Decklink 4K Extreme 12G with 2SI Output

PostWed Sep 25, 2019 7:22 am


is there any chance to configure the output in quadlink mode to 2SI on a Decklink 4K Extreme 12G ?

I tried to configure the device based on but it did not work.
Code: Select all
IDeckLinkConfiguration* pConfig;
if (m_pOutput->QueryInterface(IID_IDeckLinkConfiguration, (void**)& pConfig) == S_OK)
   HRESULT valSet = pConfig->SetInt(bmdDeckLinkConfigQuadLinkSDIVideoOutputSquareDivisionSplit, FALSE);
The result (valSet) is E_INVALIDARG.
Is there a way to check if the device supports 2SI output?

Hi Steffen,

The bmdDeckLinkConfigQuadLinkSDIVideoOutputSquareDivisionSplit configuration setting is available for the DeckLink 8K Pro and UltraStudio 4K Extreme 3.
