Just installed my new monitor, all settings seem fine I'm running 165Hz. From time to time it seems to lose contact/reset/turn dark, but returns. I've observed it at the moment just in Linux using Nvidia driver: 515.65.01. It does not seem to be a system config since I had never suffered with the old monitor and have changed not settings. Sample of the issue.
More people with same issue:

Hmm... Let's cover a bit of a basic question.

Are you using the same HDMI cable?

I had one monitor that was really sensitive and I really had to make sure the cable was seated with far more force than one might think. So, there's that as well. Any vibration or movement would cause exactly what you're seeing there.
