# Signal Range

OmniScope can monitor signal in both Video (legal) and Full (data) range. To get accurate readings, the signal range settings must match between your source application and OmniScope.

In DaVinci Resolve, go to Monitoring settings where **Data levels** can be set to **Video** or **Full**. When set to Video, you can also enable **Retain sub-black and super-white data** to monitor signal outside of the legal range.

To make sure the signal is displayed correctly in OmniScope, open **Input Settings** (from the **Connect** menu or the gear icon in the toolbar, then the **Settings** tab):

The key setting is **Expect video range**. If **Data levels** in Resolve's Monitoring Settings is set to **Video**, then **Expect video range** should be enabled here.

To monitor out-of-gamut values (outside legal range), make sure **Retain sub-black and super-white data** is enabled in Resolve's Monitoring settings, and uncheck **Scale the video/SDI range to the full range** in OmniScope (**Options / Preferences / Signal**). Otherwise out-of-gamut values will be clipped.
