My Mac Pro has a flickering waterfall effect ?

I reset the prm and smc and safemode still has the problem on the monitor. It keeps getting worse. I also used diagnostics and found no issues. I updated to the latest Catalina and still no fix. If I use my hdmi it works perfectly in the tv but this monitor still has the problem. This is a major MacBook Pro 13 inch mid 2014. Any tips?

    You have a hardware problem.  Might be power, or motherboard, or the display panel, or the cable through the hinge.  Repair shop is recommended.
