Only two cables are required to operate the HP E24D G4 Advanced Docking Monitor with a computer or laptop: one supplies the monitor with electricity, while the other is a USB-C cable that connects the monitor to a computer and, in turn, supplies it with power. The monitor and computer are switched on together by the monitor’s power switch. The monitor is also equipped with interfaces such as Ethernet, Wi-Fi, USB, a microphone and a webcam.
