Ensure your USB‑C port can deliver at least 10W for the monitor. Some laptops and phones may not supply enough power. When in doubt, use a 45 W or higher external charger to feed the monitor and charge the laptop. This avoids issues like “usb‑c portable monitor not working” scenarios where cables or power are insufficient.

- Use a quality USB‑C to USB‑C cable rated at 5 A.
- Plug into either side USB‑C port of the M14.
- Connect the other end to your laptop that supports DP Alt Mode.
- If your laptop has only one port, you can plug in a USB‑C charger to the other port on M14 to supply both monitor and laptop charge simultaneously.
If no signal, check cable quality or lack of DP Alt support. Reddit users confirm a MacBook setup worked with proper USB‑C to USB‑C cable and charger; poor cables or chargers led to monitor sleep mode.
