What does HRESULT 0xC00D10BE (NS_E_DISPLAY_MODE_CHANGE_FAILED) mean?

NS_E_DISPLAY_MODE_CHANGE_FAILED

Diagnosing NS_E_DISPLAY_MODE_CHANGE_FAILED in Player settings or the playback graph

NS_E_DISPLAY_MODE_CHANGE_FAILED (0xC00D10BE) is returned when the Player could not switch the display device into the mode requested for full-screen playback.

Separate Network-object configuration, graph capabilities, graphics presentation, stream selection and COM ownership before changing playback content. The relevant condition is the Player could not switch the display device into the mode requested for full-screen playback.

One-variable verification

1. Capture the resource identity and current and requested resolution, refresh rate, color depth, multi-monitor topology, exclusive-mode owner and driver result.
2. Verify that the caller uses the current Playlist, Media, Network, graph, device or DRM object instance.
3. Run the narrow experiment: use windowed playback first, then request a display mode already listed by the active adapter.
4. Do not combine this focused test with a codec-pack change, Player reset, or broad registry cleanup.
5. If the retest returns a different specific HRESULT, diagnose that new failure as the next stage.
