A:Answer Hi there. Thank you for sharing your inquiry about the LG 24MK430H-B monitor. We understand your question regarding the power source for the unit.
We can confirm that the monitor does, in fact, include a power cord and adapter. The monitor cannot power itself solely through the HDMI connection to your Mac mini; it requires a separate power source to operate.
For the 24MK430H-B monitor, the power setup is as follows:
Power Type: The monitor uses an External Power (Adapter). This means it has a power adapter box that plugs into a standard wall outlet.
Included Accessory: The list of included accessories confirms that a Power Cord is provided in the box, which connects the external adapter to the wall.
Connectivity: The monitor uses the HDMI Cable (which is also included) to receive the video signal from your Mac mini or other computer, but the power function is handled separately by the adapter and cord.
