Front USB-C is not the Mac mini M4 video route

Apple lists display output on the rear Thunderbolt ports. The front USB-C ports are USB data connections; a matching connector at the front is not the documented video path. The M4 model has rear Thunderbolt 4, while M4 Pro has Thunderbolt 5. Apple: Mac mini 2024 specifications

  1. Connect the desktop to its own mains power.
  2. Use a rear video-capable Thunderbolt port and a cable matching the display input.
  3. Select the monitor input, then the supported picture mode in macOS.
  4. Add further screens only using the model’s documented output combination.
