Postium OBM-U550L 55-Inch 4K Quantum Dot LED Monitor with 12G-SDI, Dual Link 6G, Quad Link 3G

Postium OBM-U550L 55-Inch 4K Quantum Dot LED Monitor with 12G-SDI, Dual Link 6G, Quad Link 3G

The Postium OBM-U Series is designed for UHD/4K production and broadcast QC monitoring and encompasses five models from 9” to 55”. The OBM-U090 and U171 display UHD/4K signals scaled-down to native 1920x1080 resolution. The U-240 and U550L both utilize native 3840x2160 UHD resolution and the U311 is native 4096x2160 4K-DCI resolution.

All five models are equipped with standard 12G/6G/3G-SDI input interfaces (x2) and HDMI 2.0 input and support both 4K Quad Link 2-Sample Interleave and 4K Quad Link Square Division signals via SDI and SFP (no SFP input on OBM-U090). Analog Composite/Component I/O supported in OBM-U090 ONLY.

Closed Captioning decode and display for CEA-708(HD-SDI closed captioning standard) and CEA-608(SD-SDI closed captioning standard) is supported via SDI input. The OBM-U series accepts up to 3840x2160/24,25,30,50,60p and 4096x2160/24.25.30,50,60p signals.

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.

3D Look-up Table import is supported 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. 32ˆ³, 33ˆ³, 64ˆ³, 65ˆ³ cube file are supported.

In addition, the OBM-U series has Built-in Camera Log to Linear conversion LUTs from various camera manufacturers including Log-C, C-Log / S-Log2, S-Log3 / J-Log1 and more.

High Dynamic Range (HDR) Emulation applies a High Dynamic Range display gamma curve to HDR content. The OBM-U Series supports PQ EOTF (SMPTE ST 2084), Hybrid Log Gamma and S-Log3. Postium’s HDR function allows users to view both highlights and shadow details within scenes simultaneously, thus resulting in more natural and realistic reproduction.

SDR/HDR Display modes provide both full-frame HDR and SDR viewing as well as simultaneous side-by-side splIt'screen comparison.

Color Space / Dynamic Range / Gamma Comparison (Side by Side, Wipe position) allows users to compare different color spaces, gammas, HDR / SDR, camera logs, and other color settings side by side simultaneously. The comparison area can be selected and moved with a vertical wipe pattern.
