The Blackmagic Design BMD-BDLKULSDMBREC3G, commonly known as the UltraStudio Monitor 3G, is a professional broadcast-grade monitoring and recording device designed for high-end video production, color grading, and live broadcasting workflows. This compact unit functions as both a high-quality monitoring output and a hardware recorder, bridging the gap between a computer's editing software and professional broadcast monitors or projectors. It connects to a Mac or Windows computer via Thunderbolt 3, providing a low-latency, high-bandwidth pipeline for video and audio signals. This allows editors and colorists to view their work on a calibrated reference monitor with pristine image quality, ensuring accurate color, contrast, and detail that cannot be reliably judged on a standard computer display.

A core feature of the UltraStudio Monitor 3G is its ability to output a wide range of professional video signals. It supports 3G-SDI, HDMI, and analog component video outputs simultaneously, offering compatibility with nearly any monitor or projector in a broadcast facility or post-production suite. It can handle video formats from standard definition all the way up to 4K DCI and Ultra HD at 60 frames per second, with support for high dynamic range (HDR) including HLG and PQ standards. Beyond monitoring, the device includes built-in hardware recording capabilities, allowing users to capture broadcast-quality files directly from the input signal to an attached USB 3.0 disk, which is invaluable for creating client deliverables, archiving feeds, or recording live outputs.

The device also features professional audio integration, embedding and de-embedding audio from the SDI streams and providing analog XLR and RCA audio inputs and outputs. Its dedicated front-panel display provides clear status information for all connected signals. For professionals working in DaVinci Resolve, the UltraStudio Monitor 3G offers deep integration, enabling flawless playback and real-time monitoring from the software's timeline. It serves as an essential tool for any serious color grading suite, live production truck, or edit bay, guaranteeing that the final video output meets the stringent technical standards required for broadcast, cinema, and streaming platforms.
