hi
I want to use SignalGenHDR in DeckLink 4K pro card.
when I run the sample SignalGenHDR , the application run but I can not control any item in application.
I try and get the same result both win and ubuntu.
and another sample SignalGenerator can run normally.

Hi Eager,

The purpose of the SignalGenHDR sample is to demonstrate how to output HDR and colorspace metadata in an output video frame. On device discovery, the SignalGenHDR sample filters devices that support both Rec.2020 and HDR metadata, against attributes BMDDeckLinkSupportsColorspaceMetadata and BMDDeckLinkSupportsHDRMetadata respectively.

Regards
Cameron
