Random black screens on a Mac mini M4 are usually caused by the display or cable, not the Mac. Diagnostic order. 1) Cable: replace the USB-C / HDMI cable with a known-good one. Cheap HDMI 2.0 cables can't reliably carry 4K@60Hz over 2m+. Try a different cable first. 2) Refresh rate: open System Settings → Displays → drop the refresh rate by one step (120 to 60 Hz, or 60 to 50).
Many monitors handshake correctly initially but lose sync over time at the highest rate. 3) Display sleep: System Settings → Displays → Advanced → check "Display sleep when Mac is on" - if set too short, you may be seeing display sleep, not a fault. 4) Monitor input auto-detect: turn the monitor's HDMI/DP auto-input off in its OSD; force the correct input source. 5) HDR / Dolby Vision: turn off on macOS side if the monitor doesn't fully support it. 6) macOS update - install latest version.
We test displays free at our Dubai workshop.
