Decklink Mini Monitor 4K blackouts

I have a Decklink Mini Monitor 4K connected to an Asus PA32UCX-K monitor. When using this setup with Davinci Resolve (both 17 and 18), I sometimes get blackouts on the screen for a few seconds before it comes back. This seems to happen only when I actually hit play, almost never when it's paused and just displaying a still image. If I'm in HDR mode, when the picture comes back from blackout, it displays the message "HDR ON" like this particular monitor always does when the signal changes. I don't know if that helps pinpoint it.

Anyone had similar problems to this?

I have suffered same problem. my monitor is PA32UCG-K. did you solve the problem?

Having similar and worse issues. I have it installed on a high end Windows workstation. have installed this in three different slots . . . x16, x8 and x4. They all do the same thing. Blackouts, crazy full screen distortion with green pink stripes, glitching bars, etc., have installed 4 different versions of the software, have tried every conceivable setting in both the desktop software and Resolve. If I reboot the computer once or twice, it comes back and is usable, but when I boot up the next day, it starts all over again. WTF!!!

My monitor id PA32UCR which has no issues with decklink HD, so it's definitely the card.

For those still struggling with this, it was solved by using an HDMI splitter between the monitor and the Decklink card. No issues since.

I solved the problem throwing decklink to the trash can and buying ultrastudio…

Hellow Shadewind, great you fixed it.
You say that you fixed it "by using an HDMI splitter between the monitor and the Decklink card".
Was that a 2 x HDMI in and one out or a 1 x HDMI and 2 out?

I have had the intermitent balckout problem when playing UHD at 25fps out of a Decklink Mini Monitor 4K into a BenQ SW271C monitor. I just solved it by feeding a Blackmagic Micro Converter SDI/HDMI 12G from the SDI output of the decklink and using the converters HDMI output to feed my monitor. Problem solved.
