USB A B C   4


USB Type C is a specification for a reversible plug connector for USB Devices and Cabling.  An important benefit of the USB Type C is that it supports USB4, USB 3.2, 3.1, USB 3.0, USB 2.0 and Thunderbolt Technology.  USB Type C ports can support a variety of different protocols using “AlternateModes”, which allows you to output Power, Data and Video Signals and use of adapters that can output HDMI, VGA, DisplayPort or other types of connections from that Single USB port.This allows for future devices to streamline their design to offer multiple output solutions through one singular output.

USB Version History

Developed in the 1990s, USB has become the most successful computing interface yet. The throughput has improved from 1.5Mbps to 40Gbps through standards evolution.

1998USB 1.x Low Speed LS 1.5Mbps Full Speed FS 12Mbps 
2000USB 2.0 High Speed HS 480 Mbps FS/LS 
2001USB on the Go USB 2.0 OTG Master / Slave configurable
2008USB 3.0 USB 3.1 Gen 1 Super Speed SS 5Gbps / HS/ FS / LS
2013USB 3.1 Gen 2 Super Speed + SS+ 10Gbps SS/HS/FS/LS
2014USB 3.2 Gen 2 Super Speed + SS+ 10Gbps and Gen2x2(Dual Lane) for 20-Gbps SS/HS/FS/LS
2017USB Type C USB 10Gbps DP 8.1Gbps and Power 100 W
2019 USB4 requires USB-C connectors

What is USB 3.1

“USB” stands for Universal Serial Bus and “3.1” is the recently released standard which indicates the technology and specifications it is compliant to.

USB Type C is nott he same asUSB3.1–USBType C is just a connector shape and the underlying technology could just be USB 2.0 , 3.x. Furthermore there are different USB Type-C 3.1 versions the “Gen1” and “Gen2”.

USB Type-C 3.1 Gen 1 means that the USB technology used is like USB3.0 (5Gbps).

USB Type-C 3.1 Gen 2 means that the technology used is USB 3.1 over 2-lanes(10Gbps).
To be able to send Video signals over USB 3.1 Type-C (Gen2) the source device (PC/Laptop) will need to have displayport Alternate Mode Support. Although Thunderbolt 3 is also coming out with a USB Type C connector, it is not the same as USB 3.1 Type C Gen2.

What is USB Graphic?

USB Graphic Technology allows you to connect almost any kind of display via a standard USB connector or cable. USB Graphics technology is available for USB type C only. The technology is designed to be simple and easy to use: just install the software, plug in your device and within a few seconds you have got a new monitor, docking station or projector connected to your PC. There is simply no easier way to add a display to your PC or Mac. Club3D offers a wide range of products from universal USB docking Stations to USB Graphic adapters.

For Apple users: Apple display settings will hide the resolution, so please hold down the option button on the Apple display resolution interface and then click zoom position of the resolution interface to display the hidden resolution. Then check the real resolution.

Video Performance
USB Graphic offloads all the heavy lifting of HD Video Playback and 3D Rendering to the GPU of your device. If your GPU performance is good you can even play games on a 4K Monitor.
USB Graphic provides support for HDCP which means that you will not get a blank screen when trying to watch the latest HD Movie.

Discover True Detail
4K also known as Ultra High Definition (UHD) delivers four times as much details as 1080p Full HD, that is eight million pixels compared to two million pixels, bringing more image clarity, fine detail and greater texture. Now you can embrace these technologies with just a free USB Port.

About USB4

The NEW Generation of USB4™ Technology is providing faster data performance, a better charging experience, the convenience of interoperability and certified reliability.
Key characteristics of the USB4™ solution include two-lane operation and up to 40Gbps operation over 40Gbps-certified cables. Multiple data and display protocols efficiently share the total available bandwidth over the bus. The USB4™ architecture defines a method to share a single high-speed link with multiple end device types dynamically that best serves the transfer of data by type and application. 

Summary - Bandwidth vs Speed

Bandwidth versus Speed
Bandwidth is the capacity available for use in data transmission. Speed is the rate of data transfer across the transmission path.
Maximum Amount
The bandwidth can be a higher value depending on the characteristics of the transmission medium etc. For a given network speed of a connection cannot be higher than the bandwidth of the network connection.
Unit of Measurement
The measurement for bandwidth in communication is Hz and bps in network connections. The measurement of speed is bps.
Communication Through a Bus Inside a Processor
The bandwidth is the amount of data transmits via the bus. The speed is the clock rate of the bus.

Difference Between Bandwidth and Speed

You might come across bandwidth and data transfer rate being used synonymously. While they are related, they refer to two very different measurements. Here is the explanation of differences. The key difference between bandwidth and speed is that the bandwidth is the capacity available for use in data transmission while the speed is the data transferring rate.

Bandwidth Bandwidth is the maximum potential data that can be transferred within a given time. The bandwidth is shared among all users of the bandwidth.

Data Transfer Rate The data transfer rate is the actual amount of data that is passed from one location to another over a given period of time. The most common example is a Link Aggregation where a number of Ethernet connection are bonded into a single interface. The bandwidth is the sum of the total connections but the speed is determined by the physical network connection.
