Hi, I have a problem. I have in vmix connected 3 cameras in 1080 50i, the vmix, a geforce 1050 ti, and a decklink duo 2, all set to 1080 50i. when the signal is played by the geforce by hdmi, it makes me a little strobe, but when I play with the decklink by sdi the video comes out fluid, what could it be?

What display ? A computer monitor? A TV set ? A Videoprojector ? A field monitor ?

Make sure the display supports 50i or 50Hz (or 25 Hz)
Very few computer monitors support interlaced signals as computer are progressive by default.

To ensure the correct broadcast standard, you will need to use the Decklink output when connecting to the ATEM.
The fullscreen output is intended for displays only.

I got this to work fine with an HDMI out and an ATEM. Thing is to use a splitter on HDMI out, set the nVidia HDMI OUT for 50Hz (or 25 Hz, it might vary), connect a display (TV set or field monitor) that shows 1080i50 for the source and THEN, finally, connect the splitter's second port to the ATEM.

Alternative is to use something like a Decimator or equivalent

Obviously as Martin said using the Decklink Duo 2 is another working option.
