The screen sometimes goes black for a second or two randomly.
replacing your HDMI cable
I think you’re onto something. I have two HP cube shaped docks on my closet now waiting on a return box. The third is holding, but only because there’s also a reg key for windows that will lose compression on the HDMI and make it not resynch so often.
I still get the blinks, but they’re daily instead of hourly. I can dig it out if it’s valuable and the cables are good.
I’m also using a steetek/PWay/etc 2x2 HDMI KVM switcher downstream of that dock, so I can switch between two contract desktops for my k,v and m as the day cleaves to night.
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.
Have you tried replacing your HDMI cable? That might causing the Docking station issue

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.
