HDMI to Dual SDI Converter

The LUOM HDMI2SDI accepts a single HDMI source and delivers two simultaneous SDI outputs for broadcast monitors or long cable runs. It targets video professionals who need to distribute a 1080p camera or graphics signal to multiple SDI displays without adding latency. The unit handles 3G-SDI, HD-SDI and SD-SDI formats automatically and embeds stereo audio from the HDMI stream.

Driver-free setup with format detection

Installation is a simple plug-and-play connection: one HDMI Type-A input, two SDI BNC outputs and a USB port for power — no external adapter required. The converter auto-detects 3G/HD/SD-SDI standards and locks to the incoming HDMI timing. Common issues include forgetting to force an ATEM switcher to 720p@60Hz and chaining multiple converters of the same type, which the manufacturer advises against.

1080p maximum output resolution

The single specification that decides suitability is the 1080p ceiling on SDI output; the device will not pass 4K or higher frame-rate signals. Input supports up to 1080p@60Hz and a range of VESA timings, while SDI reaches 100 m at 3G, 200 m at HD and 300 m at SD bit-rates. Buyers needing 4K capture or bi-directional conversion should look elsewhere.

Questions about this item

How can I verify the LUOM HDMI2SDI is converting my 1080p 60Hz HDMI source correctly after connecting it?

Check the LED indicator on the unit; it shows power and signal lock. Both SDI outputs should display the same 1080p 60Hz image on your SDI monitors at 2.97 Gbit/s without artefacts.

What comes in the box with the LUOM HDMI2SDI and do I need to buy any cables or power adapters separately?

The package includes the converter, a power supply and a manual. You must supply your own HDMI Type A cable and two SDI cables (BNC) to connect the dual outputs.

Which SDI standard should I select on the LUOM HDMI2SDI for a 1080p 60Hz feed to run 100 metres over coaxial cable?

The converter auto-detects the format; for 1080p 60Hz it will output 3G-SDI (SMPTE 424M/425M-AB) at 2.970 Gbit/s, supporting up to 100 metres on standard coax.
