Table 8. USB standards(continued)

NOTE: If you turn off your computer while charging a USB device, the device may stop

charging. To continue charging, disconnect the device and connect it again.

NOTE: On laptops, PowerShare feature stops charging the device when the laptop battery

charge reaches 10%. You can configure this limit using BIOS setup program.

USB-C Depending on your device, this port may support USB 3.1, Display over USB-C, and Thunderbolt 3

devices. For more information, see the documentation that shipped with your device.

Thunderbolt 3 (USB-C)

port

You can connect USB 3.1 Gen 2, USB 3.1 Gen 1, DisplayPort, and Thunderbolt devices to this port. It

enables you to connect to external display using dongles. Provides data transfer rates up to 40 Gbps.

Debug port The debug port enables a user to run the USB 3.0 ports in USB 2.0 mode temporarily for

troubleshooting purposes and also when operating system is reinstalled using a USB optical drive or a

flash drive.

eSATA

eSATA enables you to connect external storage devices, such as hard drives and optical drives, to your computer. It provides the same

bandwidth as internal SATA ports.

Your computer may have a standalone eSATA port or an eSATA/USB combo port.

Visual Graphics Array

Visual Graphics Array (VGA) enables you to connect to monitors, projectors, and so on.

You can connect to a HDMI or DVI port using the VGA to HDMI or VGA to DVI adapters respectively.

Digital Visual Interface

Digital Visual Interface (DVI) enables you to connect your computer to displays such as flat-panel monitors, projectors, and so on.

There are three types of DVI connections:

• DVI-D (DVI-Digital)—DVI-D transmits digital video‑signals between the video card and the digital display. This provides fast

and high-quality video output.

• DVI-A (DVI-Analog)—DVI‑A transmits analog video‑signals to an analog display such as a CRT monitor or an analog LCD

monitor.

• DVI- I (DVI-Integrated)—DVI-I is an integrated connector that can transmit a digital or an analog signal. This port is more

versatile as it can be used in both digital and analog connections.

DisplayPort

DisplayPort provides digital connection between your computer and display devices such as monitors, projectors, and so on. It

supports both video and audio signals. DisplayPort was designed specifically to be used with computer displays.

Mini DisplayPort

Mini DisplayPort is a smaller version of the DisplayPort.

NOTE: DisplayPort and Mini DisplayPort are compatible with each other but the ports and connectors vary in size. If the

port sizes are different, use a converter.

Advantages of DisplayPort

• Supports high resolutions and high refresh‑rates

• Supports 3D transmission

• Supports multiple display‑devices simultaneously

• Supports High-bandwidth Digital Content Protection (HDCP)

• Supports plug-and-play adapters that allow you to connect displays using older connection standards such as DVI, HDMI, and

VGA

• DisplayPort cables can extend up to 15 m (49.21 ft) without requiring signal boosters.
