SWIT BM-U175 / BM-U245 4K/8K 12G-SDI Studio Monitors - 17.3

SWIT BM-U175 / BM-U245 4K/8K 12G-SDI Studio Monitors

The SWIT BM-U175 / BM-U245 4K/8K 12G-SDI Studio Monitors provide UHD 3840 x 2160 monitoring in 17.3-inch and 23.8-inch sizes for broadcast, post-production, and studio workflows. Both support single-link 4K, quad-link 4K, quad-link 8K, multiview monitoring, HDR/SDR evaluation, and professional 12G-SDI connectivity.

Choose the BM-U175 when rack integration and a more compact 17.3-inch display are priorities, or the BM-U245 when a larger 23.8-inch viewing area and native 10-bit panel are preferred. Both models support four independent 4K sources in multiview, making them practical 4K/8K studio monitors for control rooms, production facilities, DIT environments, and multi-camera monitoring.

Professional image-analysis tools include waveform, vectorscope, histogram, focus assist, false color, zebra, eye pattern, audio meters, and user 3D LUT support. Built-in calibration works with compatible color probes without requiring a computer, while Ethernet web control supports remote operation. Both sizes also provide HLG, PQ, S-Log3, multiple SDR gamma curves, and selectable BT.709, DCI-P3, and BT.2020 color gamuts.

Key Features

• Two Monitor Sizes: Choose the 17.3-inch BM-U175 or 23.8-inch BM-U245 while retaining the same core 4K/8K monitoring platform.
• Native UHD Panels: Both models display 3840 x 2160 resolution, with 300-nit brightness and 178-degree horizontal and vertical viewing angles.
• 4K and 8K Signal Support: Four 12G-SDI inputs support single-link 4K, quad-link 4K, quad-link 8K, and four-source multiview workflows.
• HDR and SDR Monitoring: HLG, PQ, S-Log3, and selectable SDR gamma options support modern production and finishing environments.
• 3D LUT Calibration: Built-in calibration software works with compatible X-Rite and JETI probes and supports user 17 x 17 x 17 LUT files.
• Professional Scopes: Waveform, vector, histogram, false color, focus assist, zebra, markers, and eye-pattern tools assist exposure and signal evaluation.
• Zero-Latency Mode: A processing mode below 1/100 of a frame supports critical lip-sync monitoring with 4K sources.
• IP Remote Control: Gigabit Ethernet enables browser-based source selection, picture adjustment, monitoring functions, and function-key configuration.
