I have had the problem with a variety of cables. I think its a software issue. Wiggeling the cable does not cause any issues. The screen never looses signal its just briefly black.
This is why I switched to display port. It seems to work so much better. Also see if your dock is overheating. I’ve had that happen in the past and caused flickering issues.

But I guess it can’t hurt to try more cables.

I tried displayport too. My main dell 4k monitor had some issues with it. I updated the firmware maybe it works better now.
I have two monitors. Depending on where I plug in, it uses MST or no mst.
Also good tip about the overheating but the dock has a fan and remains quite cool during operation.
It’s difficult to debug since sometimes it works for two days and on other days it hap’ens constantly.
