SWIT BM-U175 | 17" 8K 4x12GSDI HDR Zero-Delay Reference UHD Monitor with Auto-Calibration

The SWIT BM-U175 is a 17.3-inch 4K UHD HDR reference monitor featuring 4×12G-SDI (8K-ready) inputs/outputs, zero audio/video latency, and automatic 3DLUT calibration without a PC. Designed for broadcast and rack integration, it supports HDR/SDR workflows, multi-view monitoring, and advanced waveform and audio analysis tools.

The SWIT BM-U175 is a professional 17.3-inch UHD reference monitor built for demanding broadcast, OB van, studio, and post-production environments. It features a 3840 × 2160 resolution 8-bit + 2FRC LCD panel with 300-nit brightness, 800:1 contrast ratio, and 91.5% DCI-P3 color gamut coverage, delivering accurate monitoring for both SDR and HDR productions.

The monitor supports HLG, PQ (Dolby Vision), and S-Log3 HDR EOTFs, along with SDR gamma selections (1.0–2.6) and multiple color gamuts including BT.709, DCI-P3, and BT.2020. With automatic payload ID detection, the BM-U175 intelligently configures HDR/SDR settings, color space, and input range based on the incoming signal.

Connectivity includes 4×12G/6G/3G/HD/SD-SDI inputs and loop outputs, supporting single-link 4K, quad-link 4K, and quad-link 8K (SQD or 2SI). It also offers HDMI 2.0 (4K60p) and optional 12G-SDI or ST2110 IP via SFP fiber modules. The monitor supports multi-view of 4 independent mixed inputs and provides per-window waveform, vector, audio meters, and EOTF/gamut selection.

The integrated automatic 3DLUT self-calibration system supports X-Rite i1 and JETI Specbos 1211 probes via USB, achieving calibration results of ∆E ≤ 1.0 without requiring a PC. Users can also upload custom 17×17×17 3DLUT cube files via USB.

For precision production monitoring, the BM-U175 includes:

• Waveform (Y/Cb/Cr/R/G/B with Nits marker)

• Vectorscope

• RGB/Y histogram

• Focus assist (R/G/B/Mono)

• Zebra and False Color

• 16-channel audio meters with selectable output

• Lissajous and 5.1+2 surround sound monitoring

• SDI eye pattern analysis for 12G signal quality

With zero video latency (less than 1/100 frame) for accurate lip-sync, remote IP web server control via LAN, TSL UMD & TALLY support, and included 19-inch 7U rack mount ears, the BM-U175 is a complete rack-ready UHD HDR monitoring solution.
