Plug and Play installation on any Chromebook/Windows/Mac/Linux hosts which support DisplayPort Alternate Mode (Alt Mode) video output functionality. Adapter has been fully tested for functionality on the 2018+ iPad Pro (mirroring only)/MacBook Air/iMac and iMac Pro/MacBook and MacBook Pro/Google Pixelbook/Dell XPS 13 & XPS 15/Lenovo Thinkpad/HP Spectre x360/Samsung DeX capable devices/Surface Laptop 3 and Surface Go/and many other systems which support USB-C DP Alt Mode.
Most current phones and tablets with USB-C ports do not support Alt Mode video output. ASMedia USB 3.1 controllers do not support Alt Mode video output.
Most motherboards with dual USB-C/Thunderbolt 3 ports are limited to a single Alt Mode output; only one Alt Mode adapter supported per system.
4K 60Hz versus 4K 30Hz
4K 60Hz is only supported on laptops which support DisplayPort 1.4 (DP 1.4). Examples include the Microsoft Surface Pro 7, Surface Laptop 3, and the Surface Book 3.
4K 30Hz will be the maximum resolution and refresh rates for computers which do not support DP 1.4. For example, USB-C laptops which support DP 1.2 will be limited to 4K 30Hz. All lower resolutions will be supported at 60Hz.
Please contact your laptop manufacturer to confirm whether or not your computer supports DP 1.4 if 4K 60Hz is desired.
Connect the hub to a USB-C port that supports video and charging on your laptop, tablet, or phone.
Connect your USB peripherals, monitor, USB-C power adapter and SD/microSD card to the hub.
Note: Charging and HDMI output requires host device support for USB-C Power Delivery Charing and DisplayPort over USB-C Alternate Mode ("Alt Mode") standards.
This is the standard USB connection that most computers offered prior to the introduction of USB Type-C (USB-C). Even after the introduction of USB Type-C, this is still quite common.
It can provide data transfer rates up to the USB 3.1 Gen 2 (10 gbps) specification depending on the host and device, but does not directly support video in the way that USB-C Alternate Mode does. This limitation makes DisplayLink USB graphics adapters and docking stations ideal on systems that do not have USB-C, or in instances where more displays are needed beyond available video outputs of a PC.
This type of connection comes in a couple different styles depending on whether USB 3.0 and higher transfer rates are supported (bottom graphic). Usually this type of connection is used to plug into USB devices that do not have a fixed cable connected, such as USB docking stations, USB hubs, printers, and others.
One of the first connectors for charging a smartphone, wireless game controller (such as the Sixaxis and DualShock 3), and other small devices such as external hard drives. Not commonly used today, but is still used in some cases. Most devices using USB Mini B are using USB 2.0, though a USB 3.0 variant does exist. This specification also added USB On-The-Go (OTG) functionality, though it is more commonly implemented with Micro USB.
A smaller connector that serves many of the same uses as the Mini B connector, with added optional features such as Mobile High-Definition Link (MHL) to allow devices like smartphones to output video to larger displays without requiring a dedicated port for video output.
The larger variant of USB-B is most commonly used for external hard drives for higher 5Gbps transfer rates.
The most recent USB connection, USB Type-C (USB-C), represents a major change in what USB can do. The connector is smaller, can be connected in two orientations, is able to carry substantially more power and data, and can directly carry video signals of multiple types (HDMI, DisplayPort, etc.) Intel has also adapted the USB-C connector for use with Thunderbolt 3 and Thunderbolt 4.
It is important to note that while all Thunderbolt 3 and Thunderbolt 4 connections are USB-C, not all USB-C connections can be used with Thunderbolt 3 or Thunderbolt 4 devices.
No, this is not possible. Please note that DisplayPort to HDMI cables (as with most cables involving protocol/signal conversion) are not bidirectional adapters, which means they only work in one direction -- from a DisplayPort output to a HDMI input.
Connecting these type of cables backwards will not allow an HDMI output port (such as those on a dock) to function with a DisplayPort input on a monitor.
