Common Micro & Mini Converters errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.
- Step-by-step fixGet the fix →
SDI-to-HDMI: monitor drops out or shows "no signal" only at 1080p50/60 (works at 1080p/1.5G)
Likely cause: Cleaning the signal (EDID manager or an inline Decimator) or using a compliant display resolves the handshake, not a converter fault.
- Step-by-step fixGet the fix →
HDMI-to-SDI feed rejected by a switcher/recorder downstream (3G-SDI won't lock)
Likely cause: Downstream broadcast gear keys off the SMPTE 352M payload ID to identify the 3G structure; a missing/incorrect ID makes it read the stream as invalid even though the picture is fine on tolerant monitors.
- Step-by-step fixGet the fix →
Intermittent dropouts / unit resets, especially on long or thin USB cables
Likely cause: Micro Converters have no battery and run entirely off the USB rail; voltage sag on a poor cable drops the unit below its operating threshold, producing intermittent loss that mimics a signal problem.

Monitor color looks off / want to calibrate the display fed by SDI to HDMI 12G
Likely cause: The onboard 3D LUT applies the color transform in the converter itself, so any dumb display downstream shows calibrated color.

Need to feed two SDI monitors from one HDMI source / signal degrades on a long BNC run
Likely cause: Dual reclocked outputs remove the need for a separate distribution amp and keep long runs clean, a common reason techs reach for this unit.
- Step-by-step fixGet the fix →
Wrong levels / 3G-SDI compatibility
Likely cause: Level A and B are two different 3G-SDI mappings; mismatched gear shows no or corrupted video on an otherwise good cable.
