“What is the power source? Does it use power from TV through HDMI? Or does it need additional power cable? Can it be plugged into a 4K TV and expect good resolution?”

• There is an AC adapter that plugs in to this system to power it. You can plug it in to a 4K TV, but the maximum resolution for the Atom processor is 1080p

• It has an external power supply. It does not receive power from the HDMI. Also if you plug in a wireless keyboard connector you have no USB connection left.
