HDMI Connectors already provide 5V power. Why can’t the cable just use that power? Active HDMI Cables can require more than the minimum power supplied by HDMI source devices. A source device that supports HDMI Cable Power can provide higher power and can indicate this capability to the cable.
Can a monitor work without a power cord?
Yes, monitors require the power cables that come with them. HDMI can be many sizes from maybe 3′ to 6 or 10.
Can HDMI port be used for charging?

Why is my HDMI sparking?
When connecting a floating device to a grounded device like a PC with 3-prong mains plug, the charge discharges and the potential between devices equalize. As the voltage difference could be approximately half of the mains voltage, you see a spark.

Do monitors use PC power supply?
No, monitors are powered by their own sources.
Are all USB ports powered?
Most computer USB ports supply 5V of electricity with a maximum current of 0.5A. This amount of current is standard across the majority of computers and means the overall power output will be 2.5 Watts at best. Later USB designs bring that current up to 0.9A.
Can I use a USB charger as a power supply?
Yes, you can use a USB-type battery charger as a power supply. As we saw earlier, a USB battery charger is a Type A charger that holds a voltage making it easier to use as a power supply. These types of chargers are commonly used with mobile devices like smartphones, digital cameras, etc.
