SWIT BM-U325 | 31.5" 8K 4x12GSDI HDR Zero-Delay UHD Monitor with AI-Calibration

The SWIT BM-U325 is a 31.5-inch 4K UHD HDR studio reference monitor with 4×12G-SDI (8K-ready) connectivity, 10-bit panel, 99.4% DCI-P3 coverage, and AI-powered 3DLUT auto-calibration. Designed for high-end broadcast and post-production, it delivers zero-latency monitoring and advanced waveform, HDR, and IP control features.

The SWIT BM-U325 is a flagship 31.5-inch UHD HDR reference monitor engineered for demanding broadcast, live production, grading, and studio workflows. It features a 10-bit LCD panel with 3840 × 2160 resolution, 300 nits brightness, an impressive 3000:1 contrast ratio, and 99.4% DCI-P3 color gamut, ensuring highly accurate color reproduction and deep contrast performance.

With 4×12G-SDI inputs and 4× loop outputs, the BM-U325 supports single-link 4K, quad-link 4K, and quad-link 8K (SQD / 2SI) workflows. Additional connectivity includes HDMI 2.0, optional 12G-SDI via SFP fiber, and optional ST2110 IP via SFP, providing flexible integration into modern IP and SDI infrastructures.

The monitor supports HLG, PQ, and S-Log3 HDR EOTFs, along with automatic Payload ID detection, which intelligently configures HDR/SDR parameters, color space, and input range based on the incoming signal.

AI 3DLUT Auto Self-Calibration

The BM-U325 features integrated 3DLUT self-calibration without a PC, enabling precise color accuracy directly from the monitor. Users can also upload custom 3DLUT files via USB for tailored workflows.

Advanced Monitoring Tools

Professional image analysis tools include:

• Waveform (Y/Cb/Cr/R/G/B)
• Vectorscope
• Histogram
• Focus Assist
• False Color
• Zebra
• 16-channel audio meters
• Lissajous pattern monitoring

The monitor ensures zero audio/video latency, making it ideal for lip-sync critical environments such as live production and OB vans.
