Elgato HD60 X passthrough works but capture is black

HDMI passthrough and USB capture are separate paths. A working TV/monitor passthrough proves the source reaches the HDMI output path, not that the USB host is receiving a supported capture format.

QUESTIONWhy does HD60 X passthrough work but OBS/capture is black?

Start with evidence

Run the tests that separate the likely branches

Decision table

What the observation changes

ObservationWhat it meansNext action
Passthrough works; capture device not detectedHDMI source path is present; USB enumeration/path is higher priority.Test HD60 X direct on a USB 3 host port/cable.
Device detected but black in all capture appsFormat/source/HDCP becomes more likely.Use a known unprotected supported source format.
DeviceOK/browser receives frames but OBS is blackCapture hardware path is partly proven.Check OBS source selection/resolution/other app contention.

Sequence

Work from reversible checks to escalation

  1. 01

    Remove USB hub and connect direct.

  2. 02

    Confirm a supported unprotected HDMI source.

  3. 03

    Check capture device in browser/another app.

  4. 04

    Match OBS source to the actual HD60 X mode.

Likely areas

When to stop changing settings

If USB enumeration/capture fails across known-good supported hosts and sources, use Elgato support.
