HDMI device not receiving signal from Decklink card

PostWed Feb 14, 2018 5:29 am


I have a board with HDMI IN and a HDMI OUT, and whatever is received on HDMI IN is looped to HDMI OUT.

Following connections are made
1). HDMI IN of the board - (Video source) Decklink card which sends frames at 720p @ 60fps in 8-bit BGRA format, using Testpattern code provided in Blackmagic_DeckLink_SDK_10.9.5
2). HDMI OUT of the board - HDMI TV.

Once Decklink card starts transmitting I am unable to see any output on the TV except for a blank screen.

Setup works fine with another video source which transmits video at the same resolution, frame rate and format as that of the Decklink card.

Please provide your inputs as to what might be the problem.

Waiting for any kind of help,