Computer networking is a complex topic. In this article, we'll be taking a deep dive on the nuances of network performance for those who need some additional explanation while striving to be concise, and to educate users of various experience levels relating computer hardware and computer networking.
If you just need to know how to perform a network performance test/benchmark, jump down to configuring iPerf.
Core Network Concepts
LAN vs WAN
With regards to network performance, it is crucial to first separate whether an issue is with Wide Area Network (WAN) performance, or if the issue is with Local Area Network (LAN) performance.
Your LAN is essentially the network inside your home or business. Many homes use a combination modem/router device provided by their Internet Service Provider (ISP). In some cases, especially in businesses, you may have a separate modem and router, along with other equipment connecting to the router such as a network switch.
Your modem, and the connection it establishes to your ISP—whether through coaxial cable, fiber, phone lines, or long-range wireless—essentially marks the point between the WAN and the LAN. The connection your modem makes to your ISP is the WAN, and any devices you connect through your router behind that modem belong to the LAN.
Almost every type of connection your computer makes to any piece of hardware will have a link rate of some kind. The link rate establishes how fast data can possibly be transferred across any given connection, but it does not guarantee how fast the hardware on either end of the connection will actually transfer data.
The concept of link rates, and their related bottlenecks, is likely best conveyed by giving an example of what connections might be involved in transferring a file from one computer on your LAN to another.
800Mbps—The file source is a USB 3.0 thumb drive capable of 100MB/s (800Mbps) read/write.
480Mbps—The USB 3.0 thumb drive is plugged into a USB 2.0 port on the PC, which has a maximum throughput of 480Mbps
1000Mbps—PC1's Ethernet connection establishes 1Gbps (1000Mbps) link to the router via Ethernet
300Mbps—The router connects to a second PC (we'll refer to this as PC2) via Wi-Fi, and it has established a 300Mbps link to the Wi-Fi adapter on PC2
480Mbps—The Wi-Fi adapter on PC2 is connected via a USB 2.0 port. The link rate of the USB connection to PC2 is at 480Mbps
6000Mbps—PC2 is going to store the file on an internal hard drive with a link rate of 6Gbps
1600Mbps—File Destination: SATA hard drive capable of 200MB/s (1600Mbps) read/write.
Following this chain, we see that 300Mbps is the slowest link rate established. This means that, regardless of the link rates established elsewhere, the absolute maximum the data can possibly be transferred is 300Mbps.
if we were to change the Wi-Fi connection to a wired Ethernet connection capable of 1Gbps, our performance bottleneck would then become the USB 2.0 connection to the USB drive where the file is stored.
Ports and Interfaces
A network interface represents connections, whether wired or wireless, that are made to form a network between devices.
Some may refer to physical hardware connections as "ports". For the purposes of networking, ports are logical constructs that can also be referred to as "network ports". Each network interface has 65,535 of these logical ports. Each port on a network interface is a separate data connection.
Benchmarking Network Adapter Performance
To properly benchmark network adapter performance, we need to:
Use a simple LAN configuration
Eliminate bottlenecks, especially link rate bottlenecks
Websites like speedtest.net, fast.com, and other performance tools in your web browser are going to use your WAN connection, and are not appropriate for determining if a network adapter is working well.
Transferring files from one computer to another on your LAN is typically not the best way to benchmark a network adapter. File transfers are bottlenecked by a number of things, including performance limitations of the disk the data is on, and often times a lack of establishing parallel network connections to perform the task.
One of the most accurate ways to benchmark network performance on a LAN is by using iPerf . To more effectively benchmark network adapter performance, it is best to establish a point-to-point connection between two PCs, rather than connecting through a router or switch.
Next, you'll need to run iPerf in client mode, targeting the IP address of the server/interface where iPerf is running in server mode. Additionally, we'll run the test for 30 seconds using -t 30 and with four parallel connections using -P 4. Running 4 parallel connections is optimal for saturating a network link.
