Learn how to power and connect a Mac mini M4 docking station for an 8K 120Hz DisplayPort monitor, including order of connections and common pitfalls.
Quick answer
Connect the dock’s power supply first, then link the dock to your Mac mini M4 with its USB-C cable, and finally connect your monitor to the dock’s DisplayPort output. This order ensures the dock is fully powered before the Mac negotiates the display signal.
Why power sequencing matters for 8K 120Hz stability
A docking station that supports 8K at 120Hz over DisplayPort draws significant bandwidth and power. If you connect the monitor before the dock has a stable power source, the Mac may fail to detect the display or fall back to a lower resolution. Always power the dock first, then connect the host cable, and finally attach the monitor.
When your monitor doesn’t support 8K 120Hz
The UGREEN Mac mini M4 Docking Station can output 8K at 120Hz via DisplayPort, but your monitor must also support that resolution and refresh rate over DisplayPort. If your monitor is limited to 4K or 60Hz, the dock will still work but will negotiate the highest common format. Check your monitor’s specifications before expecting 8K performance.
Step-by-step setup
- Power the docking station: Plug the dock’s power adapter into a wall outlet and connect it to the dock’s power input. Wait for any indicator light to show the dock is receiving power. Common mistake: using a lower-wattage adapter than supplied—this can cause intermittent display dropouts.
- Connect the dock to your Mac mini M4: Use the included USB-C cable to connect the dock’s host port to a Thunderbolt or USB-C port on your Mac mini M4. Avoid using a hub or extension cable between the dock and the Mac. Checkpoint: the Mac should recognize the dock in System Information under USB or Thunderbolt.
- Connect your monitor to the dock’s DisplayPort: Plug one end of a DisplayPort cable into the dock’s DisplayPort output and the other end into your monitor’s DisplayPort input. Use a cable rated for 8K 120Hz if you want the highest resolution. Common mistake: using an HDMI adapter or a low-bandwidth cable—this will limit resolution or refresh rate.
- Verify display settings on the Mac: Open System Settings > Displays and confirm the monitor is detected. Select the highest available resolution and refresh rate. If 8K 120Hz is not listed, check your cable and monitor specifications. Checkpoint: if the option is missing, try a different DisplayPort cable before assuming the dock is faulty.
