control allows for incremental compensation between gamma correction values of 1.0 and 3.0 — thereby ensuring that the decoded image isn’t too bright (no gamma correction) or too dark (over correction).

4K/QFHD Mode
The LCD panel resolution of OBM-U31IP/24IP is QFHD(16:9) 3840×2160, so if the input signal is 3840×2160 1:1 mapping is supported. If the input signal is DCI 4K(4096×2160), 1:1 mapping is not supported.

When the 4096×2160 signal is fed, if you select Zero Scan using [Scan] button on the front panel, the picture is scaled to be displayed on the panel of 3840×2025 resolution with maintaining 1.89:1 ratio..
[1:1 Scan]
When 1:1 Scan mode is selected with the [Scan] button in 1920×1080, 1280×720 mode, etc., it is placed in the center of the screen as above. A 1:1 mapped image is output.
Various Frame Markers/Mattes
Various Frame Markers/Mattes are available on the OBM-U series, including aspect, area, and center markers. In addition, the detailed display settings of each marker are allowed. For example, the color, brightness, horizontal/vertical position, and thickness of aspect markers can all be adjusted.

Input to the SDI In connectors of this monitor.
Up to 4-channel Single Link 12G/6G/3G/HD-SDI signals, 1-channel Dual-Link 6G/3G-SDI or 1-channel Quad-Link 12G/6G/3G-SDI signals can be input. Use the appropriate input connectors depending on the input signal, referring to the table below
Single Link 12G-SDI
Dual Link 2-Sample Interleave(2-SI)
Dual Link 2-Sample Interleave(2-SI)Quad Link 2 Sample Interleave (2SI)
Each link contains a full image at 1/4 resolution. 2SI mode uses four Sub-image and alternates the samples every two pixels and every line instead of slitting the image into four quadrants.

Meets the Return Loss Standard, SMPTE ST 2082-1:2015
In the professional broadcasting video industry, Return Loss is an important parameter that measures the reflected signal that bounces back from a terminated device. If the broadcast monitor has the poor return loss, the level of reflected signal negatively impacts the signal integrity of the loop-out signal.
The OBM-U**8K monitors meets the requirements of Return Loss specified in SMPTE ST 2081-1:2015, so that the OBM-U**8K monitors provides the high signal fidelity.
<SMPTE ST 2082-1:2015 Requirements>
12G-SDI (ST 2022-6) over IP is supported in the OBM-U**8K series via an SFP interface, which allows the use of various SFP modules. The OBM-U series monitors can display the 12G-SDI over fiber and the 12G-SDI Single Link over IP through the integrated SFP interface
False Color
False Color indicates the Luma (Y) level of the input image. If a certain Y level is set, the pixels with the designated Luma (Y) level are displayed with a zebra pattern or a color pattern. There are display modes – Zebra, Variable, ARRI, and Comparison.
Zebra
This mode displays the Luma(Y') level of the input image in zebra pattern.
False Color Variable
This mode allows the user to adjust White clipping, Pink level, Green level, Black Clipping.
False Color ARRI
The color pattern is displayed with ARRI camera standard.
False Color Comparison
This function enables the user to divide the picture side by side, and compare the original image on the left half and the False Color image on the right half.
Gamut Error
Gamut Error Type can be observed in 3 modes.
Type 1
when the targeted color space is selected as BT.709, the pixels outside of the targeted color space are displayed as Black Zebra.
The pixels over Y Maximum, Chroma Maximum, RGB Maximum are displayed as Black Zebra, and the pixels below Y Minimum, Chroma Minimum, RGB Minimum are also displayed as Black Zebra.
Type 2
when the targeted color space is selected as BT.709, the pixels outside of the targeted color space are displayed as Black or White Zebra.
The pixels over Y Maximum, Chroma Maximum, RGB Maximum are displayed as Black Zebra, and the pixels below Y Minimum, Chroma Minimum, RGB Minimum are displayed as White Zebra.
Type 3
when the targeted color space is selected as BT.709, the pixels inside of the targeted color space are displayed as Mono, and the pixels outside of the targeted color space are displayed as the color. In this type, black and white area is not recognized.
Black Stretch
Black Stretch increases visibility in dark areas without degradation of image quality in bright areas. This mode can be used to increase shadow detail without changing absolute black level and without affecting mid-tones
Black Stretch Off
Black Stretch On
Camera Log Mapped SDI Loopout
This function allows to load the camera log to the original image and then send the camera log mapped image to another monitor through SDI loop out.
