# DeckLink & UltraStudio

Nobe OmniScope supports any BlackMagic input card. It will be detected automatically and displayed in the “Connect to…” dialog box.

OmniScope requires **DesktopVideo 10.10 or later**.

### Checking the current device status

You can check the device in Help / DeckLink window:

### DeckLink Unavailable Message

If OmniScope cannot access a DeckLink device at startup (for example, the device is in use by another application or the driver is not loaded), the input source will display a clear **"DeckLink unavailable"** status message instead of a blank or generic error. Check that no other application is capturing from the same device, then reconnect the source.

OmniScope also handles the case where a DeckLink device reports no name string — device enumeration will complete normally instead of crashing, and the device will still appear in the source list.

### REC Badge

When a DeckLink or UltraStudio source is actively recording, OmniScope shows a **REC** badge on the input tile. This gives you a quick visual confirmation that recording is in progress without needing to open any additional windows.

### Pass-Through and Feedback Flashes

On cards such as the DeckLink 8K Pro that use Desktop Video-managed port profiles, OmniScope correctly preserves the profile on connect and disconnect. If you experienced SDI/HDMI feedback flashes on disconnect or app exit, this was fixed in version 1.11.39.

### Diagnostics View (1.11.19+)

Open Input Settings for a DeckLink or UltraStudio source and select **Diagnostics** to see live signal and device health (format, link, queue state). Use this view when troubleshooting capture stability or pass-through issues.
