The OBM-U240 24" Native UHD 4K 12G-SDI LCD Monitor with DCI 4K Support from Postium features a native 3840 x 2160 display, supports HDR and 3D LUTs, displays HD footage, and scales DCI 4K footage to fit the screen. It incorporates four SDI connectors, two of which support 12G-SDI and two that support 3G-SDI, enabling you to input 4K via a single 12G/6G connection or by quad-link 3G-SDI. The monitor also supports 4K over its HDMI 2.0 input, as well as SFP. The monitor supports HDR video with its 10-bit panel, and allows you to adjust its display gamma from 1.0 to 3.0.
Operation of the OBM-U240 is via the front panel buttons and controls. An on-screen menu allows you more detailed control. You can apply a 3D LUT to the image, and this also allows the monitor to match a variety of color spaces. You can choose to display a waveform and/or vectorscope overlay from the built-in signal analyzers on top of your image. A selection of framing guides and markers allow you to frame for a wide variety of aspect ratios. As befitting a professional monitor, it supports timecode and audio level display. You can power this monitor by an optional 12-volt power source via the 4-pin XLR connector, or by AC power using the included power cord.
- Image over single-link 12G-SDI - where the signal is carried over a single SDI cable
- Quad-link square division - where the image is broken into four quadrants on output from the camera and reassembled by the monitor
- Quad-link 2 sample interleave (2SI) - where the signal is assembled by the monitor from alternating pixels from each of the SDI streams
- The waveform provides an objective evaluation of your video signal. It displays the brightness of your image on an IRE scale, allowing you to see if your image will clip and where your black levels are.
- The vectorscope displays the signal on a graph so you can check the phase of your colors. The vectorscope function also verifies and checks the overall tint and hue of an image.
