Common Eco Capture 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 →
Capture app shows "No Signal" or "Unsupported Signal"
Likely cause: Eco Capture uses fragile miniature JST-SHD or FPC breakout cables between the card edge and the HDMI/SDI plug; a partially-seated or damaged adapter cable is the single most frequent cause of no-signal.
- Step-by-step fixGet the fix →
Capture frame rate is lower than expected (e.g. only ~80fps at 1080p, or drops when running multiple channels)
Likely cause: The FPGA pixel clock and PCIe DMA bandwidth are finite and shared; higher resolutions, more channels, and 4:4:4 formats each consume more, lowering achievable fps.

Card not detected — missing from OBS/vMix and shows as "Multimedia Video Controller" or unknown device with a yellow ! in Device Manager
Likely cause: A yellow-bang "Multimedia Video Controller" means the OS sees the PCIe device but has no driver; installing the Magewell driver binds it.

Eco Capture card not usable on a Mac / no device on macOS
Likely cause: Magewell ships no Kext/driver for Eco Capture on macOS, so the OS never binds the device regardless of connection method.

How to safely update firmware, and is a power-loss during flash dangerous?
Likely cause: The bootloader keeps a fallback image so an interrupted flash rolls back instead of bricking, but only on v1.21+ firmware — older cards should be flashed on stable power.
- Step-by-step fixGet the fix →
Multiple Eco Capture cards in one machine show identical device names — impossible to tell channels apart in software
Likely cause: The DIP switch writes a card index the driver prepends to every device name, disambiguating otherwise-identical cards.
- Step-by-step fixGet the fix →
SDI Eco Capture card glitches, drops lock, or freezes in a hot rack / hot venue
Likely cause: V1.9 firmware addressed a real thermal-stability bug on SDI models; combined with the card's narrow 0–40°C rating, cooling is the field fix.
