DisplayPort artifacts & connection lost

My screen sometimes shows a "line" or artifact for a very brief moment, or sometimes the screen goes black and then comes back online and I believe this is because of static as I have a fabric chair after doing some research. The problem is, I don't know how to stop it, its getting quite bad and annoying. I have tried changing DP cables and searching for "Shielded" cables but found nothing.

Is there anything I can do to shield the cable to prevent signal loss?

I have also read this

But still clueless on what to do.

RMA or get a new monitor.

I've used the same monitor for 5 years now

Displaylink isn't DisplayPort.

Have you tried a different monitor? If its static, how is it being transferred from you, to the monitor?

Have you tried a different cable?

I know its static because I can sometimes get a static shock from the metal on my chair lol.

Actually JayzTwoCents shows the issue here

How is it transferring to your monitor? 
 

Feel free to answer the other two questions.

I have a second monitor that doesn't flicker, maybe its DP is grounded differently?

I have no idea how it transfers to the monitor, I have hard flooring but can't ESD transfer through the air?

Not that far. What is your monitor sitting on, is it a conductive material?

On a dual monitor arm mount but is mounted to a wooden desk

Related, sorta.

I have a short in an old computer here that I never found. Whenever static electricity was around (I live in a very dry climate), and I touched my keyboard, it would cause the machine to reboot. That was a metal chassis keyboard though and it was travelling down the USB cable.

Anything in particular on that monitor arm that connects to something you are touching? See my above story. Electricity needs a path and I don't think static is strong enough to travel that far across the open air and certainly not wood.

Go get a large esd mat and sit on it

You can also do what we do at times: Run a humidifier in the vicinity of your monitor.
