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
