Dual 8" 6G-SDI Monitoring

The Blackmagic Design Smartscope Duo 4K mounts in 3 RU and provides two independent 8-inch screens, each accepting SD through 6G-SDI with reclocked loop-through outputs. It suits post-production engineers who need simultaneous picture and scope views on a single rack unit.

Installation Notes

Each monitor uses one SDI input and one loop-through output, so cabling follows standard BNC practice and auto format sensing removes manual mode selection. The 12 to 15 VDC supply and sub-20 W draw simplify rack power budgeting, while the Ethernet pair handles software control and updates without extra USB wiring.

Sustained Operation

Power consumption stays below 20 W across all supported formats up to 3840 x 2160p, keeping thermal load predictable during long grading sessions. Embedded 16-channel audio metering and selectable scopes run continuously without frame drops, and the reclocked loop outputs maintain signal integrity over extended cable runs.

Questions about this item

How can I confirm the Smartscope Duo 4K is displaying a 6G-SDI signal correctly after connecting it?

The front panel auto-detects the incoming format and shows the active SDI standard — SD, HD, 3G or 6G — on-screen. Select Waveform, Vectorscope or Parade to verify levels, chroma and RGB/YUV balance in real time.

What comes in the box with the HDL-SMTWSCOPEDUO4K and what must I supply separately?

The unit includes the dual 8-inch rack-mount monitor, a 12–15 VDC power supply and a USB 2.0 cable for updates. You must provide SDI BNC cables for each 6G-SDI input, an Ethernet cable for software control and a 3 RU rack space.

Which version of the Smartscope Duo 4K should I choose for a 4K 60p workflow?

The single model HDL-SMTWSCOPEDUO4K handles 3840 × 2160p up to 60 fps over 6G-SDI on each 8-inch screen. No higher-capacity variant exists; this unit covers the full 4K 60p range listed in the specifications.
