Every now and then, my monitor screen blackouts.

So, I bought a Mac mini 2-3 weeks ago and I'm having a problem with my screen display.

Occasionally, my monitor (Dell) blacks out for a few seconds then it becomes normal again. The blackout duration is not consistent, it ranges from 1 to 3 seconds and it can happen up to 6 times a day, on most days it only happen twice or 3 times a day.

While the screen is blackout, the system still runs as normal. For example, if I was watching YouTube and the blackout happens at 0:30 for 3 seconds, then I'd see the video continues to run at 0:33 when the screen turns back to normal.

Please help me to fix this.

Mac mini, macOS 12.0

Hi everyone,

Apparently, the problem happened because the Mac mini was placed near freezer. I notice every time the freezer activates (it makes hmmm noice), monitor screen turns black.

Relocating the Mac mini to a different position, far away from the freezer solved the problem.

Thanks.

Check for a loose connection, a loose HTML chord is usually the cause. Also open System Preferences > Displays to check your resolution. Sometimes a setting for higher than 60Hz has this effect.
