The Blackmagic Design UltraStudio Mini Monitor 12G is a compact, single-cable Thunderbolt 4* playback interface that delivers broadcast-quality 10-bit 12G-SDI and HDMI 2.0 video from your laptop or desktop — no wall adapter, no rack space, no compromise on signal quality. It connects over one Thunderbolt cable, draws 15W from the bus, and outputs Ultra HD up to 2160p60 to professional monitors, production switchers, and downstream broadcast gear.

* Requires a computer with a Thunderbolt 4 USB-C port.

What sets this model apart from a standard SDI output box is the dedicated fill and key SDI outputs. Broadcast graphics operators running DaVinci Resolve, Adobe After Effects CC, or any supported CG application can key live graphics directly into a production switcher without any additional hardware — all from a device that fits in a jacket pocket.

Why Broadcast Engineers Choose the UltraStudio Mini Monitor 12G

📡

Fill + Key SDI Outputs

Two dedicated SDI outputs — one fill, one key — let broadcast graphics operators composite CG layers directly into a live production switcher without a separate hardware keyer.

⚡

Thunderbolt 4 — Truly Bus Powered

One Thunderbolt 4 cable carries both data and 15W of power. No AC adapter. Works with any Apple Silicon Mac or Thunderbolt 4 / Thunderbolt 5 Windows and Linux PC.

🎬

10-Bit 12G-SDI + HDMI 2.0 with Deep Color

Broadcast-grade 10-bit output on both connections. HDMI 2.0 supports Deep Color. SDI runs all rates from 270Mb SD through 12G Ultra HD on the same multi-rate output.

🖥️

Ultra HD Up to 2160p60

Full Ultra HD and 4K DCI support up to 2160p60 via SDI. Multi-rate switching across SD, HD, 2K, Ultra HD, and 4K within the same playback workflow.

🎧

16-Ch SDI Audio + 8-Ch HDMI Audio

16 channels of embedded SDI audio and 8 channels of HDMI audio, both at broadcast-standard 48 kHz / 24-bit — no separate breakout interface required.

🎨

HDR + Rec. 2020 — Hardware Colorspace Conversion

HDR static metadata packing with HLG and PQ transfer characteristics. Real-time hardware colorspace conversion between Rec. 601, Rec. 709, and Rec. 2020 — on the device, not the CPU.

🔗

DeckLink API — Every App Just Works

UltraStudio Mini uses the DeckLink API, so almost all professional video software works natively. Install the Blackmagic Desktop Video driver, open your app, and your outputs are live — no patching, no workarounds.

🎞️

Full Codec Stack for Playback

Apple ProRes 4444, ProRes 422 HQ/LT/Proxy, DNxHR, DNxHD, uncompressed 10-bit 4:2:2 and 4:4:4, HEVC, DPX, XDCAM, DVCPRO, AVCHD, and AVC-Intra — whatever your timeline contains, it plays back to SDI and HDMI without transcoding.

📺

Mac, Windows and Linux

Full cross-platform support for macOS 15 Sequoia and macOS 26 Tahoe or later, Windows 10 and 11, and Linux — using the same free Blackmagic Desktop Video driver across all platforms.

Get News Editing and Replay in DaVinci Resolve

The DaVinci Resolve cut page has exciting editing, media player and replay features built for broadcast. DaVinci Resolve handles virtually any video file format, so you can play any files your client gives you. For broadcast graphics, DaVinci Resolve can play video files that have an alpha channel — and they will be output as a 10-bit SDI fill and key directly through the UltraStudio Mini Monitor 12G.

The multi source viewer allows visual media browsing so that any clips matching in time are displayed in a multi-view. New on-air controls allow the key output to enable the downstream keyer in a switcher, so a single button can automate the play-out to air. DaVinci can even add an automatic stinger. It is the perfect solution for news editing and live replay workflows.

Extremely Fast Thunderbolt 4 Connection

All UltraStudio Mini models include fast Thunderbolt 4 with video playback plus power — all over a single cable. Thunderbolt 4 provides massive data speeds, delivering enough bandwidth to handle high resolutions, deeper bit depths, and advanced frame buffer formats including 4:2:2:4 and 4:4:4:4. It even supports real-time conversion of alpha channels out to 10-bit 12G-SDI fill and key outputs.

UltraStudio Mini uses the DeckLink API, so almost all professional video software works natively without configuration. Just install the Blackmagic Desktop Video driver, open your application, and your SDI and HDMI outputs are live.

Thunderbolt 4 single-cable bus-powered connection — UltraStudio Mini Monitor 12G for Mac Windows Linux

Supports Independent Fill and Key Outputs

With dual 12G-SDI video outputs, the UltraStudio Mini Monitor 12G connects directly into live production switchers so graphics can be overlaid with full transparency. Internally, there is hardware support for both RGBA and YUVA frame buffers. With RGBA graphics, video frames automatically transcode RGB pixels to YUV 4:2:2:4 video on both fill and key outputs at full 10-bit precision.

The two SDI outputs connect to a live production switcher where they are keyed over video. The key output ensures smooth blending of transparent elements in the image — making the UltraStudio Mini Monitor 12G ideal for broadcast graphics, lower thirds, and stingers in live production.

Get True 10-Bit Broadcast Video Quality

UltraStudio Mini Monitor 12G true 10-bit broadcast video quality — uncompressed SDI output

UltraStudio Mini Monitor 12G is designed to support the highest quality video. Most software supports playback to all popular video formats — Apple ProRes, DNxHD, and 10-bit uncompressed — so you are never locked into a single file format. 10-bit is the most commonly used television standard because colors can be represented with four times the precision of 8-bit video.

Working in 10-bit uncompressed ensures every image is a perfect pixel-for-pixel clone of the original source — giving you the sharpest green screen keying, seamless VFX compositions, and superior color correction results on your broadcast reference monitor.
