Insufficient Power Supply
There is a limit power output for smartphones. For moniotrs with larger screen size like 22 inche, higher resolution like 4K or refresh rate, it always need more power input. Power up the monitor with the power socket include in the package or use a PD power bank. To charge your portable monitor, choose a power bank that supports the PD Protocol Type. Lower-wattage banks may only support PD 1.0 or 2.0, which might not be enough. Check the table for outputs and protocols. Select a bank with a rating equal to or higher than your monitor's charger, such as 65W or more if your charger is 65W.
Power Output | PD Protocol Type |
5W - 10W | PD 1.0 / PD 2.0 |
10W - 18W | PD 2.0 / PD 3.0 |
18W - 30W | PD 2.0 / PD 3.0 |
30W - 60W | PD 3.0 |
60W and above | PD 3.0 |
