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.
