I updated the DeckLink 4k Extreme latest driver and I dont see any video.
I have a SDI output and a HDMI output.
my Blackmagic Desktop video utility says that the output format is NTSC
the 1080PsF On is on
the SDI configuration is dual link
Video input is SDI
when I playback sd video 720x480 I can see video signal but when Im in HD I dont see any video, before I could playback SD and HD with any problem.
