31" Grade 1 True HDR 4K Monitor OBM-X310
  • True HDR with 1,000 nits
The OBM-X310 HDR function allows users to view both highlights and shadow detail of screen at the same time, thus resulting in more natural and realistic images.
The OBM-X310 supports PQ(ST 2084), HLG(Hybrid Log Gamma), and S-Log3.

High Dynamic Range image01
The OBM-X310 provides the function of dividing the picture side by side and comparing HDR and SDR between right half and left half.

  • Accurate Color Reproduction with Wide Color Gamut
Fully Support DCI-P3 Color Space with PQ(ST 2084) 1000nit HDR
The OBM-X310 provides the industry-leading wide golor gamuts.
This monitor complies with the DCI-P3 color space with gamut ratio 114% and gamut coverage 99%, and supports the BT.2020 color space. This ensures the colors are reproduced according to industry standards.

  • True Black with 1,000,000:1 High Contrast
The state-of-the-art LCD technology of the OBM-X310 enables deep blacks to be accurately displayed, and the black portion of an image is not degraded. The OBM-X310's amazing ability to express subtle details in the low-luminance area is equal to the OLED monitor.

  • Dual SFP Module Inputs supporting Quad-Link 4K over IP
The OBM-X310 has the dual SFP Input cages, which enable the monitor to accept and display the Quad-Link square division and 2-Sample Interleave 4K signals over IP supporting SMPTE ST 2022-6.

  • DCI 4K 4096 x 2160 Resolution
The OBM-X310 incorporates a 31" true 4K panel with 4096 x 2160 pixel resolution.
Thanks to aspect ratio is 17:9, the images are mapped without scaling processes, so it is ideal for editing, referencing, and color grading.

  • No Halo Effect
The OBM-X310 employs the state-of-the-art Dual Cell(Dual Layer) LCD panel. By stacking two LCD panels, the dual-layer LCDs modulate light emitted by the backlight at least twice prior to reaching a viewer's eyes. It makes blacks appear deeper and darker on those parts of the screen. The OBM-X310 offers a true HDR performance without the halo effect in order to ensure accurate colors and brightness in every pixel.

  •  No Burn-In
OLED monitors have the risk of "burn-in", which is an effect of the image sticking on a screen even when the content changes. It is due to the characteristics of the material used in the OLED panel.
The OBM-X310, which employs the state-of-the-art LCD panel, is free from the burn-in effect.

  • Black Stretch
The Black Stretch increases the visibility of subjects in dark areas, not degrading image quality in bright areas.
This mode can be used to increase shadow detail without changing the absolute black level, and without affecting mid-tones.

  • False Color
This function evaluates the Luma(Y') level of the input image. If the certain Y' level is set, the pixels with the designated Luma(Y') level are displayed with the zebra pattern or the color pattern.
There are three modes in OBM False Color.

  • Gamut Error
The total range of the SDI 10bit signal is 0 to 1023. The range 0 to 3 and 1020 to 1023 are the reserved values for Sync, and the total video signal range is 4 to 1019.
In a video signal, each primary component should lie between 0 and 100% of the video range between black level and peak level (R and G and B). Ideally, video levels should lie within the specified limits so that programs can be distributed without adjustment.
100% White pattern: Y - 940, Cb - 512, Cr - 512
0% Black pattern: Y - 64, Cb - 512, Cr - 512
Expected Video Range: 64 to 940
In practice, it is difficult to avoid generating signals slightly out of range, and it is considered reasonable to allow a small tolerance. Therefore, the EBU recommends that the RGB components and the corresponding Luminance (Y) signal should not normally exceed the “preferred minimum/maximum” range of digital sample levels in the table below.

Gamut Error image 01

Type1 : Black Zebra

When the targeted color space is selected as BT.709, the pixels outside of the targeted color space are displayed as Black Zebra. The pxels 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.

Gamut Error image 02

Type2 : Black & White Zebra

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 pxels over Y Maximum, Chroma Maximum, RGB Maximum are displayed as Black Zebra, and the pixels below Y Minimum, ChromaMinimum, RGB Minimum are displayed as White Zebra.

Gamut Error image 03

Type3 : 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.

  • Closed Caption
The OBM OBM-X310 can display closed captions with an SDI input.
It supports the CEA-708(HD-SDI closed captioning standard) and CEA-608(SD-SDI closed captioning standard).

  • Remote Control via Ethernet
The OBM-X310 can be connected via Ethernet connection and controlled remotely on the network.

    • Supports 12G-SDI Single Link Square Division signal format
The OBM-X310 can display 12G-SDI Single Link 4K/UHD signals as well as 3G-SDI Quad Link signals. This is already a very useful feature, compared to competitors’ monitors.
Most of the single link 12G-SDI signals are displayed as 2-S.I. format on the screen. But, the single link 12G-SDI signals with Square Division format are increasing. In order to meet this requirement in the location and studio, the OBM-X310 supports both 12G-SDI Single Link 2-S.I. mode and 12G-SDI Single Link Square Division mode.

  • 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-X310 monitor meets the requirements of Return Loss specified in SMPTE ST 2081-1:2015, so that the OBM-X310 provides the high signal fidelity.
