USBC-PDMON requires ~15W of power to operate. If the monitor is connected to a device that cannot supply enough power, the display might not turn on. Oftentimes, devices like smartphones and tablets are limited in the amount of power they can provide, so it's common that this issue may occur when using USBC-PDMON with devices like these.

Solution:

To power the display directly and ensure it functions properly, follow these steps:

1. Locate the Power Delivery Pass-through USB-C port on the right side of the USBC-PDMON, identified by a plug icon.
2. Connect a USB-C power supply (e.g., a laptop or phone charger) to this port.
3. The monitor will now draw power directly from the power supply.

Note: Make sure the USB-C power supply can deliver at least 15W to meet the USBC-PDMON's power requirements.
