Hi
I have in my HP Z4 (Xeon 3.7, 32GB RAM, RTX 2080 Super) I did installed an old Decklink Quad-card I had lying around.
I configuret it as 1IN, 2,3&4 OUT
The problem is that there is minutes of delays and framedrops in the SDI (1080i50) compered to my displayport. In Aximmetry my processorload is minimal GPU 20%, CPU 17, FPS 30, VMem 20.
Is the card just to old and I need to change it to a Duo2 or is there something that I have forgot to check?
My version is Broadcast DE 2020.8 and decklink-driver is 11.7

Hi Markus,
Try to lower the "In to out latency" in Preferences / Video Input.
Try to find the lowest value that does not yet give the "Cannot keep latency" error.
Please note that you'll never get the low latency of your displayport, since SDI cards have an internal buffering in order to provide a smooth output.
