Comparison HP 26D32AA vs HP 72C71AA

The technology allows you to work at higher voltage, thereby increasing the transmitted power. USB hubs with Power Dlivery can not only charge smartphones faster, but also power more power-hungry devices, such as laptops.

HDMI is the most popular of modern multimedia digital interfaces. It is specifically designed for HD content and provides the transmission of high-resolution video and multi-channel audio through a single cable. HDMI outputs are mainly found in hubs connected via USB Type C and compatible with the Thunderbolt interface (see "Connection"). Essentially, to use HDMI, you will need to connect the device to a Thunderbolt v3 port — a "pure" USB Type C does not support video transmission. This capability may be useful if an external screen is intended for HDMI connection, but your PC or laptop lacks such ports, or they are occupied or unavailable for other reasons. HDMI can have different versions, which affects its bandwidth. For instance, to transmit 4K video at 60 fps, you need HDMI v 2.0 or 2.1. And multiple ports will allow you to connect more than one monitor.

The purpose of the digital DisplayPort is similar to HDMI — for connecting an additional monitor through the corresponding port.

The length of the cable supplied with the device. Mostly relevant for models with a non-removable cable that cannot be replaced.

A special security lock is typically used to secure a sturdy metal cable, with the other end attached to a fixed or heavy object. This makes "snatch thefts" and similar attempts to steal the device virtually impossible. The Kensington lock protection is especially useful if the device is publicly accessible — for example, on a display stand in electronics stores.
