Mac mini M4 supports up to three external displays - but only with the right cables and ports. First, confirm the cable is rated Thunderbolt 4 or USB4 (40 Gbps) - many "USB-C" cables are USB 2.0 charge-only and won't carry video. If you're using a hub, ensure it's a powered Thunderbolt 4 hub, not a generic USB-C dongle. Try plugging the monitor directly into the Mac mini first to rule out the hub. In macOS, open System Settings → Displays and press "Detect Displays" while holding Option.
If the monitor still doesn't appear, reset the SMC and NVRAM (Apple silicon resets automatically on restart), then check that the monitor is set to DisplayPort 1.4 or HDMI 2.1 mode, not legacy. Bad cable is the cause 70% of the time. Bring it in - we test cables and ports on the spot.
