Mac Mini 2023 using 3rd party monitor intermittently goes black I have tried 2 monitors. One is black all the time...and the other goes black for a few seconds and turns on constantly. I'm running on 14.4.1. Monitor people say it's the MAC Should I send this in for repair before the standard warranty expires? Or has anyone had this issue with the new OS?

All monitors suddenly are black? This morning I signed into my MacBook, and my external Samsung monitor is black. It's still recognized and I can "move" windows to it... Everything seems operational on my MacBook's internal monitor. But the external monitor is black. I've used this monitor for years, never had a problem. So I tested another monitor, this one an Acer. Same deal. The MacBook sees it, connects, and thinks its live, but the monitor is black. I tried unplugging, waiting, restarting. All the cables are fine. Everything is plugged in. Nothing changed (except I updated Ventura -- but the problem was happening before I upgraded, and I was hoping the update would help fix it). I'm on a MacBook Pro, M1 Pro chip, Ventura 13.3.1.

Test a short Premium Certified HDMI cable or.. get and use a USB-C to DisplayPort 1.4 cable.

Personally I would use a USB-C to DisplayPort 1.4 cable instead of an HDMI cable.

I urge you to test a USB-C to DisplayPort 1.4 cable like the one I recommended above.

HDMI is best 👌. Use HDMI cable 1m (3 feet) or less, should fix.

What external display...?

(brand and model)

How is the display connected to the Mac mini...?

(cable type and adapter if one is used)

Replace the cable with new and try? If that doesn’t fix, return it and I’d then buy a new HDMI monitor. Others may recommend trying the DisplayPort port with a dongle. IMO, it’s obsolete tech and not worth the money (or trouble), your choice.