Open Command Prompt
Press Windows Key + R or + R, then enter cmd in the window that appears
Search the Start Menu for Command Prompt, and open it
Navigate Command Prompt to the directory the directory where iPerf is located
The cdcommand is for 'change directory'
If you have a folder named 'iperf' on your Windows desktop, you can reach it in command prompt with the command cd %USERPROFILE%\Desktop\iperf
Run iperf in client mode via Command Prompt (replace 192.168.0.200 with the IP address of the server/interface where iPerf is running in server mode)
iperf3.exe -c 192.168.0.200 -t 30 -P 4
macOS / Linux
Run iPerf in client mode (replace 192.168.0.200 with the IP address of the server/interface where iPerf is running in server mode)
iperf3 -c 192.168.0.200 -t 30 -P 4
iPerf should start performing a network performance test. If the test fails to start, make sure that iPerf is not being blocked by your PC's/Mac's firewall.
Why iPerf is Ideal for Benchmarking
Unlike a file transfer, iPerf runs in memory on the PC and generates data to send using the CPU directly. This alleviates potential bottlenecks generated by storage devices, and allows you to explicitly control how many parallel connections are being used to transfer data rather than being unsure if parallel network connections are being used by other means.
There's a lot more to networking that isn't covered in this article, but we hope this helps explain enough to get an accurate measure of your network performance.
While all USB ports provide some amount of power for attached devices, the available power may not be enough for certain high-current devices such as USB hubs or external hard drives. High-current devices usually come with their own power adapter, making them self-powered, in contrast to a bus-powered device that draws all of its power from the host computer's USB interface. Bus-powered devices can cause issues if they need more power than is available from the host machine.
Many of our devices that include power adapters, especially USB hubs, will function in either self-powered or bus-powered mode. However, even though the device may function, each additional device attached to the host computer reduces the total available bus power. If the power runs out, any USB device attached to the computer may suddenly disconnect. If this were to happen to a USB storage device, such an event could result in permanent data loss.
If a device comes with a power adapter, we recommend that the adapter stay connected at all times, otherwise the device may not function as designed.
Self-powered USB device - A device that takes all of its power from an external power supply
Bus-powered USB device - A device that takes all of its power from the host computer's USB interface.
As is the case with most electronic devices, it is expected to observe that the aluminum shell of the USB-C hub gets warmer, particularly if the USB-C passthrough charging and/or all ports on the hub are utilized.
Internal testing has measured and validated operating temperatures of up to 125°F with our USB-C hubs, which is well below the maximum rated temperature of various integrated chipsets (IC) in our USB-C hub of 212°F.
In summary, please note that heat is not an indication of an issue or defect with the USB-C hub.
Yes, but only if your computer is equipped with a USB-C port that supports DisplayPort 1.4 (DP 1.4). If you're not sure if your laptop supports DP 1.4, please contact your laptop manufacturer to confirm this important detail.
Examples of known laptops which support DP 1.4:
MacBook Pro 15” 2018 / 2019
MacBook Pro 16” 2019
Surface Pro 7
Surface Laptop 3
Surface Book 3
If DP 1.4 is not supported, then the maximum resolution and refresh rate of the HDMI port on the USBC-7IN1E adapter is 4K 30Hz.
Please note that the adapter will not drop the USB 3.0 ports to operate at USB 2.0 speeds to support 4K 60Hz. DP 1.4 must be supported for 4K 60Hz.
When the USBC-7N1E adapter is 'passing through' power from an external USB-C power adapter to the host laptop, a small amount of power from the USB-C power adapter is used in order to power the USBC-7N1E adapter itself.
The net result is that the amount of power provided to the host will be slightly less than the full power provided by the USB-C power adapter. Depending on power thresholds set by the laptop manufacturer, this may result in a warning that the system is charging at a slower than expected rate.
'No Charging scenario':
If the USBC-7N1E adapter is connected to the host laptop without a USB-C power adapter attached, the USBC-7N1E adapter will draw power from the laptop in order to power itself. If an external USB-C power adapter is then connected to the USBC-7N1E, the laptop may not start to charge.
This is because not all laptop models will reliably 'switch' the flow of power. Should this occur, simply disconnect the USBC-7N1E adapter from the host laptop. Once disconnected, connect the external USB-C power adapter to the USBC-7N1E adapter and then connect the combined assembly to the laptop. The laptop should now be charging.
