HP Recommended
Product: HP Envy 27" 4k
Operating System: macOS 10.15 Catalina

So my setup is:
MacBook Pro (15-inch, 2016)

I am connected to HP Envy 27" 4k via a cable USB-C to Displayport.

The issue:
On 4k resolution as soon as some faster action happens on screen the monitor flickers to black and back. As it switches off an on. I saw there was a similar thread with a windows setup.

What I tested and tried with ZERO result:
Unplugged and plugged the cable 😛- didn't work
Unplugged monitor and disconnected every single cable for about  30 min, plugged back in- didn't work

Connect to every single port that my mac has- didn't work
Switched my Radeon Pro 460 4 GB to Intel HD Graphics 530 1536 MB that the mac has- didn't work
Tried the same cable on a Different monitor no flickering on 4k- didn't work
A Different cable on the same monitor still flickering- didn't work
Apple adapter to HDMI cable 1920x1080 no flickering bad image quality obviously- didn't work

Apple adapter to HDMI cable maxed out to 2k no flickering - didn't work
I tried also swearing - didn't work

 

Frustration Lvl maxed out also... 😛 😵

So what would you do in my position... 😅 BTW my first ever experience with HP monitors... and maybe my last
