External monitor keeps going black with my MacBook Pro M2.. Help me!

Mac

I’m having a frustrating issue with my MacBook Pro M2 and external monitors, and I’m hoping someone here can help or share similar experiences.

•	I tried using different monitors (GAMDIAS and N Vision screen).
•	Both worked at first, but then randomly went black / “no signal” even though the monitor power is on.
•	I’ve tried plugging/unplugging HDMI, restarting, shutting down, but nothing seems to fix it permanently.
•	Oddly, when I tested the same monitor on another computer(Windows), it worked fine, also worked fine too with another MacBook Air (like how it was in the beginning with my Pro M2) — so the issue seems to be with my MacBook Pro M2, not the screens themselves.
•	System Preferences > Displays doesn’t detect the monitor either.

Has anyone else experienced this with the MacBook Pro M2? Could it be a compatibility issue with certain brands of monitors, or maybe something with macOS settings?

Any suggestions (workarounds, adapters, settings tweaks) would be super appreciated. 🙏

Thanks in advance!
