Postium OBM-U278K 27-Inch HDR 8K 12G-SDI/3G-SDI Monitor

The OBM-U278K incorporates 4 x 12G SDI inputs and active loop outs (x4), 1-HDMI 2.0 input, and 2-SFP cages. The OBM-U278K accepts up to 7680x4320/60/59.94/50p signals. HDR support includes EOTFs for PQ (SMPTE ST 2084), Hybrid Log Gamma and S-Log3 and wide color gamuts conforming to DCI-P3 and ITU-R BT.2020.

The OBM-U278K offers professional performance and features, including excellent quality black level reproduction and accurate calibrated colorimetry, making the OBM-U278K monitors ideal for 8K/4K live production, versatile studio monitoring applications, and field production applications. In addition, the OBM-U278K supports integrated 3D LUTs, Waveform, Vector Scope and a full broadcast feature set.

Display Functions
Wide Color Space Support including DCI-P3 and ITU-R BT.2020 is controlled with an advanced 3D LUT (Look Up Table) to reproduce various color spaces accurately with smooth, artifact-free grayscale steps. Available color gamuts are DCI-P3, ITU-R BT.2020, ITU-R BT.709, SMPTE-C, EBU, and Native.

Versatile 4K/QFHD Input Capability
The OBM-U** 8K series is equipped with standard 12G-SDI input interface(x4) and support 4K/8K Quad Link 2-sample inter-leave signals and 4K Quad Link Square Division signals.

The OBM-U** 8K Series can accept up to 7680x4320/23.98,24,25,29.97,30,50,59.94,60p and 8192x4320/23.98, 24, 25, 29.97, 30, 50, 59.94, 60p.

Custom 3D LUT File Import
The OBM-U**8K Series allow the user to import 3D Look-up Table for accurate and consistent color matching between individual displays as well as using customized ‘looks’ that have been created by 3rd party color-grading applications. 32^3, 33^3, 64^3 and 65^3 cube file is supported.

Camera Log Selection
The OBM-U**8K 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.

The LUT-converted content can then be output to downstream devices/monitors via the SDI loop out.

High Dynamic Range(HDR) Display Function
The OBM U**8K 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 series supports PQ EOTF (SMPTE ST 2084), Hybrid Log Gamma and S-Log3.

OBM-HDR provides the function of comparing HDR and SDR(Standard Dynamic Range) on the displayed image on the OBM series simultaneously.

Focus Assist controls the aperture level of a video signal and displays images on screen with sharpened edges to help camera focus operation.

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.

Gamut Error Type can be observed in 3 modes. In 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.

In 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.

In Type 3: Mono, 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 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.

4K HDR Waveform Monitor and Vector Scope Display modes enable users to monitor sources using the internal Waveform and Vector Scope individually or simultaneously.
