First

First double check that you have a secure connection at both ends. Next test with a different adapter. Or connect the display to another system, see if the symptoms follow the monitor.

If they don't follow the monitor it's either the adapter or the port. If you have another adapter, and the problem persists, you need a new logic board. You probably wiggle the cable to get it out, and that in turn weakens the solder joints from the port to the logic board causing intermittent signal failure. You can also test this if you bend the adapter cable and the symptoms stop. Of course doing that long term will only exacerbate the problem, so don't go getting any ideas.
