The Dell S2725QC is a 27" 4K USB-C monitor that typically works plug-and-play with Apple silicon - but a few issues come up with the Mac mini M4. Fix in this order. 1) Cable: the S2725QC ships with a USB-C cable rated only for video + 65 W power; if you're using a third-party cable, verify it's USB-C with DisplayPort Alt Mode (most generic ones aren't). Use the Dell-supplied cable to test. 2) Firmware: update the S2725QC firmware via Dell Display Manager (Mac version available).
Older firmware misses EDID for some Apple silicon configurations. 3) USB-C port choice: connect to a different Thunderbolt 4 port on the Mac mini. The S2725QC negotiates power and video at handshake; if the Mac mini was sleeping when the cable went in, it may not renegotiate - unplug for 30 seconds, replug. 4) Reset SMC equivalent (full shutdown, unplug 30s). 5) Check System Information → Graphics/Displays.
