# Gamut Check

Gamut Check is a GPU based, real-time frame processing that detects any out-of-gamut values in the incoming (unmodified) signal:

Gamut check works together with Error Logger scope. In order to start logging the gamut errors, Gamut Check needs to be enabled.

{% hint style="info" %}
Please note that Gamut Check processes the unmodified input frame in real-time which might affect the performance of the application. Furthermore, if the machine is not fast enough and dropped frames occur - the end result of the gamut check can't be trusted simply because it missed some frames during the process.
